DR650 project: transforming the stock carburetor! (BST magic)︱Cross Training Adventure

[@crosstrainingadventure]

Our complete DR650 project series here! bit.ly/3gQEStP HOW FAR DO YOU WANT TO GO? This video assumes you are fully derestricting the DR650 and using an aftermarket exhaust. Level 1: This is around two hours work and assumes you keep the stock exhaust. It costs nothing if you modify your own needle. - Modify the existing needle (or aftermarket) - Remove the rubber snorkel from the airbox - Reset the fuel/air mixture screw . Level 2: Around three hours work, you'll need an aftermarket jetting kit unless you modify your needle yourself and drill out the main jet. - Modify the existing needle (or aftermarket) - Remove snorkel and cut a second hole in the airbox - Replace the stock 140 main jet with a 150 main jet - Reset the fuel/air mixture screw. Level 3: five hours work, a great alternative to the expense of a pumper carb. It assumes you fit an aftermarket exhaust. - Modify the existing needle - Remove snorkel and cut a second hole in the airbox - Replace the stock 140 main jet with a 150 main jet - Reset the fuel/air mixture screw - Remove header pipe and grind back the inside weld - Shorten the carb slide spring - Drill a second hole in the carb slide. TUNING WITH MIXTURE SCREW When adjusting the mixture screw, don't go past two turns. If you need to in order to get the bike running well, you should go up to a 45 pilot jet. Fine tuning the needle? If you are really trying to get the best results, you can use very a very thin washer with the needle positioning to get half clip adjustments - if you are into fine tuning! Most of us won't worry about this. SURGING? You may find the bike surges. Often this occurs if you just take off the air filter 'door' instead of cutting a hole as specified in the vid. It might also occur if you cut too large a hole.

I've been fighting the carb on my 95 DR650 the whole time I've owned it (over 6 years) it came with a modified exhaust and the snorkel removed. I added a better filter and Dyno-Jet kit to try to tune the thing ...something was always wrong :-( I tried dozens of combinations of jet sizes and clip positions, I'm not exaggerating. it was never quite right. After watching this video I figured ...Why not? I dug out the stock needle, chocked it up in my Dremel and tapered it with some Emery cloth 'til it ...um, looked good? installed the modded needle with a small shim and installed a .150 jet. clipped 3/8 inch off the spring (What the hell is a millimeter?) I took the bike for a rip just now. it runs better than it ever has. I am flabbergasted! The goofy Aussie was right! This is EXACTLY what my bike needed. Thank you for posting this.

[@crosstrainingadventure]

Great to hear, and a big shout out to Gordon who supplied all the info and has spent countless hours over the past decade helping guys set up their DRs.

[@johnkopek7979]

On my 2002 dr650- the dynojet kit alone with 150 jet, changing needle & shims, and adjusting fuel air...it was a snappy, totally different machine. Added Leo Vince exhaust, grinded header weld, and removed snorkel/cut 2 holes in box. The difference between stock is mindblowing....

[@dr6507]

How much of a difference in mpg?

[@johnkopek7979]

@@dr6507 not sure of exact numbers but, like 30 less miles out of a tank

[@johnkopek7979]

It used to run out and have to flip reserve at like 125 miles. After the mods it runs out around 100 miles. Depending on riding conditions of course

[@dr6507]

​@@johnkopek7979thanks alot i really appreciate it! Another question did you grind the spacer down like he did tooo? Looks like he put the spacer under the clip, I've read where people put it above the clip

Looks like it makes more sense too put it under the clip .

[@markmtbrider]

"make sure your rubbers dont fall off" sage advice indeed.

[@gtpits]

It is sage advice, I lost one yesterday!

[@nev357]

I installed a jet kit in my DR 650. I drilled two larger holes in the plastic slide and enlarged the airbox top hole with a sharp Stanley knife really easily. I didn't cut the spring or need to adjust the mixture. I also installed a FMF powercore4 exhaust. The bike starts instantly, idles fine and is smooth throughout the rev range. Good gains all gears, no back firing. Rapt as.

I was reasonably happy with the dr performance but it really struggled to get the front wheel up without a decent clutch drop and pull up . I done everything In the vid except I purchased the pro cycle mid pipe . Started so much easier . Test ride was flawless . I actually think I got 10.2% more power 😂, it really goes so good , quick blip of the throttle and the front is up . Really is a great mod for a modest gain . Was easier than I expected thanks for the top vid 🙏🏻

[@dr6507]

Did you do the key needle just like he did with the spacer under the clip and did you grind down the spacer so it drops down past the shelf?

[@dr6507]

im in the U.S. and I know they say put the clip in the 4th slot from the top but I'm just curious as what too do with the spacer, that's why I haven't done it yet smh need too get it done tomorrow

Thanx heaps buddy. Did all that (with minor differances) used my bat drill against the grinder and then 1200 wet n dry to shape the needle and used a 1.5mm drill to open the 140 main to 150. Feels and sounds like a totaly different bike. Couldnt recomend this any better 👊🤘

[@TheRyadrian]

I have just done the mods on the carb airbox exhaust etc. I am now even more of a proud owner, of the dr650. Also I am now feeling like a motorbike mechanic. Life changer thank you very much all who have made these videos. Namaste

[@TheRyadrian]

The guy before me already upsized the jet although im not sure what make the jet is (155), cut the airbox open 80mm extra and a flowing exhaust with m/pipe. Also didn't have to stuff around with fuel/air adjuster. Am going to test the fuel/mileage and may go down a jetsize wanting around 22kms per litre! wish luck.

[@crosstrainingadventure]

i found the fuel economy stayed the same after the jetting mods... IF i didn't use the extra power!

[@SawyerKnight]

just by adding a better fuel filter and carb breather filter, also re-positioning it away from the carb box intake. I saw a boost in how the bike runs. no more surge with a steady throttle either. thanks for the tips fellas, love the vids. Oregon usa rider here, I'd take bug sounds over endless rain any day of the week haha

[@slimjim7411]

Honestly I messed around with these sort of tricks for years, and realize it's like trying to cut a foot off the bottom of a ladder, and taping it to the top to make it longer. You get a little more top end power, and myself always wound up with some dead or flat spot in the middle to low end somewhere. I went through a dozen combinations of jets, pull the carb 50 times, did runs and checked the plugs. In the end I just put a Lectron carb on. So people who want to open the airbox, and put a free flowing exhaust on that's my recommendation. Just save up for a Lectron or a pumper carb. The Lectron gets generally better miles per gallon, the pumper carb has the opposite effect. Dunno why but it does. However a Lectron carb is around $800, and a pumper carb can range from $400 - 650.

[@marcelcanuck]

i did all the mods recommended in this video and it turned out as they said it would , idles much better now and much more power on take off , the bike is much easier to handle at low speeds because of the extra torque the front wheel does come off the ground easily now witch is great in mountain riding condition

[@slimjim7411]

@@marcelcanuck Yeah my buddy did this to his, but he had flat spots too. Racers did this years ago because for example they might only care about how it runs at full throttle, or for a enduro hill climber might only care about low end torque. In generally stripping emissions stuff will get you a little boost. But none of it is like adding a pumper carb or a lectron carb performance wise. You're talking about a few extra foot pounds of torque, and better throttle response. Which is good but a pumper carb will make it a difference animal entirely.

[@marcelcanuck]

@@slimjim7411 i might of gotten lucky on the jetting , i ordered a 150 main and a 45 pilot , i never got a flat spot on my bike but i see allot of KZbinrs with that issue , i wasn't to impressed with the bike at first , it ran sluggish and stalled out at stop signs was just about to sell it when i spotted this video , now it's a keaper , might try to find a pumper and see what more i can get out of it , now that you've tickled my curiosity must be some on Ebay , be safe 👍

[@slimjim7411]

@@marcelcanuck Good luck I think pumpers are a little less expensive but you'll lose some MPG with the Lectron it's more like fuel injection it's just better everything but pumpers run around $400+ and Lectrons run around $600+ last time I checked at least for a 650 thumper.

[@superwilcox9026]

Shimmed the needle with a number 4 washer. Cut the spring. Cut 2 holes in the slide. Didnt cut the airbox though since i didnt want to rejet it. Runs good. The bike ran super lean before , now much better. The airbox cut may throw off the jetting which I did not change, and works good with stock jets.

[@88namiller]

I don't have a DR but I tried some of these things on my 125 Honda delivery bike and with a little trouble shooting I was able to get a decent power increase. Better response they l throughout the rev range, but especially in the lower revs. Thanks for the inspiration!

[@d.zimmer5646]

Just a little tip. At the carb is a small switch, good to see at 7:25, which reduces the power in first three gears. Just pull the plug out and the problem is away. Just try it, it's not a big diffrence, but i doesn't costs anything. I have done it on our DR 350, and you can feel it a little bit. Greetings from Germany. Love your vids. Since I'm watching your Videos on your Endurocross channel, I improved riding very much! Thank you Barry ;)

[@megasaxonzro9451]

Use a impact driver on the float bowl screws. Makes it easy and keeps them in good condition.

[@crosstrainingadventure]

+wajadog agreed. i think procycle do the screw kits but you could get them from any fastener specialist

[@mattplant7342]

I just did the airbox and slide/needle mods. The bike already had a staintune pipe and a 155 main jet. WHAT A DIFFERENCE!!! so much more grunt especially down low, it feels like it is 200cc bigger!

[@JagLite]

Excellent! You should be paid by Suzuki for your magnificent instruction video. (Yeah right, like that will happen) One thing I don't think you mentioned is that in the US we don't get the clip adjustable needle like other countries do. And our idle jet screw has a soft brass cover installed to keep us from having a good running engine. That is easily removed fortunately, and a very handy extended idle jet screw is available for easy, no screw driver needed adjustment. This vid is an excellent instruction on how easy the DR is to wake up from sleepy Zombie state to extreme enduro ready power.

[@crosstrainingadventure]

+JagLite48 damn, i should have remembered that. from memory you have to drill the carby as well to access the screw which is hidden on the US model.

[@timwilson4297]

Bought a '09 DR and tricked up the carb. and A?F box as per the video and put on a Delcovic stainless and carbon fibre exhaust....... magic, starts easily hot or cold, and goes like a jet....Thanks!

[@sjbechet1111]

Did this a few months ago - very noticeable improvement just with a 'Busa can and sorting that header weld out. Got 2 Busa cans taken off a new bike for $200, made 2 adapters and sold the spare system for more than the cost of the whole job. If you run a neat 3-4mm TIG weld round the header pipe collar you can make that internal weld flush with no issues. (6 months and 10,000k so far) For an adapter pipe - a standard 1 1/2, 45 degree bend, short length of pipe then a 90 deg bend cut in half to make the joggle worked for me (with a bit of grinding). I have a drawing of the Busa flange if anyone is interested - printing it out 1:1 and sticking it to the plate is easier than marking - don't use contact adhesive it will shrink the drawing.

[@crosstrainingadventure]

Great score on those two new cans! Roughly speaking you'll get 5% more power with the exhaust mod... then another 5% with the airbox and jetting mods.

[@aidangillett5396]

If anyone in OZ is interested in a GSXR pipe or FCR39MX pumper carb, I have both that came off my DR. The carb has been fully stripped, rebuilt and jetted appropriately for Australian conditions. Includes intake adapter and new clamps to make it fit Prior to selling the bike I refit the stock components, in all honesty I prefer the bike with just a jet kit and whats shown above. In fully stock trim it is a bit of a joke, but with an opened up airbox it sounds much meatier, and the carby mods can get you pretty good throttle response, at least 90% of the way to a pumper carb. However what I found is you need to either go for throttle response via overly rich jetting (overcompensates for a lean shift when cracking throttle open, so its actually the right mix straight away) or you jet for economy and suffer some throttle response. A pumper will get you both. But overall I enjoyed it with slightly reduced response because its a gentle giant. As soon as you start chasing those performance enhancements or big improvements it gets expensive and you're never really satisfied. It's always just going to be a DR

Thanks for sharing your expertise, I just want to add that when I taper my needle I plan to take a black marker to the areas of the needle I'm grinding off so it comes out even. I'll just keep applying more marker till I have the right shape.

[@billhamilton2366]

I'm having a bit of trouble with modifying / upgrading the carb on my DR. 1 My carb is from a 2003 DR. I purchased a noname BST40 rebuild kit on line. I received a new emulsion tube in the kit and it differs from the original. At Motolab I read their article on worn id of the emulsion tube which probably accounts for the heavy carbon deposits in the combustion cylinder. I read also the pilot jet was supposed to be 45.0 Mine revealed a 42,5. I installed the 47.5 I purchased from you. so far so good. (Motolab owner says there is no reason to replace the stock pilot jet.) I began putting the new parts into the carburetor and discovered the new emulsion tube from the rebuild kit is different from the original that I removed from the carburetor. I have 3 needles and none of them fit the ID of the needle jet. Yet all of the needles will fit the original emulsion tube. I have also read there are a couple of pre manufactured needles depending on the performance required. (ie: the DJ needle you mention above.) So what's going on here? Am I just a victim of parts made from Chinesium or am I missing something here? I've used most of my measuring equipment here. I don't need to measure the ID of the Emulsion tube. I understand the taper is considerably different from the needles I have, as well as the original Jet. Further to the original.. I have just now read notes on measuring the wear of an emulsion tube, and decided to insert each of the needles I have and measure the distance from the top of the Emulsion tube to the top of the needle when the needle is inserted till it stops. The original needle that came from the carburetor was protruding .910". The needle which was supplied in the rebuild kit protruded .888". the needle I purchased from Motolab (part number 13383-32E00 protruded .625. This indicates to me each of the needles tapers differently. I'm pretty confused at this point. I can be reached at [e-mail].

[@bikewolf7455]

i did everything thats listed in level three ( 0:15 ). with the extra drilled whole in the air box it loses a lot of power down low to the middle rev range and gains only a really slight amount of power in the far upper rev range. thats why i taped it off. also i got a different muffler (GPR Furore) which is unrideable in the lower rev range when the db eater is in. it stalls if you ease the clutch out. without the eater it has a lot of power and doesnt stall when easing out the clutch but its obnoxiously loud (comparable with a ktm 690 with leo vince x3 without db eater). also i never had the front wheel come up so easily. first time i got it up easily was last week when i changed the gearing from 15-41 to 15-45 and installed a high performance header pipe. still needs the upper rev range for me to clutch it up. im a noob when it comes to wheelies and probably dont have the right timing but it should be way easier on such a big thumper i think. i mean maybe she lost some power over the years and thats the reason.... shes 19 years old and has 70.000km on the clock

As always great info....after I tweaked my fully modified stock carb to my altitude and other components it ran well.then I installed a new tm 40 with a baseline jet set I determined all that tinkering to be a total waste of time....the usable power increase through the total rev range was evident immediately. Besides the Cogent Dynamics mohave pro and emulators with ohlins springs up front.....the tm40 was money best spent.

[@crosstrainingadventure]

Interesting to hear... some say the TM40 is better, others say marginal improvement but not worth the money. I've always had my stock carbs modified by the guy who came up with the 'BST magic mods' and he always nails it. I'm in the former category as I've also owned a DR with a TM fitted and couldn't see much difference at all. It would be very interesting to have both bikes perfectly tuned and put them on a dyno!

[@brianmarkey867]

I put a Q4 exhaust on my dr650 with a k&n filter and stage 2 carb mod. Definitely had to do the airbox mod I couldn't get it tuned until it was done. Also the Q4 is quite loud and produces humorous snapping and popping when you let off. Other than being almost annoyingly loud it is a much better machine after that.

My DR is bone stock engine/carb/exhaust. I enjoy the challenge of smoking everybody I ride with with it stock. Honestly it runs fine stock. Handling is what needs work on the DR much more then hop up bits. Its always miles ahead on any sort of dirt road.

agreed brad. i rode mine completely stock for a while and third gear wheelies were still a breeze.... but that suspension and those tyres were pretty scary when pushing hard on the dirt tracks lol.

[@TheRoamine74]

After study, DR650 is only lean on the needle. stock pilot jet and main jet are fine. So raise the needle is the only mandatory case to run OK (or silght shim). Rejet is not good for mpg but bike run cooler I admit.

[@505197]

I've never seen anyone take a needle to a bench grinder. If I was going to do that I'd chuck the needle into a drill. I have used a drill and sand paper to get a "better" taper. That way you get a more even finish and you can measure the needle and get repeatable results.

Man you guys are keen doing that with the carby still on the bike 😅 I just took mine right out

[@twowheeledsmurph]

Slagging Canadians at 8:48!! lol. I'm a Canadian and still love your videos! What a great mod. I'll be adding some 'J-Cloths' to my filter routine. Cheers!!

[@crosstrainingadventure]

unfortunately it gets much worse over on our dirt riding channel lol kzbin.info/www/bejne/oJ2rfKeFgNZmqJo

[@adventurecraig]

Great vid guys. I might pull my carby again. Greetings from sunny South Africa!

[@crosstrainingadventure]

+adventurecraig thanks craig... yes that carby seems to be a major key with unlocking the beast :)

[@adventurecraig]

+ADVENTURE OZ Just a quick question mate: My bike is a US import. Had 100Ks on the clock. Now has around 4000. It smokes a few seconds after start-up from cold. It's done that since new to me. Lasts a few seconds before it goes away (engine heating up). Valve seals or rings? Any thoughts would be much appreciated!

[@crosstrainingadventure]

+adventurecraig bizarre craig, no new bike should do that. sounds like valve seals but i no bugger all about mechanical stuff. :(

[@adventurecraig]

+ADVENTURE OZ No probs. I think the bike stood for about two years and the seals hardened. I'm going to pull the head and check the stems. I'll mod the carb spring as you guys did. Have a stage two needle in alread and cut the box. I like that acerbis tank. Might put one on while I'm at it! Our currency is so week at the moment though :(

[@andy3d1]

lol! At the start of the video I thought I could do this! But not a chance lol

[@AjackLee4]

I love this series

[@lifeofbryan3098]

Great video! I've done about half these mods, I'll have to get into that carb soon

[@crosstrainingadventure]

+BBQ Rider i hate working on bikes usually, but love how a bit of do-it-yourself with that carb can transform the bike.... very motivating!

[@lifeofbryan3098]

ADVENTURE OZ I hate working on bikes always! Luckily I know a guy...

[@authentic4225]

Someone posted a video of them grinding inside of the engine where that pipe is inserted. There is also a lip!

[@MothershipVideos]

What a great how to. Puts my old vids' to shame.

[@crosstrainingadventure]

+n45829 i look back on the trials series i did only two years ago and they look terrible in comparison... this video editing is steep learning curve!

[@jcee2259]

7 years after DR650 project video was posted I'm here to say none of that went on my 2008 DR650SE. Are good to go as it.

[@crosstrainingadventure]

Yep an unmodified DR650 will certainly suit a lot of riders as is. I kept my latest one untouched for a few months for warranty reasons but also to see how capable it was completely stock. But a few basic engine and suspension mods definitely transform the bike for riders wanting to push the bushpig a bit harder.

[@kriskirby6599]

impact driver works well to remove float bowl screws

[@100SpokeRiderz]

Very Cool Vid, very helpful I will be doing a buildup of my DR650 soon

[@MUCH-x4s]

I bet a crf 450 carb would work good , but I am Canadian and lazy

[@deepsouthNZ]

dont worry mate, they say worse stuff about us Kiwis, and we are the ones there doin most of the work

[@JK-ep9bz]

and the cost of $500 lol@DR Dan

[@cv8z231]

Your not Lazy your just Americans in Denial. Kiwis aren't Lazy.Theyre just Fuck n Kiwis.

[@fotog04]

Yeah,, me too...totally lazy!!

[@jasonloke2219]

Thanks for sharing, mate

[@MattLawson18]

Procycle also sells a fantastic TM40 Pumper kit if you wanna go all out. The best thing I've done to my DR!

[@crosstrainingadventure]

+Matt Lawson must admit i'm more in favour of budget mods matt... our carby mods cost $10 for a main jet andan hours work and i reckon the results are very similar to my old DR which had a TM fitted. the TM is still a bit quicker on the throttle response but i wouldn't want to pay US$520 just for that. the plug n play nature of it is good though for those who don't do-it-yourself projects.

[@MattLawson18]

+ADVENTURE OZ I tried the drilled slide, new jets and adjusted needle. I might have completely botched it up because I had a weird jump as soon as I laid into the throttle. I would give it gas, it would accel for a second, then bog out briefly and then continue to accel. I soon after bought the TM40 and that seemed to fix all the problems with the carb. Since then, I have had zero problems with it. Great video by the way!!

[@crosstrainingadventure]

+Matt Lawson i'm not carby expert but if you still had the stock needle that would create issues... i think the standard carby either needs the stock needle tapered as per this vid, or an aftermarket needle, to really work properly. a well setup TM40 may outperform gordon's stock carby mods by quite a bit but he's had trouble finding anyone with a well setup pumper carby on their DR to do a direct comparison.

[@binguskhan1]

+Matt Lawson I've had both and a well setup standard carb is just as good with a fraction of the cost. Admitted I got the Dynojet kit which saves time with the needle. The TM had a heavier pull than the standard carb.

[@dariandawson8052]

This video has helped me so much🙏

[@crosstrainingadventure]

Great to hear, Darian!

[@cryptotron]

I just did Carb modes. I saw this video yesterday, today was drilling, cutting and grinding :) By the way my first bike and my first time touching Carb, my mechanical skills on are maybe level 2 of 10. Bike feel completely different, I am so happy wit this mode. Next is exhaust modes, but bolts on header are so rusty and stuck I don't know how to unscrew them, I am scared to don't brake bolts, or maybe worst magnesium case.

[@crosstrainingadventure]

Nice work!

[@marcelcanuck]

i just finished doing these mods on my DR , without changing the muffler or grinding the header , i'm one happy lazy Canadian mate ! big difference in acceleration and much better idling ,i had to drill out the cap on the pilot jet screw on mine , (i apologize to all u climate change nuts ) , can't wait to take my pig (lol) out for ride , will have to wait until spring tho. as we have 2 feet of snow out here , Thanks Mate , i don't care what the world says about u Australians i think u guys are awesome , lol

[@crosstrainingadventure]

joyeux noel, monsieur bolduc!

[@marcelcanuck]

@@crosstrainingadventure hahaha i knew there was a little bit of french in u guys , only a french man would use an exaust pipe as a mouse calling device , lol , be safe brothers !

[@andypandy.]

nice going guys, very well set out!!

[@JoeJoeMoto]

Love it mate. Very informative, so simple and cost effective for a great result!

[@crosstrainingadventure]

+JoeJoe Moto very australian... they want US$520 for a pumper carb? tell him he's dreaming!

[@cosmiccharlie8294]

I can pick up a new 2018 650 for $5,500 usd. Think I might go for it as my DL1000A is a bit heavy for serious trail work.

[@lucasgraham4762]

Ha. The 650 is a bit heavy for serious trials.

[@doctormaddix2143]

I just checked my DRs secondary air filter and realized that half of the thing is just missing😳😳 Well good think that I already ordered a replacement and havent been riding in too bad conditions..

[@crosstrainingadventure]

I try to avoid dust as much as possible. You just never know if your air filter isn't quite in place or dust is working its way in to electrical connections etc. So whenever it's dusty I just distance myself enough from the rider in front. I'm always surprised at riders who happily sit behind other riders in clouds of dust and they (and their bikes) are just brown with dust at the end of the day. 🤔

[@dannycassell9228]

love being a Canadian, although I prefer calling it working smart, not being lazy...lol😁

[@crosstrainingadventure]

So true! But I love poking fun at Gordon lol

[@tigercs1]

Buy DR650. Replace - seat, fuel tank, carburetor, exhaust, front and rear shocks, front and rear tyres, headlight, speedometer, handlebars, air filter, mirrors, bearings, footpegs and magneto. Oh yeah we forgot to tighten a few screws that might mangle your engine aaaaaaand 3rd gear might fail. $9000 AUD new usually gets you twin cylinders, water cooling, ABS, fuel injection, colour dash with fuel gauge + tach, slipper clutch, LED lights, 6 speed gearbox and a windscreen. Not here buddy. "DR650 best bike ever" Haha. Yep. I still want one.

[@cawalther]

I'm in the US and I really like your video. Many great points. I used a 1/4 drive with a #2 phillips to break loose the float bowl screws (I know it's JIS) ;) That took nothing compared to all my might just prior. Also replaced with hex bolts. I'm mainly commenting because I'd like to know how the bike ran after your needle taper and shelf shave. From what I understand, the tip is more "open throttle" and the middle flat taper is more low throttle/less fuel. You've also dropped the needle substantially with the shelf shave.. so less fuel, but thinner taper. but I'm guessing the snorkelectomy and new hole helps with the rich taper. Complex relationship there... Thoughts? Mainly, how's it run?

[@crosstrainingadventure]

+Chris Walther as per the vid chris more power across the revs, more economy IF you don't use the extra power, starts easier. all good and no bad. :D

[@nealtoner7875]

I dont wanna polish your balls but I have to Say that so far I'm completely hooked! (pun intended!) can't wait to see how your porka turns out.... Subbed and Much love from Yorkshire

[@crosstrainingadventure]

cheers neal, the whole DR650 series was finished ages ago on this channel. we also did a video or two about the finished DR on our enduro channel: kzbin.info/www/bejne/iHKTg2Zte9N_m68

[@brandtagone8487]

Hey that would make us guys up here down under

[@Kaegis]

I did similar to my DRZ400E except installed a JD Jet kit. Went "acceptable" after that.

[@Kaegis]

@Der Wuestenfuchs It made a massive difference and much smoother. Heaps more torque across the rev range. Lifts the front wheel much easier.

[@antzontoast]

Once you get enough experience on that DR I may let you work on my XR650R hehe

[@tangledline]

These are REAL mods!

[@simonbertioli4696]

Really an excellent video...and very well presented ....However..do you have any videos on the Kawasaki klr650..in the similar vein... Reason..l am thinking of buying one 1990-2003. But also did look at the DR650.. Was after the larger tank..as have distance to travel..

[@crosstrainingadventure]

There was a link at the end of this vid to the info you are chasing kzbin.info/www/bejne/bV63iGeXhLWYjNk

[@ryanlynch2259]

Just make sure you use a metric screwdriver working on the carby!

[@crosstrainingadventure]

yes, that weird JIS screwdriver! what would it cost them to change over to allen head screws.... five cents?

[@jcee2259]

No, not me. I want exactly what I purchased in 2008. And it is still serviced every two thousand miles. I purchased it to assist my Pacific NW speleology.

[@brandtagone8487]

The dealer I purchased my bike from fixed my stock carp issues by simply drilling a plug (sorry can't be specific cause I am not a mechanic) and I have no issues with it 11,300 miles later. This of course did not increase power as your mods did. I am hesitant to mess with any of this as my bike is so damn fun to ride now but if this changes your mod will be the first to try

[@brandtagone8487]

+brandtagone oh and thanks think I'll go clean my breather

[@crosstrainingadventure]

+brandtagone i certainly had fun on the DR for those first few rides without the power mods and there's nothing wrong with leaving the bike as is. it does start easier and get better fuel economy too with the mods but plenty of guys ride them as is.

[@brandtagone8487]

+ADVENTURE OZ Would love to do all the mods, in time. Right now my next mods are suspension and pipe. I am not a mechanic so messing with carbs and the like, I will wait till there is an issue. I just finished per your video the breather and fuel filter. I am following your series closely and look forward to more!

[@brandtagone8487]

+ADVENTURE OZ Ok you got me muffler and carb being done unfortunately my dealer was no help on the gsxr so I went with the fmf at procycle. No need to reply and thanks.

[@brandtagone8487]

+brandtagone Installed the muffler and did the jet kit from procycle and gotta say glad I unleashed the beast!. Your video was a great help on the carb and grinding down the pipe weld. On to the cogent front, Thanks

[@noelbentley5204]

I have been watching your vids for a long time - when I am not laughing I am enthralled with your excellent coverage of the DR650, a truly majestic bike that you can rebuild to whatever standard you want. 2 questions - firstly if I was to grind out the lip inside the header pipe, would I need to change the needle/ settings in any way? I have done all the carby mods you cover in this vid and have a Stayintune muffler. Secondly, what are your thoughts on using a broad band oxygen sensor to get the best out of the tune up? Would it be worth the money (

[@crosstrainingadventure]

I've never seen anyone dyno the DR650 to see if grinding that lip makes much difference, Noel. I didn't' actually do it on my latest DR650 and the performance boost seems about the same. Remember that grinding also weakens the pipe a bit so it's more likely to break if it hits something. I've never even heard of an O2 sensor. The stock BST carb is very forgiving when it comes to getting things a bit wrong, I doubt the sensor would make much difference, if any.

[@wipperwils2111]

5:40 they’re not Philips screws, they’re JIS (Japan Industrial Standard) which. Buy a JIS driver and they won’t strip.

[@crosstrainingadventure]

Believe me they are often loctited so severely at the factory that even the JIS won't budge them.

[@wipperwils2111]

5:58 - DOH! Wipperwil should zip it - LOL!

[@SineOccasu]

wtf is with all the Canuck hate m8s haha. Great, informative video. I went the FCR39mx route, and absolutely no regrets. That carby chirping tho. You just don't get that with the stocker :D.

[@crosstrainingadventure]

+SineOccasu gordon actually said to make sure i give his countrymen a hard time when i put the vid together lol!
