DR650 790 installation review

[@planemanx15]

Thank you for the compliment. It's actually a seat off the DL1000 (Suzuki v-strom). I was able to make it fit nicely and it's far more comfortable than I could ever get the stock on Sargent seat. I use my dr for a lot of 2-up travel and very limited off road, and the DL1000 seat is great for it. I will update the video later this season, and a review of the bike.

[@700shabatt]

Wow that's a huge task ! You gotta be proud of that. Great video.

[@planemanx15]

Thanks! I am proud of it

[@piramabatx]

few hp?

[@strictlystreet1517]

@@piramabatx I believe my 790 puts out 53Hp if I remember right. Much better than a stock 650

[@planemanx15]

Well worth it, Even with really high gearing, its still a torque Monster. It vibs less, and pulls strong even at highway speeds

[@paulmontagner6360]

Concidering a Honda 750 x4 road bike had 4 cylinders youve got 790 cc in a single thats huge for a duel sports bike

[@DustySquitoNM]

So, so awesome. Definitely need to get around to doing this mod on my DR.

[@strictlystreet6560]

I was just given a $1,000 estimate for the 790 big bore on my DR650 can't wait I hope it's worth it

[@planemanx15]

It totally was..

[@AKaliforniaKing]

Thanks for taking the time to document your project. Well done.

[@SuperOrcy]

this is my plan for my DR if I ever need to do a topend rebuild. at the moment, it serves my purposes as a stock machine.

[@IRQ1Conflict]

You must be proud of that accomplishment! Nice bike and good job on the install. I guess most people that are at least a little mechanically inclined could do it it with simple tools and not much problem?

[@planemanx15]

Yea Im really happy with the way it came out. Most should be able to do this project. There is a lot of support forums for the mighty DR so its very easy to find information.

[@louiewatson9389]

If you got oil coming from the spark plug washers, you have shot oil rings on your piston and it's fouling your spark plug and valves. You needed a top end rebuild for sure then. If not, it was more than likely the valve cover gasket.

[@Sum4Seb]

Saw that kit on Procycle's website! Still drooling over it... Hoping that one day I will be able to get that on my DR. I know it's an older vid but good job on the install. If you still have the bike you should post some riding videos to see how the 790 kit performs :) *T4S*

[@planemanx15]

Thanks for the comment. The procycle kit was awesome. I still have the bike and it still puts a smile on my face every time.

[@mikeschlup4164]

any more vibration?

[@strictlystreet1517]

@@mikeschlup4164 nope not on my big bore build

[@Nostrildomus]

Yea Mon . You bet ya , yep and yea haw . A side note though . When your on the starboard side the port side cylinder head gasket let go causing that lean detonation during the pull . Sure can cause bottom end problems if left unchecked . Thanks

[@user-ev1sz6kg1t]

Nice work, would be interesting to hear how the beast goes now and if it was worth it ??

[@BrandonRa]

Was the reason it wasn't starting the first time because you didn't have the gas tank installed? I was thinking to myself " it has no gas supply"

[@dualsportdaniel6445]

He has a breakdown of the installation here: advrider.com/index.php?threads/dr650-790-big-bore-installation-and-review.860980/ He said it was a combination of running lean, WD40 etc in the engine, and possibly no fuel at all.

[@ignaciocanepa6233]

nice work! are these bikes (stock) coming with replaceble cilinder sleeve? which is separated from the cilinder itself? or that is a 1 piece only? thanks

[@JB-uo9qo]

I want to do mine, but I wonder if you should change the Cam & the Cam chain tensioner also. Already have a cut box, pumper carb, X40F0X exhaust & acerbis opaque tank. After this I might wante to screw with the suspension.

[@homunculous007]

Nice Video, What seat is that? Please update this video when you have a couple of thousand miles on the new setup. Thanks.

[@st2816ven]

I want one. How does it go?

[@josephsaia5527]

Do you know if the DR Big 800 motor is similar to this kit?

[@MrSpoonR1]

Good question ! I ask me the same ! 😅

[@squintela]

I whish there was similar for pre-96 version. Only a 660 cc available for these old pigs...

[@NichtskoennerTV]

Great Work ! I would like to see a Face from a Lc4 driver at a traffic light ! :D

[@joejava68]

Your starter sounds as crappy as mine does. I will go through with it soon.

[@MrVeggis1964]

joe mac Me too....Are you gonna restore it by greasing it up? I think there is a howto clip on yt...

[@CraftwerksMC]

OK video but learn to turn your phone on it's side. HD is widescreen, not tall screen.

[@dukegnarley]

I drag raced a 650 adventure on my stock DR and just barely won. 790 kit is next.

[@SteveThurmond]

great vid and build. i'll be referencing your thread quite a bit as i'm about to undertake the same 790 conversion as soon as everything comes in from ProCycle. quick question...did your brake calipers come in red or did you paint them or purchase them aftermarket in that color? i'm going with a similar red/black color scheme, so just curious.

[@planemanx15]

Thanks for the comment... I painted my brakes with caliper paint.

[@SteveThurmond]

planemanx15 thanks for the reply! great! much cheaper that way. I plan to rattle can a lot of parts...going to pretty much black it out with anodized red accents. you still have her?

[@planemanx15]

I do! She's sitting unused right now due to all the snow in the northeast. I can't wait to start riding again.

[@timthepartypimp]

[@phrankus2009]

PLEASE! What model and year VSTROM SEAT did you put on the DR790 ?? Was this a "high" seat or a "low" seat ? ... Did this require any mods ?

[@planemanx15]

I got the regular dl1000 v strom seat. I had to cut the bottom of the seat pan to fit around the battery. I also added brackets so the seat can bolt onto the dr frame.

[@phrankus2009]

planemanx15 Oy ... I might just rebuild the stock seat or go with a Sargent, et. al. Thanks for the reply.

[@deepsouthNZ]

how is the fuel economy now? much of a difference?

[@planemanx15]

Fuel Eco stayed the same

[@billbonu1639]

That doesn't sound good at all.whats all the clanking and pinging and tapping noise about?

[@TheGeohart]

did you have to have any machining done, or did this kit come complete

[@planemanx15]

the kit comes complete

[@franciscoernestolozanmijar6308]

Hello friend.. How do yo make the stand bar for dr650? Is very good!

[@planemanx15]

I bought a kit from motech

[@Oxenan17]

turned out pretty nice. at first when I heard that oil in the cylinder head thing I was like damn this dude going to mess it up... but seems like you did well, obviously lubricated everything well before assembly. you maybe should have cleaned the combustion chamber and had the head checked, that's what I would have done at least but it's okay.

[@planemanx15]

Yes this was definitely a learning experience for me. This was my first time rebuilding the top end of a 4-stroke. Lessons learned. The guy I sold the bike to is selling it now with over 10,000 miles on the rebuild.

[@Oxenan17]

+planemanx15 you always learn something new when doing these things. I have a long past with these engines but still every new engine is a new opportunity to learn! I have a DR myself, I bought it from a friend of mine. Piston is blown to a million pieces, the guy who sold it to my friend was not as succesful with the rebuild as you. Great job done here and for a first 4 stroke rebuild this bike is definately not the easiest.

[@Bush_Tucker]

@@Oxenan17 this bike is probably the easiest four stroke rebuild you could do it's a big air cooled single with a single over head cam it doesn't get easier then that

[@MrSlickington]

So, was the oil in the cylinder head bad?

[@planemanx15]

Nope! Should have figured since an oil line runs to the head! Stupid comment on my part.

[@seanstrickland4970]

I'm curious.. what did it top at?

[@planemanx15]

Around 110 on the track.

I just saw a video of a guy who rigged his DR650 with after-market Electronic Fuel Injection and, I am kinda thinking ... Why not just get a V-STROM DL650 ? ... Anyway ... I *WAS* considering investing in a used KLR but the DR650 is much lighter and is air-cooled and carbed so ... About as simple as a regional touring enduro can be, mechanically.

[@SnakeManQQQQ]

this is water cooled or oil ?

[@planemanx15]

+SnakeManQQQQ air/oil

[@louiewatson9389]

You definitely got the timing wrong on the first attempt. Lucky you didn't bend any valves. I hope you set your valve clearance with the engine cold before you started it.

[@planemanx15]

Louie Watson timing wasn’t wrong at all. No valves were bent.

[@Diddilydoodily]

if you have to ask some one if oil in the top end is the norm you should have had some one else rebuild your bike.

[@planemanx15]

Diddilydoodily thanks for the advice bro. Really appreciate it.

[@EnduroIceland]

How many hp?

[@planemanx15]

Should be just over 50.

[@louiewatson9389]

Yes, you are supposed to have oil in the top of the head... The valvetrain is lubed by engine oil... Not much of a mechanic I can tell.

[@planemanx15]

Louie Watson first time inside an engine. Everybody starts somewhere.
