FINALLY Figured Out The BIG BORE Raptor 686! (INCREDIBLE POWA')

[@SQUARE1SpeedChannel]

Can't keep the front end down, then just pass him in a wheelie. "Modern problems require modern solutions" 🤘

[@StupidFastJohn]

Lol PERFECT solution man! 🙌

[@idriftgodly3299]

+2 A-arms , and front suspenison will keep the front in contact . And also improve braking geometry

[@leejennings173]

Appreciate everything you and Sabo area doing for quads… it’s greatly appreciated by us sport quad enthusiasts. Keep it up!

[@StupidFastJohn]

Thank you Lee!

It's gd to see that the older gen still become a big kid when ur on a sport quad. Damn I can't wait to watch quad wars it's going to be great . N u.drove that R like u stole it loved it

[@manaaalsuwaidi3643]

Hell yeah! I remember back in my high school days when 660 was first introduced by Yamaha and how everyone was going crazy about it! And i was on my little LTZ400 😁 it's awesome to see those machines still around and still kicking bts strong 💪👌 great work guys!! 👍🏻👍🏻👍🏻👍🏻

[@Davido50]

40 somethings the older gen!? 🤣🤣🤣

[@StupidFastJohn]

Yall are harsh im not even close to 40 🤣

[@brainstain22]

Really happy for ya man...I've been fighting a quad for a friend for the past 3 weeks and just got it going today. Chinese carbs = caca. Put a true mikuni on and bam...runs strong. Can't wait to see this torque monster rip.🤘

Kicking it here in the UK nighttime. Saw the post any thought this be good. U and Mike I like your style ...

Had an 08 raptor 700, blew it up , rebuilt it 105 bore + 4 stroker etc etc kept pushing , even had it spinning 12k rpms in lower gears for awhile , which eventually blew it. Dropped the piston right threw the cylinder wall. Skipped the headache , chopped the frame and stuck a 08 suzuki gsxr 600 motor in an called it a day 😁

[@dennisbrooks186]

Hell ya bro!!! She deff looks like she romps!!! Idk man I still haven't decided which team I'm going for. Gotta decide soon 🤔 nice job bro!!

[@StupidFastJohn]

Ty dennis!!

[@yenko3378]

Hey one thing you can do to help with your launch and keep the front end down try stiffening up the rear spring it will help keep it from squatting as bad which causes the weight to shift backwards on take off. The raptor is sounding good man hopefully no more issues and good to go for quad wars

[@Issablue5.0]

How do u do that I always wondered if that was possible is it like a twist mechanism?

[@ononewheel7]

You need to grab a lift table from harbor freight! The 500lb table is cheap and your knees will thank you and you will be much happier working on these quads 🤘

[@travisburger8681]

Hey John how do you have your carb setup for the 686. I have almost the same setup was just wondering adout the main jet and airfuel mixture screw for the zoom zoom carb? Was going to put dyno jest in it?

[@jangoreo]

No locktite or torque on the starter clutch bolts ? Brave, also amatuer

[@StupidFastJohn]

An impact gun isnt enough? 🤷‍♂️ thats how many of the big dawgs do it....

[@goldenwheeledbanshee9160]

U put the BOOM in FAST. That raptor sounds wicked. I see 2nd gear launches in ur future and plenty of fun.

[@StupidFastJohn]

BARRY! Thanks bro! Im not a huge fan of second gear launches but ill def give er a try 👊🙌

[@Savageiq1bc]

What kind of header and exhaust did you go with on this raptor?

[@FarmerBrown420]

Had to pause the video to check my vision when the impact started going off

[@andrewsomers1909]

Amazing job bro, she can get up and go, thats for sure!

[@DIGGINGDEEP007]

What starter to you upgrade to? I didn’t see the link. I have a 686 big bore that is hard to start do to the high compression. The guy I bought it replaced the starter and I just fried the one I threw on. Thanks!

[@StupidFastJohn]

Oem is the only way to go!

[@kingkracker1998]

man I tryed so hard to get out to badlands to ride with ya guys, I wasn't sure the days u guys were there, so I went Thursday! lol. John u said u would be there all day Fri thro Sunday, but I figured u guys wouldn't be riding much Sunday. and I couldn't get out there on Saturday, just had so much stuff to do and all my gear and quad was still dirty from Thursdays ride. and I just can't take a dirty quad to the park! so I went back up there on Sunday and I swear I saw u guys leaving as I was pulling In! lololol. but it's all good, I had a fucking blast both days. meet some cool guys to ride with both days. fucking love that place. such good riding. didn't spend to much time in the sand pit, I was cruzzin the trails and the creek. that's gonna be my main riding spot I think. but I was hyped to ride with u guys, wish I'd a cleaned my quad Friday O well. shit happens! maybe next time. I'm super hyped to see ur vid from badlands. hope u come back soon.

[@schons77iceman]

Whats your plans with that eclipse.. I wanna see you rebuild that dsm

[@Kevin_Yagoonie]

Would you happen to know what size rear tires you have?

[@roguepowersports3576]

Nice to see it up and running again. Did you have any reverse issues with the rev limiter? My 660 is being a shithead with reverse. Also what did you do to run the fan? Raptors are known for having great cooling and Apparently the fan don't run much unless really hot. Just curious on how you delt with the fan and if you had reverse issues.

[@gordonwbell]

Hey man, do you mean your reverse limiter is kicking in? You can google hard wiring it to remove it. Also, My fan runs all the time because the previous owner used to race it and wired it to run all the time, it’s the thermostat at the bottom of the radiator that turns it on.

[@rocknraptor3195]

Awesome👍 team raptor 💥💪

[@stretchnnuts]

Built my raptor the same way other than I have the big gun evo r pipe snd headers. They are nasty

[@ls2005019227]

So; your issues were a missing needle bearing, the one-way bearing, & carb jets? Glad to see you've got it back in action. Sounds great! I've been especially interested in your build, as I have a 660 UTV apart in my shop at the moment (timing chain came off). Not sure if I have a tensioner issue, guides, or stretched chain. Any way to measure that? Great video & thanks for taking us along.

[@StupidFastJohn]

Thank you for the feedback! The tensionsers on there are notorious for failing after awhile! I actually drilled mine out and thread it to become a manual tensioner. While your in there may as well change the chain for cheap insurance 👊🙌 if u wanna send me some pics on my instagram ill gladly help more! ✊

[@ls2005019227]

@@StupidFastJohn - Thanks for the reply & the help. In looking for parts, I had seen those manual tensioners.....I can buy/build one easy. To get the correct amount of tension, do you simply adjust the bolt until it touches? Any idea how often you'd have to readjust? Thanks again!

[@andrewgiske5494]

your welcome bud

[@kacperburzak1610]

To keep the front end down you might want to change the gearing from the engine to the wheels and like my friends did on their moded blasters which picked up the front end they put 2 red bricks and tied them to the front and it was a bit better

[@StupidFastJohn]

Bricks hmmm 🤔🤔🤔

[@kacperburzak1610]

@@StupidFastJohn yup might seem stupid but it works xd they do enduro with 40hp blasters and the front end keeps going up so they tied 2 bricks to the bumper

What state are you in? Looking for jetting refrences for my 686 big bire 03 raptor. Im in GA at like 900ft elevation. I bog hard from 1/2 to full throttle

Pa, I had to drill my pilot jets because they did not make the correct size. Your main jets I would probably run around the 160 range both of em same! 👊

[@caleb7194]

I was looking at the 686 and the 693 which one would you recommend?

[@StupidFastJohn]

If the 693 is a stroker and you have to put a crank in i would go 686 because its just a big bore

[@davidblum_]

If you really need to keep it down so it won’t wheelie you can buy a lowering kit for the front for under 40$ which will help keep it down

[@dakotahicks6725]

Did you upgrade the second gear set that's one of the first failure points in the Raptor 660s especially once you add more power

[@StupidFastJohn]

No because that was the 01 and 02's the 03s they fixed it 👊

[@dakotahicks6725]

Wasnt sure I had an 02 and about a month after getting it was riding around some curvy uphill trails came out of a curve going up hill hit 2nd and guess it stripped the gear and lost second

[@earlgunman6325]

Yep...time for her to hunt. I am a little bit worried that the Predator will have an advantage when it comes to keeping the front down. Definitely a bad ass Raptor.

[@Dubsspeed]

I'm confused why people have so much trouble with Chinese carbs. I mean yea buy the cheapest one and of course itll be a roblem from the start. But if u get one thats not stupid dirt cheap, and once u get it take it apart and really make sure everything is clean, and jet it accordingly and install the correct needles in it u won't have issues.. gone down that road multiple times. It's all about the prep and setup man.

[@matthewm3965]

Maybe you can put a weight or two on the front of it to keep it down🤔 but I love it man and I say you should keep it dude it's great content and it would be sick if you could race it against the banchee some how

Lectron carbs work better for drag racing applications. They are great for wide-open throttle. Not good for trail riding or casual riding. 😕 Just my opinion but I'd say just get a pair of mikuni carbs.
