Aww man can’t wait to see you rip this one

I want to say love your work, The only suggestion I have, I ran my own small engine shop for 10 years, and whenever I saw a bent valve on a head and had it broken down as far as you have this one, I always marked the valves as to their location and removed all the valves checked the springs hight and decarbonized everything with a soak and brushing in Seafoam and then hand lapped all the valves to the matching seats, and I also checked the head and cylinder surfaces for square and flatness, before reassembling them and of course all new high-quality gasket sets and new valve seals always. But you do a good job brother.

can’t wait for the first ride

Someone is quite the artist with stick figures on those radiator fins. 🥴😉

That must have been the best feeling ever. A few months ago I bought a non running polaris predator (finding parts for this atv was ROUGH). Cleaned fuel tank, repalced petcock,fuel lines, sparkcap, battery, spark plug, fuel pump and carb still wouldnt start. messed with it for an hour and realized the grounding cable from the battery just wasnt tight enough. tightned it, got it running and sold for a $2000 profit. I think i wanna get a fixer upper raptor next! Great video thank you!

Very nice I knew you were gonna have it running in no time, I could just tell!

So winter is coming and I need a new project…. Might get me a fixeruper .. 2vintage gives me the bug! Great videos man!

Good work man loving the content

awesome video job well done 2vintage

A trick to start anything without the carbs is just spraying starting fluid in the entrance to where the carbs would be just dont to a ton because it will want to rev up extremely high

Love your vids bro. Keep it up👍

Awesome video man keep up the great work

🔥🔥🔥 video can’t wait for the next one

Good job! Sounds good. Fresh oil & filter change much needed .

Cool been waiting for this one

I've had my 2001 since 2007 I never ever use the parking brake so one time years ago the parking brake switch got bumped just enough to activate it and tried riding it and it would not rev out just bumble at low rpms, I was baffled pulled the carbs (pain in the ass every time) and nothing ....then I see the little lever pulled out a little bit I pushed it in an wabahhhh it was back. I was so happy and discussed at the same time. I does not take much to make a 660 wake up from its fairly docile rider friendly stock form. Mine has a hot cam (stage one I would think but not shure) big gun headpipe, R4 silencer, air box mods with k&n filter, and a DynoJet kit and it flat out rips for those few mods.it will walk right away from a stock 660 with just a slip on. I also went -1 tooth front and +2 on back and a set of 18" on back (20" front), it dropped top speed to around 60ish from 80ish but it gained retarded acceleration and snappiness, hardest part is keeping front down when it hooks. Unless you desert or road ride you don't need an 80mph top end. You can shift as fast as you can blip the clutch bam bam bam, pretty wild for sport wheeler, these guys that say "my 450 will dust a raptor" are full of crap 450 MAY edge out a raptor in a drag race but it won't "dust" it. I've seen plenty of videos where there neck n neck and even after switching riders.... The raptors definitely have more Tq but they are 50lbs heavier and power curve is waaaay different. It's apples to oranges 2 very different machines for 2 different purposes but both are fast and both have there pros and cons. I will say Off the show room floor a 450 is definitely faster.

always amazing uploads

Absolutely love videos like this any kind of quad or mx bike that's up for spares or repair here in the UK goes for stupid money and there's not many about at that thanks for the videos 👍

This is gonna be sick

Congrats! it’s hard to believe the 1st jump box didn’t produce enough amps to spin the starter effectively. this seems like a big Win for you & didn’t spend extra time chasing Gremlins or non-issues. that 660 is gonna rip, Dude!

Great job man she fired right up

You deserve a lot of subscribers and a lot of views ... keep up the work ... eagerly waiting for another cool one... 😎 Cheers ...

Great video man

Love these videos

Another good one joe joe cant wait to get my dual intake and exhaust grizz motor thumpin

Those pins* are called collets btw

Another job well done 👍🏼

Love watching your vids 🤘

your work ethic is reat alot of people would all pass on the stuff you buy and fix or pay the dealer to fi

I just picked up the exact same quad for 1200 bucks and thus far it only seems to need carbs rebuilt and a starter solenoid, ill be checking the compression Spark and doing an oil change next week.

Awww man you’re lucky for having so many dirt bikes and 4 wheelers I’ve wanted one my neighbors have one and they look like they have fun riding them but love from South Carolina 💙

Awesome video bro🔥🔥

Looks like a kid made a stickman drawing with the radiator fins.Lol...

Another great video. Sounds like you have a lot of cicadas there lol

A harmonic balancer puller for automotive use would pop that flywheel right off with the 3 bolt mount pattern.

You certainly have way more patience then i ever had

RIDE THE Z400 please, love your videos!!!!

The radiator has a stick figure man drawn on it lol

You should just sit the tank back on rather than messing about with easy start all the time , good job on getting it running 👍🤙

Thanks for this

awesome, that other chain was pretty loose! same issue i had on the modded 660, dang thumpers lol

Great video, love it when a plan comes together. What would cause the cam chain to stretch like that?

Great job brother. Wanna run it against my 800 outlander xxc? Hehe

congrats

Posted just 24 minutes ago!! Haha just got down watching the first video. They help alot.. rebuilding my Yamaha RT 100 thanks

my raptor did the exact same thing when i first bought it... wouldn't start off a jump from a truck but stuck a new battery in it and it started right up lol

That's a 2001 1-way bearing assembly if you to replace the 1-way assembly go with the 02 03 assembly i believe 04 05 1-way assembly bearing and flywheel are different

Good job

You should make merch that says “found the culprit”

Like your videos help me learn a lot

You are quad saver ✌️

hell yeah she sounds good

You need a 40x60 garage dude..

It's ready for 686 kit, jugs off half the battle.

Either your neighbour is a dentist or you have 10,000 crickets in the garden. Good stuff tho 👏

Use a wire hanger on the frame to hold the timing chain it will save some heartache

Great repair! What brand chain did you get?

That big block piston

Hey man, awesome video. Weird question, is this your full time job and do you make enough to support yourself with just RU-vid and flipping bikes and quads?

You baddazz bra

Keep up with ur vids do more 2 strokes

What do you like working on more? Quads or dirtbikes

I know it doesn't matter now but I think you missed the slight kiss the piston made with the value. You can see it in the first video.

I just put a big bore on my raptor 660 and the timing chain dont want to go over the camshaft.the chain is half way on it u dont think tht its stock and thts wht its not letting it go over it

Very fast 💨 🥰

Dont give it that mutch gas when starting. Most 4 stroke carbs have a jet that squirts fuel into your intake. So everytime the throttle opens fuel shoots into the intake, this way you could easily flood your bike. Just a tip for next time.

I admire your work ethic but I can't understand how you could remove the cylinder and not replace the rings.

Should never, ever put any new engine part in the chuck of a drill, especially a new valve. The slightest burr on the stem could damage the valve guide when you install it. Glad to see all these old bikes revived though!

You should ask those cicadas to be quiet down while your filming.

Awesome vid Brother thank you. What model jumper pack do you use, mine works once on a car and a couple on my OHVs and bikes before dead. If yours is better, please share name or link lol Thank you either way my Friend. Be safe :)

That mark inside the crank case is probably where the chain nearly came off the cog and got all the stretch, but mad that the valve didnt crunch the piston crown.....or did it?. The problems with bike shops is they never want to do the short fix it would have been all the valves need changing or re seating , all new springs and seals, probably would have put a whole new top end in also (just to be safe ) and the bill would have been about $2500 minimum.

Nice.

Wow I have seen them stretch by but that's looks alot

Nice work bro.. wish you live closer to me so you could come to my place an rip it... I will be uploading a vid of my 2005 660 and my 2016 yz450f.. an yeah told you the 660s are easy to work on..

That bend valve looks like my dads rear axle

I think you should build yourself a bench instead of working on a piece of cardboard on the floor, or go too a school auction and find yourself a heavy duty teacher's desk. They work really great

The jug bolts are different lengths

Already know the plan for the rm125?

Could you do another DS 650??

Just bought a Polaris 500 for 1500$ needs a little work though

If you buy all that parts, are they specific for that model and make of the quad or is it mostly 'universal'?

Stick Figure great band!

@Whoop!!

Well lookey there . It’s raptor happy hour . Nice thumper.

Lmao, they drew a stick man on the radiator

Why in the world would u not put new rings on while u have it apart that’s crazy bro now whoever buys it will have to tear it back down in no time to replace them..

Is it just me but didn’t anyone see the radiator has a smiling person

When's the garage tour

Is this the same engine as in a xt660?

I have a 2001 Yamaha raptor 660 if timing an valve clearance is good. Wondering why my raptor has a hard crank. piston sounds good with no spark plug inn. Engine get hard to turn over with spark plug inn any idea what’s wrong with it?

Is it worth buying a Yamaha raptor 2006 660 cc

Is there anything you can’t fix?

Why didn't you just replace all of the valve seals? ... and lap all of the valves? ... as long as you had it tore down that far?

Sounds like that thing was run at high rpm for a long time

My Honda 650l hates low battery also No start Or bump start it’s tall for me

Who the hell drew a stick figure on the radiator?

Does anybody else here weird background noise I've only been hearing it for a while you might need to change your camera you are using but other than that the video is great

👍👍

At this point i would trust you to rebuild my engine!! Just some advise when you have a bolt that's snapping as you're torquing you should loosen it back up and lube it because it's not the correct torque when that happens!! Great job though!!
