Yamaha 660 Raptor Rebuild

Afterwards my success with the Blaster projection, I decided to effort a rebuild on a quad that was potent from the start to see how I could amend information technology. I shopped around and found a dainty deal on a 2001 Yamaha 660 Raptor. This model has some known issues, so I quickly put information technology to the examination.
Before replacing several major components, I bankrupt something just most every time I took it out. And information technology bankrupt me a couple of times, too. When I sold this machine in 2006, though, she was a strong one.
The kickoff 24-hour interval at habitation, I took it for a spin and found out that it sabbatum too high and narrow for the flat rail. I broke iii ribs finding out how easy it loftier-sided.
Installed a lowering kit and fabricated a relocation mountain as I wanted to keep my head lights.
In lodge to keep the prophylactic side downward during while turning, I installed wheel spacers for a wider stance.


Starting time await at the quad with brand new Pure Sports Bandit Flat rails tires on ITP T-ix Pro wheels. Air-conditioning forepart Bumper, Rear Grab Bar, and Stickers added.
Discovered two known issues at this point: 1) Second gear is gone and 2) the clutch is on its mode out. The 2001-02 660cc Raptors are notorious for blowing second gear. Having to employ a gear that's too high for reverse is difficult on the clutch.
Took the engine out and someone borrowed my front bumper.
Cases split.
New Wiseco Hot Rod Crank Kit installed.
Old transmission with the new 2003 gears installed.
I did some head work, calculation new titanium valves and retainers with upgraded springs to a new Hot Cam.

I had a adept friend, Larry Zumbrun from LZ Racing, do a porting job. He'due south the all-time top-stop guy around. Larry put together a New Wiseco racing piston in a newly bored sleeve. I made a few other modifications to the engine and transmission and added a new clutch basket and Hard disk drive clutch disc earlier putting it dorsum in the chassis.
Wait closely and you can see the absurd, new exhaust working its fashion around.

After calculation a new Scorpion exhaust, she's ready to whorl! Awesome-running machine.

Here she is showing off her under carriage with an Air-conditioning rear sideslip plate and nerf bars, a GYTR frame, and A-Arm Armor.

As well added some trail-riding, general purpose tires – 22-11.00-10Maxxis All Trak in the rear and 22-vii.00-10Maxxis Front Pros up forepart. They are all mounted on ITP C-Series Cast polished wheels. Oh, and more stickers. Doesn't she look mean?
Ability Madd Mitt guards help to go on the grips clean. And more stickers.
Moose shock covers, GYTR frame protectors, DG coolant and brake reservoir protectors.
A ameliorate wait at the clean Scorpion Frazzle with an FMF sticker (just considering information technology looked cool, and surprisingly never melted off).

Trail Tech nuance board and Renthal bars with a tethered kill-switch and twist throttle. The little red thumb lever in forepart of the throttle was a quick opposite switch.

Set up to go serious. Looks proficient, doesn't she? Take a long look because it's the concluding fourth dimension you'll see her this clean.
Lock and load – going riding. Hatfield & McCoy, here we come.
Home-sweet-home, Westward Virginia. Hatfield & McCoy Trails Heaven is the all-time place I've always had the pleasure to ride.
Making her earn her keep.
This hill is a lot steeper than it looks – out of our group, just 2 of us went to the top.
Nosotros made it and here is a pic from the top, looking downward at this beautiful country.
I didn't quite make information technology up this coal loma, only the tires started spewing coal downwardly the hill. When I got off, the front end was tilting back, then my buddy Ken held her downwardly while I took a moving-picture show before climbing back on. These pictures never look every bit steep as being there.

Another groovy affair well-nigh Hatfield & McCoy is they permit you ride all over town. Here nosotros are gassing up the quads and getting some grub.
Easiest and cheapest mode to clean your quad before loading upwards to go home.
This photo is from a winter ride at a buddy's hunting lodge in southern Ohio. Blew out my rear end on this trip! On the quad, that is.
Cold, muddy ride at Haspen Acres in Indiana. Burned upwards another clutch and broke my rear fender mounts from the weight of the mud. It took me days to get all this mud off.
