the only problem i have had with my raptor is the parking brake. it will need to be adjusted. it squeaked when i was riding and didn't hold when i set it. i heard that this was a common problem with yamaha's new parking brake lever. i took it back to the dealer and he set it up for free. no problems now. only i hate that darn reverse. you have to pop the clutch to get it in and out. but mine is an 04 don't know about the 01

 

We are all talking about the 660. As far as I'm concerned, you're still riding a pretty warrior.

If the 01 tranny is bad you need to replace all of it with 02 components. If you just keep the same trans it will probably go out on you again. Raptor tranny has the instructions and links to the parts.

Other than that, the 01 subframe was square aluminum tubing and stronger than the 02 and on round steel subframes. The rear shock mount is a little different too.

If you put the quad i neutral before you try to start it, your one way will last forever. Too many people starting in gear with the clutch pulled in. It possible, but its not good for the bike.

I believe the rule is that if the 01 will cost you 1000 dollars less than a comprable 02 or newer than you should get it. Thats if the trans is bad of course.

 

And as far as the parking brake for any yamaha, remove it and install a block off plate and new clutch perch.

 

have a problem, i own a 01 raptor. i recently upgraded the tranny and put a piston in myself. at first it wouldnt run. I figured it was the carbs so i bought a rebuild kit with all the jets and everything. now it runs, but after running it hard through the gears once (1st through 5th) it cuts out and wants to die. So i figured i wasnt getting enough gas to the float bowls so i drilled out the gas inlet on carb 2 and added a 2nd fuel petcock and line. Still happens, the floats are adjusted right and everything. It will run fine unless run at high rpms for a while, but just like trail riding it usually doesnt do it even if im hitting the throttle. i even was riding on ice one time just barley on the throttle and it happened. One time it died and i checked the oil and it started pouring out and it was kinda grey like some water got into it at some time. But then i rode it home at low rpms and checked the oil and it was right where it should be just a little lowbut still grey of course. Its like every time it dies the oil wants to pour out. i was wondering if the oil flow was restricted somehow. I didnt take the oil strainer off when i replaced the tranny (anctious to ride i guess). does ne one think that the oil pump could be holding the motor back. could it be that the pump was straining to pump the oil past the restiction. Any more ideas, its got good compression. Also i have a dynojet kit and airfilter. It does knock a little if you bring it up to about 5000 rpms and let off it will go ta ta ta ta ta ta ta and then stop. PLEASE HELP NOT TAKING TO SHOP
