2001 Yamaha 660 Raptor Axle nut issue

Recommended Posts

My 2001 660 raptor seems to be having some issues with the rear axle nut. Seems like about every 2 rides the rear axle nuts back off and loosen up.I average about 75 to 100 miles a ride and this is driving me insane. The rear bearings and seals have been replaced and the axle has been upgraded to an 2003 axle because i had a mishap with a tree,kind of jumped in my way...lol So i got pissed off and ordered a mod quad double locker after market axle nut to hopefully cure this issue. I would love to hear any input you guys and gals my have. Is anyone else ever run into this issue,and how did you fix it? ,Thanks a bunch

Put an aftermarket axle on and you have to tighten the axle nuts about every moto. The only cure for it is an expensive aftermarket locking nut like what you ordered.

Keep in mind that everytime you crank on the axle nut that you are putting force on the axle bearing. That will eventually lead to premature bearing wear.

      having an issue with the unit when running under a load up a hill or in high gear, seems like the belt is slipping, there is a clapping sound coming from the primary clutch like it releases and snaps back in. i don't think I should have a noise like that. this is a friends unit and he has already replaced the primary twice with the same result.
      not sure where to look next

      My friends KQ 300 starts fine and runs, as soon as you put it in gear and try to accelerate its bucks and farts like crazy, not moving... I cleaned carb and it worked good for 1 day... now back to same problem.... could it be such as a bent valve????

      Sorry I suck at these forums so if you see this submitted under update status, my bad. Anyhow this is a new shock for a 96 Yamaha Kodiak 400 4x4 it fits my 96 Yamaha Timberwolf 250 4x4 perfectly. Little narrower are the bottom than the original but everything else is perfect. I extended it to almost a half in from full extension because I’m pushing 350 pounds.  It rides and hold me well. So if any of y'allRace driven shock. have been looking for one and didn’t want to do the research here it is.
