Got a 2011 425 EFI. It eat 2 belts, so I replaced the drive clutch assy, rollers, spacer and movable face. Put on a new belt and after 30 min of riding, it eat another belt. any clue what can be causing this?

Well I don't have any experience with them but I've read that if the distance between the engine and the gearbox isn't correct the belt can flap and hit the case and self destruct.. It will all be messy now but you might be able to see a polished or rubbed bit inside the case to indicate it had been hitting for a while..

Sounds like you did the clutch update. I did that with my 2012 model because the movable face inner was worn and it wiggled on the shaft causing the belt to get real hot and slip.

Even with the worn parts, belt didn't burn up. Are you using the correct belt and did you install it correctly? They have arrows on them because they are directional.

If they are getting torn to pieces then I'd suspect they are hitting/touching the case..  probably only at certain revs when the belt flexes and flaps.. 

I'd leave the cover off and either sit there revving it watching for excessive belt flapping, or go for a ride and see if the belt survives without the cover on.

      Hi, I have been around everything with a motor since I was little, and finally purchased more to get my husband, and kids involved. I have 4 quads I will be searching around for information on. I have two 2002 Suzuki LT80K quads, a 1997 Yamaha Timberwolf 250, and a 1996 Kawasaki Bayou 220. I have had different ones throughout the years, and plan on buying another Yamaha Banshee. I plan on trying to learn more about all of them, so I can customize some of them. I know nothing about them besides how to race them, my dad always took care of the rest, but figured it was time for me to learn.

      2008 Brute Force 650, clutch is slow to engage
      By Coyote251
      I'm trying to help a buddy out with his bike (he's not really on the internet or familiar with these forums) and I'll admit that I am not super familiar with the transmission and clutches in these bikes. I owned a Brute a few years ago, but never had an issue like this that I had to troubleshoot.
      So basically my buddy bought a group lot of 650's to build one good bike out of. He got it all put together and has it running but when he pushes on the throttle the clutch doesn't engage till the RPM's are quite high and even when its moving it doesn't really speed up, almost seems like its in "limp mode". He's tried 2 different transmissions so I don't think that's the problem. 
      Is there any adjustment on the clutch engagement? Anything else I can tell him to look at? Let me know if you need anymore information if you think you can help.

      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.
