I have an '07 650 H1. Recently, when trying to take off easy, it acts like the belt is slipping. If I give it the gas, it grabs and takes off. It has 1300 miles on it and it has never had water or mud in the belt housing.

I can think of no real reason why the belt should be worn enough to slip. Could there be some kind of lubrication problem not allowing the sheaves to move properly?

One idea is that if you stop suddenly the ctv does not have a chance to close properly wedging the belt and holding the sheaves open. When you attempt to pull away the belt slips (and chirps) into the lower position allowing you to have the proper gearing.

Secondly belt dust can be a problem even without mud or water in the cvt. take the footboard off and then the clutch cover. The two long bolts go towards the back. Make sure not to tear the metal gasket it is reusable. Then clean everything with brake cleaner if needed. Also check to see if the bolt on the primary is tight (if you never took the primary off then you wouldn't have to worry about this)

Finally I would be suprised if the belt was out of tolerance at those miles and you should be fine with a good cleaning. After you clean things up let us know if it is still happening and what kind of noise it is making ie chirp at start or constant squeel or noting.

Something similar happened to me this winter when I was plowing. I tried to push a large snow pile and glazed the belt by having it slip when attempting to move forward. I changed the belt with an older spare and all was fine. I was also told that you can attempt to remove the glazing with some fine sandpaper by sanding the sides of the belt lightly.

PS I added the make and model to the title

      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.

      Hi folks, a little disparity brought me to this forum.  To set the stage, I'm a 35 auto tech in the industry 37 years now.  Licensed motorcycle tech also, 20+ years.  I race superbike and motocross.  Always done most of my own standard work (outside of specific race machine works) including building my own race bike engines.  Now that skills are out of the way, onwards and upwards. 
      Helping a neighbor with his old quest 500, right front axle seal leak.  Well, looks like everything else - right?  Wrong!  Initially I noticed the CV joint was lacking large lands to place prybars on to pop it out, rather a thin shield like ring very close to the diff seal.  Knowing the ring appeared quite delicate, I only pried gently and the CV popped out.  However this is where things get weird.  Came out only around 7-9mm then hung up again, felt like the clip was catching inside the diff.  So spun and pulled, spun and pulled until I was blue in the face but no success getting it out.  Also while it was out, I could see that the delicate ring around the outer circumference of the joint was actually the sealing surface where the seal contacts, instead of the norm where the seal rubs inside the diff much deeper and stays cleaner.  I've never seen a joint like this, also the service manuals photos which apply to 650 also reflected a standard joint I am accustomed to rather than this one I was fighting with.  Rather than break something in the diff, I decided to stop while I was ahead and reassemble the machine before something broke.  (The joint would pop in and out of place easy enough, just wouldn't slide out further than 7-9mm).  While the joint was a little out and sealing surface exposed, I cleaned the seal and sealing surfaces clean as possible before putting back together.  Seems to be holding for now, but eventually I'm sure the leak will come back.  Any thoughts as to why that CV joint just refused to come all the way out?
