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.

Hi,
This weekend went on a trip with my all brand new cforce 1000 touring, went from tarmac to reach the small muddy places and dirt and even sand.
Was running great until tre situations occurred:
First, after putting 50km without problems and still respecting the break in on the engine, we came across a sand small uphill and just turned the 4x4, and almost reaching the top, got a strange loss of traction with a noise like something was slipping, the noise looked to came from the front but cannot give 100% sure it was the differential or not, but something was definitely slipping, also i disconnected the 4x4 and tried to make the uphill only rear traction and almost reaching the top the same noise. I got a friend that was on my old 850XC and it drove pass this small uphill almost at idle.....what do you think??? Belt Slipping, Front differential or Gearbox/CVT?
Second, after this situation, i had the engine light going from on to off on the trail back home, but on the trail back home, i had no issues with temp rising nor noises nor anything, we drove normally, but without sand nor uphills, just rolling normally on dirt roads.
Third, a strange situation, riding on normal mode, i was going at 38 to 40km rolling but the engine was revving on 4000rpm at those speeds, i feel that it was a little bit more reavs than usual for that speed, but this is my perception, what do you think on this???

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?
