Just wondering what to keep.my eyes open for when I open this sucker up.
My clutch doesn't let go like it used to. I stay "in gear" until I'm almost completely stopped. Wrecks my stop and go acceleration. It still engages about where it was, just doesn't disengage neatly.

Could be an issue outside of the clutch. Maybe the contra spring getting weak or torque driver not moving smoothly or an issue with the variator. Anything that would make the CVT "downshift" slower would cause the clutch to disengage later, because the clutch would be spinning faster if the CVT is in a "higher gear". If it acts as it always has on takeoff, it's not likely to be anything like a broken clutch spring or weak clutch springs. If it gets worse or only happens when the engine is hot, after a bit of riding, then it may be springs fading with heat. Could need a spring replacement or maybe ventilation to keep everything cooler.

Finally got into the clutch side today. Cleaned everything, deglazed my clutch pads and the bell, greased what is supposed to be greased, etc...
My spring seems to be a tad big for the spring cup. It was seriously binding in there. I decided to try the ball bearing thing since I had a handful laying around. They're still in there after riding around tonight.
I think the problem is a worn torque driver though. With everything apart and working it in and out it hangs up at the most open position, looks like the ramps are worn. I tried to smooth them with a Dremel a bit but it didn't seem to really help any.
I swapped back to a Swiss cheesed variator cover. I'd put an unmolested in on there as we are in monsoon season.
It is accelerating from a complete stop much more smoothly now but still hangs up when decelerating. Feels unnerving actually as the clutch doesn't release until I'm almost stopped. Makes cornering slow.
I also need to look at my variator weights though. Got to thinking about the fact that I've been running "tuning" weights since May. Them things might be square by now.

Got into the variator, nothing was flat sided. Swapped the 5g weights for 3g weights, for a total of 21g now. Acceleration from a stop is much better with no loss of top end. I'm gonna have to dig through my parts and see if I have another torque driver assembly.

I feel I could do better with a tad more weight. When I get a chance I'm going to try three 8s. Im playing with a tuning set still so I don't have but three of each weight. :/ |
