I'm out of ideas right now on this, guys and gals. I noticed my CVT overheating a week ago so started investigating. I'd say it gets to around 175 degrees F. Hot enough to burn you if you keep your finger on it more than a fraction of a second. Normally, it would be barely warm or perhaps even at ambient temp.
For an experiment, I rode it for 50 feet -- took off cover and the clutch bell was the source of great heat. Took off the bell and saw clutch pads are worn significantly but not down to the metal. So I decided to take off the stiff clutch springs I had installed and go back to stock springs thinking the clutch was slipping due to wear of pads. This had no effect. I didn't notice any slipping at any time anyway.
Everything else looks ok such as variator and belt.
I don't want to ride it with it doing this. What does anyone think?
-
The variator is attached to the crankshaft, it's gonna get hot. Not to mention the friction from the belt/rollers/and clutch.
-
Check your cvt vents and variator fan.
-
If your clutch pads are worn way down, they may not be fully locking up in the bell, slipping and causing heat. 50 feet and this much heat! Sounds like time for a new stock clutch, spring, (to push harder), and maybe bell if it has been damaged? :-*

If the fsan fins are OK, if air inlet and outlet are not clogged up,if everything works fine, it is not overheating and forget about it.
In the summer they do get extremely warm.

Anybody that's tuned a cvt knows they get hot. Taking it apart immediately after riding it is very very hot. To hot to touch for more than a second.
