No torque when acclerating

I have a 2004 rhino with cdi, a larger jet, and 27 inch tires. When accelerating it feels like its starting in third gear and after a few seconds it "downshifts" and has power again, however if starting on an up hill it will continue to bog down because it has not reached whatever speed it wants to "downshift" at (yes i do realize the rhino has a CVT transmission and does not have "gears"). Originally i thought that the v belt was slipping, but upon inspection i found that the belt was in good shaped, the sheaves were clean and smooth and it was within spec. I replaced the belt anyway and still have the same problem. Any thoughts?

you need to put a clutch kit in it.

start with a stiffer secondary spring, this will keep it in a "lower" gear longer.

Thumbs up no power or torque

Like one coment said you have too look closely at your wet clutch if you did check other stuff.First of all,is the oil getting dirty fast 'black;,and have a bad smell.Also did you take appart the primary clutch before changing your belt they are not easy to mix up like the sliding wheights,it happened to me last time I took it appart to clean! Anyway I hope this helped you!

Clutch issue?

Mine is having the same problem. Was told to clean, re grease and inspect the weights. So I replaced the weights and regrease and replaced the belt. Everything else looked good. It did not fix the problem. I noticed that this has been getting worse over the last year but really screwed it up last weekend riding.Stuck in high in a bad spot and had no choice but to creep up hill in high. Knew it would screw it up. Something is wrong. Runs good after the intial takeoff. If it had gears seems like its taking off in 3rd gear. Could this be the main clutch in the powerterrain in front of primary clutch.

remove the cvt cover...start the engine in neutral....rev the engine up and back to idle and watch the belt move up and down in the pulleys to make sure the belt is traveling all the way up and down in the pulleys... if its not there is something wrong in the sheave or the secondary pulley........

I opened it up this morning and did just what you said and it seems to work ok. Not sure at what rpm it should start to open up up but it does. Could there be a problem with the secondary spring? When put it in drive and start to accelerate it moves slow but the more you accerate you don't really feel it engage until you get it moving just like starting in a high gear. Or like a car with a badly worn clutch. Could it be the main clutch behind the primary sheave in the driveterrain?

This all happened driving in high when it should be in low. Seems like a burnt clutch

Yes the rpm went up. Is the wet clutch the part on the in side? Everything looked good and sounded good when I did your test. I wondering if the spring is bad?
