Might want to start with a secondary spring if you have not changed it since last year, they tend to get weak and will not backshift.

You would lose ALOT more rpm than that is either of these sensors kicked in on you. Start with what was suggested and try a new secondary spring. I assume this is a sled that you owned and rode last year and it did not do this then? If the sled is new to you, it may not be clutched quit right either.

depends on how olod the belt is as you climb it will get hot and sqishy causeing the engine to pull harder lossing rpm so try a new belt

200 RPM that should not be the sencer, like said above you would lose why more than that. Sounds more like a spring in one or the other clutchs, maybe even something as simple as your clutches being out of line. Or even a bad belt.
