2015 pro s 800
Sled seems slightly under powered, won’t rev past 6900rpm, and tops out at 85mph.Any help on what to check next would be greatly appreciated. Here is a list of things I have done and verified good.
-power valves cleaned, cable is not broken, electric motor does sweep/ move when sled is first started. Does anyone have instructions onto how to properly adjust the cable, I was thinking they may not be opening all the way?
- reeds look good
-125psi compression on both cylinders -both coils produce strong spark
- check engine light is not on
- on Non-ethanol mode & running good fuel

It doesn’t seem like a clutching issue, but I’m honestly no expert on that stuff.

This all started after replacing the motor. Almost feels like a limp mode.

Thanks in advance.
 
You checked everything I can think of. Clutch wear could be an issue. If I remember correctly the EGT on the early 800 AXYS motors had a tendency to fail. As far as the cable is concerned it’s POO digital wrench procedure.
