Question about Yamaha Motorcycles
Possibly restricted exhaust or valve worn or piston rings worn take out spark plug hold gently but firmly against the plug hole turn over engine Holding the plug obviously not with spark plug cover on !! It should at least push the spark plug away from the hole with a pop pop pop sound if so hopefully that rules out valves if it's not burning oil then it probably not rings could be timing off or valve seals most engine with leak will run full revs under no load ps also check plug gap :-)

Sounds like you have either got water in the system or poor connections.
You can use something like dielectric grease on each connector. It is a bit of a pain having to open and close each connector on your bike, but once you've done it, you shouldn't need to do it again for a long, long time.

I guess youwillhaveto adjust the clutch cable so as to open the plates more at the pressure plates to let the clutch plate rotate freely instead of binding thus the low rpm.
Hope this helps!
