Steep hills my bike has no power once you have stopped or are lugging, sometimes when slipping the clutch revs go up and straight to a bog even at WOT.

It just bounces between slipping revs to bog with no power no missfiring, just 0 power at all. Quite frustrating.

In the mean time I will up the rear sproket to mask the problem until I can get a fix.

Bike is a 2011 ec250.

I just fixed the power valve tension issue/hitting case, that helped with low end power a lot, how-ever it made the bike's warmup a lot slower. Bike will miss during middle of the rev range until really warm (at least 5-6 minutes).

Please help.
