Ok so I have a 2 week old engine on a mountain bike and the bike runs great on flat surfaces but once the surface becomes a little up hill, the bike revs but doesn't move fast, I can hear a grinding, squealing noise from the engine. I don't know if the clutch pads are the problem because the engine is only 2 WEEKS OLD. Should I open it up and degrease the pads.
thanks
