It might have something to do with that big anchor on the back end.

Simple things: Check your chain slack in both chains. Also check the position of the shifter knuckle on your clutch pedal.
Complicated things: Have your clutch and tranny checked. It may be prematurely worn from the extra work of turning the big wheel.

I am in no way a qualified mechanic but it sounds like it may be transmission trouble. Sorry.
