will your minibike roll backwards?? Mine won't; or, at least, not now. I had a long layoff due to a foot injury, and haven't ridden in a long while, so I'm de-gunking my carb now, and when I tried to roll it backwards, the back tire just skidded. I checked the hyd disc brake to see if it was locked up, but it rolls fine forwards. I took the plug out and checked for free piston movement, thinking of a stuck crankshaft or something, and that all looks good... could it be the centrifugal clutch hanging up????
