I have a K1 crank that is undersized by .002-.003 on the area where the crank sprocket fits. I tried an old DC gear, a cloyes gear and a Rollmaster and none are even close to a light press fit. I should have caught this when I bought the crank but too late now since K1 isn't even owned by Carillo anymore. Any easy fixes for this?... like a gear for another brand of engine that can be honed to fit
