Pull up a chair as I tell a tale of woe. I came to use my bike this Thursday and found there was no power at all. This is related as in my quest to fix this I drained my tank and removed it. After I pinned down and fixed the power issue I replaced the tank. When I came to fill it up however it began leaking fuel out of the overflow pipe. I have no idea why this is, as the carburettor was in perfect working order before and was not even touched during my repair. I know the go to would be the float but how could this have stopped working during an unrelated electrical repair? Dose anyone have any other clues or ideas befoe I tear apart the carburettor? Thanks in advanced.
