Hi all, can anyone shed any light on why my MC16 is letting fuel through to the crankcase , the bike is not running when it does this and the fuel tap is working ok and turned off, its just the residual fuel left in the carb that is pissing out underneath the left side engine cover.

Any suggestions gratefully received.

Regards
Brian

Are you sure it's not the float needle stuck, causing it to come out the carb overflow pipes, running down the sides of the motor looking like it's coming out the cases.

Thanks for advice, found the problem - leaking fuel pipe, just need to get the bike to rev cleanly now , not sure if its carbs or powervalves, any advice would be greatly appreciated.

The valves do seem to be erratic ?

Cheers
Brian
