Hi all picked up a cheap 31k last week started and ran with no issue's Yesterday i removed the exhaust's to fit a set of micron's on it and both pipe's had fuel in them as anyone had this problem now the bike wont start had carb's all to bit's checked and reset float height's today all seem's good in the carb's now the bloody micron's have fuel in them
Carb's not leaking from overflow im thinking the vacum tap is shagged when in prime pos fuel flows well in the on/res there is a slight drip from pipe.
Any help would be great got a feeling the crankcases could be full of fuel
Got a very strong spark maybe wrong on this seem's fuel has been leaking into the engine whilst it has been stood
