Took the tank off (2005) today and had to fully drain it as the pet**** was passing when in off position. Found the pet**** washer, 3 hole, to be slightly perished hence it passing. Need a new one, any ideas on locating a new one etc?
The basic answer to that question is NO. The needle valve in the float chamber must be dodgy. It is a hazard and a danger for the carburettor to leak petrol. - full stop - even when on the side stand. Notwithstanding the danger of ignition and conflagration it's wasteful! Martyn
Having said that, its not uncommon. The float can stick when the bike is on its side but seems more likely that the float needs adjusting. As Martyn suggests, I would check the needle valve before anything else though.
