vm 29 semi flatside question

[nickodemon]

Being naughty as this has nothing to do with my fazer thou, but my gsxr 750 'slabside' I have recently replaced the starter, ultrasonically cleaned the carbs, replaced the float needle valves and the bike still leaks fuel if fuel tap left on. Next issue is if i leave fuel tap on it lets fuel into the combustion chamber if left overnight, which causes a hydraulic lock - this was the reason i got a new starter, as i thought it was knackered. funnily enough it was pretty goosed, as the fuel leak ran onto the starter and removed the internal grease . Anyway does anyone know why it is letting fuel into combustion chamber? I know if i turn the fuel tap off i will have both issues sorted, but i owned this bike 8 years ago and never needed to turn tap off..


Ps... Fazer has been rebuilt after accident and has been in use for last few months
