i have a 1998, when i have a lot of fuel in it, and i lean it to a said, (on its stand) it drips pettrol out of a pipe on the carb, i was thinking to float might be stuck or something, why is this happening and how do i sort it out. also another question, there is a little window on the crank case, is this for the gearbox oil level, and how much oil do these take. thanks in advance

my carb use to do it i found out there was dirt in there causing the floats to stick so i cleaned it with carb cleaner and compressed air. as for the sight glass that is just to show there is oil in there. you bike takes 550ml of oil i find pj1 light clutch tunner works best after a long time of finding a good oil.
