many thanks for the advice, i am making progress because i have started the vehicle and no fuel is leaking,
now that i have got is started im hearing a loud noise from the top end of the engine only when the revs slow down or when i ease off the throttle.
if i leave the bike running on the choke, the rev slow down making that noise then cuts out.
thanks for all your help kirsty and caine

U leave fuel in the carbs for a long time(2years)and all the good stuff evaporates leaving behind a kind of jelly.this jelly clogs float valves/main and pilot jets and just about anything it can when u add new fuel.uneed to strip and clean the carbs.The pipe u refer to is the float overflow pipe,there is one for each carb and is connected to nothing.its job is to drain execess fuel away.Buy a haynes manual if u'r doing it yourself,if not then get garage to do it,maybe cost a couple off hours.Next time u store it,switch of fuel at the tank and then start and run till it cuts out.thatway there is no fuel in the float bowl's,no problem.

ooo ok understood, but how can i confirm which carb is at fault

hi kirsty, thanks for the responce, just wondering if i should open up the accelerator using the throttle, then shud i use the screw driver to push down into the carbs, better yet do you now of any diagrams or pics, and is there suppose to be anything at the end of the drip pipes cos i was looking for another pipe that may have come off it
thanks again

sounds like a sticking float in 1 of the caburettors float bowl, try tapping the carb float bowls with the handle of a screwdriver, if no luck then the floats and heights will need to be checked. stripdown carb job.
