My 1990 used to do that, I just shut off the petcock every time I stopped. I rode it for 1000 miles more and eventually it quit.

take your carb apart, clean everything in petrol, look at the o-rings, maybe replace some gaskets if they need it. It is an easy job that should take less than an hour if the bits are to hand. I would say re-use gaskets and replace o-rings, then see if it leaks after the rebuild.

Once done you will know how to do it, which is invaluable (have had to do it in a bivvy bag in high wind and sand - was very glad I had done it in the shed first)

Agreed with henryuk.

The needle valve might be worn a little, the float pivot pin might be a little tight, the needle riser might be bent, something might be wrong.

Bloody acronyms... took me ages to figure out what a pita was. Over here it's a flat greek bread!

Taking carbs off is a doddle, the hardest/fiddliest bit is normally disconnecting the throttle cable. On most bikes it is easiest to take the whole cable off from the twist grip (remember where the cables route up

Heh, last time I took my carb off, I ended up shredding the intake rubbers on the head-side.

I've heard it's easier to take off the airbox and then take out the carb, but I'm not sure what that entails.
