Just fitted my replacement header pipes all good started her up sounds great cut the engine and noticed fuel dripping out of the carb drains help ??

How long has it been since it ran correctly?

Sounds like the float are stuck...

Not sure what you're calling "carb drains".

Oh and ive just noticed on the picture the little tap above my spanner is what is leaking and the case i refered to is what say makuni on in the pic thanks

Yes, you can take that cover off and get directly to the float assembly. That will also make it easier to diagnose the problem with the leak.

That in the picture is a one way valve for the fluid drain on the airbox. At the back left hand side of the airbox (as you sit on the bike) on the underside should be a drain pipe for the airbox which goes to that valve and the pipe continues down to the rear of the engine.

it is for draining oil or condensation that builds up in the airbox. When the bike is on the sidestand it drains out through the valve. inside the valve is a plastic 'pea'. When the engine is started, the vacuum in the airbox sucks the pea over the inlet hole of the valve and stops the bike running to lean. These valves are normally thrown away so you don't often see them! I know the ones for the FZR250 are no longer available from Yamaha - but they may have a newer part number.

If you don't have an airbox then it wont be connected to anything
