Fuel leaking

Postby Mozeley » Sun Nov 30, 2008 2:21 pm

Hey Guys,

I have a problem with my RT 125.

When I finish riding I park my bike up, and if I don't switch the fuel tap into an off position, then petrol leaks out of the bike.

I've traced where the petrol is coming from and it's coming from a plastic, what I would call "overflow" pipe which is attached to what I think is the Carb (it's a component just before the engine under the saddle) - does this mean that I need to drain or clean the Carb out?

Thanks,

Ben

sounds like the float needle is dirty or a bad float
while your at it clean out the whole fuel system
and do remove fuel petcock from tank and clean its screen

Thanks Dave,

Unfortunately, I'm not skilled enough to clean out the whole fuel system, so I will probably pay a garage to do it. In the meantime, do you think that I will be able to just drain the Carb to get over this initial problem? (looking at your draining Carb instructions it looks pretty easy)

Where are you located? If you're near me, I can loan you my old VM24 carb to see what's going on with yours.

I'm in somerset, UK. So a bit too far away to make the most of your generous offer :)

Well, I've drained the Carb and it ain't happened since.

Dave - you are great at picture instructions and such like. Have you got any picture instructions of how to clean the Carb? Or just instructions will do.

cheers,

ben
