A few days ago I noticed fuel leaking from my carbs. I've read through all of the threads on this website (including most of the info on BikeCliff's website) to try and figure out what the problem is but I'm just having no luck.
Symptoms:
- Fuel flows from middle two carbs when bike is running
- I can't see exactly where the fuel is leaking from but it is NOT from the overflow nozzles
- Bike runs great
- If I take the tank off and run the bike on the gas left in the tube - no leaking
I've pulled the carbs off and inspected the bowl seals, needle, float bowls (needles and bowls do not seem to be sticking and no holes or wear detected). I've been careful to put everything back together correctly. Petcock seems to be working fine (I guess - doesn't flow fuel while 'on' or in 'res' but does on 'prm'). I've checked the float bowl height, 22.4mm.
How often do the fuel transfer tubes (between carbs) go bad? I just can't think of anything else it could be.
If anyone has any ideas I would really appreciate it.
Thanks
P.S. Carbs are Mikuni BS 34SS
