I did several searches but can't find a similar issue
I recently restored a very low mileage (4K miles) 95 CBR 900 that was garage neglected for 15+/- years
The carb was completely packed with varnish. I overhauled the carbs and replaced all o-rings and jets. Reassembled bike and have an intermittent gas leak out of the "far left" carb. Sorry I don't remember the carb numbers and my 5 y/o has replocated my shop manual for me
When I open the petcock and start the bike it may OR usually won't leak and it idles and runs beautifully up to 55 mph. When I return and park the bike it usually will start leaking fuel when turned off OR a while into idling..
The fuel appears to be dripping off the bottom of the carb onto the starter area. When I turn the petcock to off after a few moments the leak will stop. Initially I thought the float needle was stuck open and causing an overflow - BUT I think I've learned that this condition would drain fuel out an overflow hose? Or does the overflow from a stuck float/needle cause leaking at the bowl cover itself?
Could this be as simple as a bad seal in the bowl cover itself? when the fuel in the bowl gets to a certain level it's leaking past the seal? I rebuilt the carb a second time and the float and needle appear to be working fine. The bowl seal is new and appears to be seated in the grove properly.
One other thing happened of note. Yesterday with the bike off, no leaking, petcock set to "off" and on a track stand. When I transitioned to the kick stand the carb started dripping immediately. Is it possible the fuel in the supply line shifted to the carb in question when it was leaning on the stand?
The restored bike is running and working like a charm with the exception of this fuel leak. Thanks in advance for any advise as I'm getting ready to pull the carbs again - I just don't know what to troubleshoot while it's apart and am DYING to go for a long ride sans any fuel leaking onto the engine.
