Not new to the forum scene, amazed this one is still as busy as it is though! (seems to be IanDohaan keeping it alive) I work on carbuerated and EFI Japanese cars so I'm not completely helpless, but I'm a mite bit stuck.
Three days ago, I encountered my first mechanical issue on my 3-week-old purchase, a maintained 1994 Honda CBR900rr. I have read through a collective 30 threads that have any keywords related to an overflow problem and am convinced it's time to make a post.
The bike ran quite literally perfect for the three weeks I had it. Rode it home from work and then set it on the kickstand after shutoff. Fuel started dripping out a hose of the left side. It only stopped with the petcock being switched off.
I then started it to move it to a buddy's house. It ran for a minute until it just chugged slower and slower, then died out. It eventually stopped turning over.
I hit r/Fixxit on Reddit after reading up here, just to avoid annoying y'all with what looked to be a stuck float needle. You can read that small thread here.
The bike sat with float drains open for a day. I tore out the carbs, cracked the floats open, and the interior/needles were pristine. Ran Gumout carb cleaner through the entire system, but I did NOT open the vacuum diaphragms. Reinstalled, got the same leakage. It then stopped turning over, as if it's flooded.
I read that it's possible a cylinder (or several) aren't getting spark, which would cause excess fuel to enter the cylinder and then stop it from turning over; however, that does not explain the leakage, does it?
I've attached all related pictures.
Edit: My FSM is coming on Wednesday, woohoo! Been using the '96-'98 PDF version so far.
