Hey all, first post here though I've been reading quite a lot on the forums and gaining some good knowledge. I think I've seen the symptoms from my bike on other posts, but I just want to post the details and see if I'm on the right track.
The bike in question is a 1997 Katana 750 with about 3k miles.
I put the bike up last fall after noticing a fuel leak. Didn't have the time or $ to deal with it then. I assumed it was maybe a cracked line or something similar. Anyway... I pulled the tank and the lines and everything looked fine. Reading some posts lead me to believe it may be something with the carbs.
This past weekend I installed a full V&H exhaust (the SuperSport, not the SS2R). I also installed a pair of K&N oval air filters and rejetted with Dynojet Stage 3 needles and jets (after reading another post on this page I may go to stage 1 or what the poster called 'stage 2'). I also replaced the float bowl gaskets and o-rings on the floats. I didn't touch the pilot needles/jets or mixture screw/spring/ring.
Per the jet kit, I set the mixture at 2.5 turns out and fired it up. It started running after a few tries, though I did notice a plastic burning/acidic smell which I assumed was probably paint or other burn-off from the new pipes. There was also some dark smoke which made me think the bike might have been running too rich.
Before the bike settled into a good idle, there was a dump of gas mixed with maybe a little oil from the crankcase breather hose. I shut the bike down, cleaned it up, turned the mixture screws back a full turn (so now at 1.5 turns), and tried again. The bike ran again for a few minutes, and then dumped the gas/oil again through the crankcase breather hose.
Is this a stuck float problem? How can I tell if the float is stuck? What should I be looking for? Is it a piston ring problem? The engine oil level was fine and the bike sits in my garage during the off season.
Sorry for the long post but I wanted to get as much detail out as possible. Any insight is GREATLY appreciated!
