Gas coming out the header flange?

[h8r]

I've been having problems with my bike for a few months now. Just before winter it started starving after a few minutes, then if I let it sit for a bit it would start up okay and I could keep riding. I decided it was a good time for a fuel system overhaul, so I drained the tank, replaced all the hoses, clean the carbs, get a new choke cable, and make sure everything was good. After all of that, the bike wouldn't start. I checked spark, it looked good. I checked fuel, it was going into the engine, I could smell it on the plugs and out the exhaust. I decided to leave the bike sitting over the winter and fix it when I had time.

Now I've got the time, I rebuilt the carbs last night and put them back on the bike. I hooked it all back up, turned on the choke, and started the engine. It started up a little slow, but okay. Only, it started dripping fuel out of the header flange on one of the cylinders, and apparently there's a lot more making it's way into the exhaust, since the muffler joint was dripping also, and there's whitish smoke coming out of the exhaust.

I don't even know where to start, anyone have any ideas?

Hydrolock ... fuel fills up the chamber and as the piston and valves move around, it squirts the fuel everywhere, and sometimes bends a connecting rod.
You're floats are prolly overflowing and you prolly ahve gas in your airbox as well, unless you have the bike parked facing down hill ... then its in the chamber ...
Cool.

Are you sure you don't have a Gas Line coming from the Petcock to the Vaccum port on the Carb?

yeah do the float height check from the main site and are you leaving it parked in PRI?

Looks like it was just gassy water that had found it's way in through a crack in one of the carb caps. After letting it run another minute or two it dried up and stopped smoking. I repaired the crack with JB weld when I rebuilt the carbs and it looks like that sealed it up well, but I'm still having trouble. The bike starts and idles around 1500rpm, but it's not smooth, it stumbles and surges some. If I touch the throttle it dies right away. If I leave it idling for a while, it'll usually surge up to 6000rpm and stay there. When it does this it seems to run great, only I'm not touching the throttle. It seems that I have bigger problems than dirty jets.

Possible Air Leak.

Time to tighten up the header flanges/collars.
