Bike dies when I put the airbox on

[QUOTE=Garrett;1354940]That was a pic from ebay.

Oh yeah I see that now, giant pic caught my attention didn't notice words lol. I f you are 100% confident in your carb cleaing then it would have to be 1 of a few things as long as your not losing spark when it warms up, which wouldn't be a bad idea to check.
I'd check the fuel filter, the fuel flow out of the tank, Kinked or missing hoses, fuel and vacuum also not sure if those bikes have a fuel pump. How old is the fuel filter, can you easily blow through it? If you open the petcock with the fuel line off does fuel pour out or just trickle

Good luck and keep us posted I'm really interested in finding out what the problem with this bike now

P.s. my offer still stands ill trade straight up for my running and reliable 95 zx6e that I've already put almost 2k miles on this season lol

Fuel comes pouring out when I open the petcock.

Same thing today

What about the fuel filter??

[Garrett]

I figured it out. The oil was contaminated with fuel. It seems the bike would start up and run for 10 minutes til it got overloaded with fuel via the oil. Leaving the airbox off allowed it enough air to keep going. Changed the oil and filter and all it well!

Alright man! That's a new one on me (seen fuel in the oil plenty, but never that it stalled out the bike), did you fix the problem that put the fuel in the crankcase to begin with?

[Garrett]

Yep, bad float needles.

Nice, that's definitely a new one for me too. Now you gotta make sure to put a ton of miles on it so the carbs don't plug up again lol

[stoinkythepig]

Wow, that's really odd. I guess the fuel was evaporating and being drawn in through the crankcase ventilation richening the mixture. Good catch!

Kind of reminds me of a tough boat engine problem, with similar symptoms. The engine would run perfectly with the engine hatch open and for awhile with the hatch closed, but eventually it would lose power and die. Open the hatch and it would run fine. Turned out to be an exhaust leak. The exhaust would build up until it displaced enough air to make the engine run really rich and die. When the hatch was opened, enough fresh air came in to make the engine run perfectly again.
