Bike was running great, but today it started flooding out. With the bike off, fuel will pour out of the intake, more so with the choke on. I assume it is running into the crank case also.

I'm pulling the carb off tonight... Stuck bowl? Needle valve? What should I do about the fuel in the crankcase?


Edit; well, I took the carb off and only things I noted to be odd was a yellow film over everything and that I turned it every which way and no fuel came out... Only when I broke the bowl seal did gas flow out.

 

You don't say what model, but Suzukis are unusual. They mostly have a fuel tap operated by vacuum from the inlet manifold. As soon as you start spinning the engine, the vac opens the tap and fuel flows to carb. So you can fill the carb after cleaning it, or running out of fuel, this tap has a prime position, put on prime for a few seconds and the float bowl fills. Looks like you have left the carb on prime. This wouldn't matter if the float needle hadn't stuck. On all other makes, they have a carb overflow, so if the needle sticks, the fuel just runs out onto the ground, but because of the vac tap preventing overflows, Suzuki don't fit an overflow pipe. So never run a Suzuki on Prime. If the sump oil level has increased and it smells of fuel, drain the oil out and fill with fresh oil. Empty any fuel from the airbox.

 

Sorry, it is an Lt80. I have previously changed the pet **** out for a banshee part and blocked off the vacuum line.

 

Yes, but you didn't turn the tap off before stopping the engine. This is vital if you don't have the automatic tap. Forget oil change as it is a two stroke. I take the plug out and spin the engine on the starter until fuel stops spurting out, find a way of stopping it from sparking before you do this, I've set two on fire from stray sparks when blowing fuel out through plug hole.

 

Clean the carb paying attention to the needle and seat. Run non ethanol fuel or use a non ethanol additive.
Shut the fuel off and let the carb run dry when done riding. When you turn the fuel on, it'll wash the needle off.
