Problem.

Could have water or dirt in the tank. Drain it and try again. Does your bike have a fuel filter?

Maybe...I dont know. I'd say probably.

If it does change it. If after all that and it still doesn't run, I'd start looking at the magneto. At that point you've eliminated gas and air problems, so the only thing left is spark.

The wire for the rear cylinder looked somewhat like it had some corrosion on the end that plugs into the coil. So I may replace those anyway.

Fresh fuel would be my first thought. Water will float to the top and you get gas until the level drops...

Possibly something in the tank or lines may have filtered (filter?) thru to the carbs and gotten a needle or float stuck.

When one sits that long anything may be the cause...

I had winterized a yamaha once and had trouble firing it and getting it to run. Turns out mice had collected my dogs food and built a nest in the exhaust. When I finally got it to breathe and fire i held the throttle wide open and shot dog food out shotgun style!

I cover the exhaust when I put it away. There's definately nothing in it.

I just thought...The gas is in the frame...Does it have a vent hose that could be plugged or blocked????

Uhh, no. Fuel floats on water.

Think, Exxon Valdese.

You know,I've always heard that water floats on gas too...but Chem 101

Specific Gravity
Introduction

Specific gravity is a way of relating the density of an object to the density of water to determine whether or not the object will float.

If an object's specific gravity is less than one, then the object will float. If the object has a specific gravity of greater than one, it sinks. So dense objects sink in water and less dense objects float.

Importance of Specific Gravity

Specific gravity is a very important concept in the water/wastewater field. The specific gravity of a substance will determine where a compound can be found in water in case of a spill.

Let's consider gasoline. The density of gasoline is 0.6 g/mL and the density of water is 1.0 g/mL. So the specific gravity of gasoline is:0.6

Since its specific gravity is 0.6 (less than 1), gasoline floats in water. So when a ship leaks gasoline into the water, the gasoline stays at the top of the water.

In contrast, the specific gravity of palmalive is 1.1, so it sinks in water.

Can you "expose" the injector assembly to see if it is getting fuel in the throttle body? Also,check the fuses and make sure you didn't lose one. I have to disagree with Rider,in that modern bikes also need computers/electronics to run,just like cars. Did you wash it after your last ride? Do you have a Power Commander or other Fi device? Could your electronics have gotten wet? Is it possible that you inadvertently pulled a vacuum line while you were messing with it last week? Does it have a choke and is it stuck?
