Thanks for the reply ernie. I'll definitely check all these.

One thought I have though it don't these bikes have 2 ignition coils? These have 2 CDIs, 4 Spark Plugs+ wires, so I think 2 ignition coils.

Thats the only thing that makes me wonder. Because if I take one spark plug off each cylinder, it will still run fine! Its weird, but I think this design is for better reliability and spark or something.

But I'll definitely check this out.

The carbs have recently been cleaned, the batteries good, the air filter is good, and the wires seem okay.

The only real weird thing is that it has to be both cylinders. These bikes have 2 carburetors. The bike WILL start on one cylinder. Therefor if flooding is the issue, both cylinders must be flooding. I was thinking a leaking float valve or stuck open float, but the chances of both doing it at the same time is extremely low.

Any thoughts?
