Running on one cylinder.

My 6T is only running on cylinder #2. Cylinder #1 has spark and cool air coming out the exhaust. Does this sound like a valve problem?

Anyone? I want to ride it and not just look at it.

If cyl 1 has compression,just replace the spark plug.
If it doesn't have compression,check the valve clearances and make sure the valves are moving up and down and not sticking when you turn the engine.
If the valves seem OK and there's still no compresssion,take off the head and look for a hole in the piston.

I'm perplexed because the spark is great, I watched the valves move while the engine was running and it has enough compression to blow my finger off the spark plug hole.

The bike sounds like it's misfiring, so could this be a timing issue?

I'd change the spark plug........simple fix if it's the problem. You could also check for a holed piston with a small flashlight shined down the plug hole; but it sure sounds like an electrical problem. Also, when the engine's running, it still might generate enough compression to move your finger off the hole, but not enough to fire the cylinder properly.
Just the $.02 worth from the "village idiot": Jim

I have swapped the plugs twice.

What plugs are the best replacement for the discontinued Champion L10? It currently has Champion L82C plugs.

Are you using points or EI? Getting a good spark doesn't mean much if it sparks at the wrong time.
