Ok, lets back up a bit ...

"I have rebuilt the carb twice and it is recieving fuel properly. When i pull the plug after kicking it 10 to 15 times it is wet without an buildup, for some reason it just wont fire. On the 10th to 15th kick the bike does a nice big puff of smoke si i believe that combined with how it feels, tells me i have good compression."


You also stated that you have replaced the plug, Is this the plug you replaced or is this the replacement? Is it wet from fuel? Oil? Coolant?

1st step is to go back to what was changed [most likely the culprit], how much clearance is there between the FWW and the components on the stator? Check the components for abrasions due to contact. Take a good look at the windings, wires, igniter.

Have you tried putting the old FWW back on and trying to start it?

FWIW, the spark plug keeps nagging at my brain on this. Your description and evidence just sound so simple, like a fuel fouled plug. When you are checking the spark, do you hear a nice rapid "snap" when it sparks or is it a slow quiet spark?

I would think that if it were an issue caused by the flywheel, there would have been some kind of running issue [ie;popping/sputtering/hesitation] during the checkout ride. You said that it ran fine and you simply shut it down and parked it for 4/5 days.

heck, it could be as simple as a critter having bitten/pulled the plug wire and when you pull it over to test for spark all is good until you put it back into position, opening the connection again, thus losing spark when attempting to start it.

It may turn out to be something else, but I have found most often when i get stumped on an issue [30yrs as a tech, I have been stumped a few times] it is from "over thinking" the problem and going back to the basics will quickly get me in the right direction.

Someone already mentioned to do an actual compression test, that would be the next step for me.

As the over thinking continues in my head... have you checked your coolant level? Is it low, due to a possibly bad cyl head o-ring allowing the coolant to seep into the cylinder after it was shut down. That would cause starting issues. Sometimes a latex glove [like a Dr uses] stretched over the radiator fill can show this. If it is bad enough, you will see it inflate as you continue to kick the motor over for a bit.

JMO's I hope they help.

One more thing, have you tried to roll/bump start it?
