?? Added flywheel weight to 2003 EC200, bike ran for test ride now wont start

My other guess is the HV coil wire. This has happened to me twice on two GGs. The bond to the coil breaks down and lets in moisture. Conductor corrodes. HV leaks around insulatiion. When checked you will see a spark, but under compression in the engine the spark may not occur due to the extra resistance in the wire. This problem can occur in an instant.

I have an 03. I will relocate it tonight as well and check the hv wire.

Thank you

What ignition though? Stator harness exit from front @ 10:00 or rear at 2:00 ?

How can I identify the ignition. My harness leaves from the 10 position

Then you have a 2k-2, The Light mx Ignition with the small flywheel, which also explains why you would need the fww

I have been folowing this topic very closely, as I have just made a fww for my friend who have a '02 MC300 with the small fw, we just installed it and tested it last week, but did not try to start the bike since then..

Hope you find the bug, and that it is not related to the fww.

some ignition covers may touch the FWW and therefor may need double gaskets to create some extra play.
not that this could prevent your bike from firing up though...

Also, I have tried roll starting it and the bike fires for a brief couple of seconds but dies quickly like it's choking. The sound it makes for the quick seconds is a very low quite choking sound.

Compression test is complete and it only read 30 PSI. Whats next top end rebuild, and if so where is the best place to get rings. Can the tope end go bad without warning?

That is waaay low, pull the head and have a look. If nothing else prepare yourself to pull the cylinder too.

Yeah its a 2K-2, but had to ask. Occasionally there is someone who wants a weight on a "3".

30 PSI is ridiculously low, so much so that it must not be correct. You would know something is wrong by kicking it, plus, it would not run one minute and not the next.

From that pic of the ignition, it appears to be a mess. Perhaps something is corroded and was disturbed during the FWW install. I still lean toward an ignition problem/weak spark. Go through EVERYTHING.

Here is a pic of a correctly timed 2K-2.

When the cylinder is removed, look for gearbox oil inside the crankcases. It is thicker (and often a different colour) than fuel / 2 stroke oil mix.

If you haven't already removed the top end, do another compression test. I agree 30psi is completely out of whack. I was thinking more of a broken ring and low compression around 75-80 psi that just happend to occur at the time of the FWW removal. The comp. test would just remove one possibility. A ballpark figure is 90 psi needed just to start and run. I lean towards a stator or coil problem. Either find a dealer/shop that can test them or someone w/same ignition and start swapping components one at a time. In the meanwhile, run another compression test, at least to give yourself a reference number when the time for a new piston/rings is needed. Jim
