650/X-2 Grrrrrrr pulling my hair out

Hello newbie here, a few months ago I bought a x2 650 1989. My first attempt at starting proved fruitless with plenty spark and fuel,ran battery flat trying so charged battery tried a few hours later after a while she fired. I quickly shut her down and went out on the river she ran sweet and did a hour. She then sat a month or 2 but fired right up,I did about 2 hours before she died on me . So ended up finding no spark ,so replaced cdi and rectifier only to discover it's the exciter coil. So managed to source a new coil and fitted it and sweet plenty of spark again.put back together and still no go? Plenty of spark and plenty of fuel? But won't bite at all? Thinking if has fuel and spark and no fire maybe trimming? Can't check it with light she won't run. Removed flywheel again and double checked trimming . all my marks line up to where they were,charge coil on top and exciter coil bottom( sound right?) so what else would stop it firing?i really need help my dad comes up on holiday( only once a year) and has always wanted a go of a jetter, I have a week to sort it.any advice very much appreciated.

Did you install the woodruff key properly when you installed the flywheel?

Compression, Fuel and Spark means it should run, if the spark is happening at the correct time.

Have you tried priming the cylinders with fuel through the spark plug holes, then trying to fire it?

thanks for the fast reply yeh woodruff key is located in its key way ,and have tried fuel in pots even though she has plenty of fuel anyway just tried fuel down the carbie lol desperate . Can only possibly be timming? The new exciter coil was a new coil and looks and fits the same however I noted the exciter wire is black( old one is red) and wire comes from bottom( old one wire comes from top) don't know if this would make difference? Also onl coil is a bit worn and damaged. I re lined the baking timming plate with the three marks I made plus the screw washer marks. Thinking of pulling it apart a forth time and adjust timming one way and try the the same the other way? Your thoughts

It wouldn't have any fuse if it's stock 650 electronics. I had this issue with my x2 a while ago... I was getting spark and everything but it purely just wouldn't start, spark wasn't that strong though. So I started change electronic pieces around but it ended up being my stator (I had extras of all the electronic components so it was convenient to test out different pieces). But I would look into that wire, typically all black wires in a ebox are grounds but if it was hooked up wrong my guess would be no spark at all due to a short in the ebox so I don't know what to tell you exactly. A list of things I would check...

- Make sure to try starting it with no priming (could possibly be flooding it)
- Check over ebox wires and make sure they are correct (Manual diagram is useful)
- If you can get a hold of a extra CDI and stator... swap those around one at a time to ensure parts are good in the ski (never hurts having extra electronic parts around anyways when owning a older kawi)
- Check plug boots have a good connection with coil wires
- Clean and check magnets in the fly wheel
- Check the ground cable to the engine, and maybe just for test purposes, add a extra one strait from the battery terminal to the base of the spark plug when trying to get it to start maybe the spark plugs aren't grounding properly when they are in the plug holes.

Hope this helps give you some idea.
 
Dont even have to pull the flywheel cover to test theses.
