I need to add one more thing. After you get the scooter back together and if it still does the same thing, you can remove the CDI and put it in the freezer for about 1/2 hour and then plug it back in and see if you get spark. This will let you know if the CDI unit is shorting under heat. I would also test the output of the stator while its warm to see if it is working and then test it once it cools down to see if it produces any voltage. Brent told you in a earlier post what the out put should be.

Ok not sure if it was me removing the locking bolt or just some of the adjustments i made, but..
Problem 2 solved.
Fork no longer locks up at speed.
Problem 3... Still an issue... big issue Got the bike running today for the first time in 2 days. took it to work around 7pm when i was leaving around 10pm it started for about 30 secs good idle no problems, it was on the stand.
I hopped on it and kicked it off the stand... died... would not start again. almost like it was flooded... i was parked at an incline if that makes any sort difference.... this is really pissing me off people!

This could be a difficult on to solve because you have two things that may be affecting it. The first thing could be electrical because some of the scooters have safety switches on the stands or when you pushed off the stand you could have a wire that broke connection. The second thing could be fuel supply as the float level may not be correct or when you pushed it off the stand it jarred the float enough that it stuck open or closed.
My only suggestion would be to check and see if it has spark while it is on the stand and then try with the stand up. You can also check out the float/ needle and seat to see if there is a problem there.

I would suggest checking the plug right after it dies to see if your suspicion of flooding is correct. If it's flooding the plug will be wet and likely very dark. If the plug is dry after it dies, it's not flooding.

So are we veering away from the idea that this could be the stator? Il be picking the bike up at noon. Fingers crossed that it starts!

Brent, that was a good reply... As they say K.I.S.S. (Keep it simple stupid) I tend to forget that and go too far in depth when it could be a easy thing. You are correct, checking the plug should be the first thing to determine if it is flooding or not. :clap:

It could still be an ignition issue I suppose, but it just makes more sense to check the easy stuff first like marshin said. You can check the plug and see if it's flooded in less than a minute if you have tools handy. Figuring out if and why an intermittent spark issue may exist is not so fast. Just to cover the bases, if the plug's not showing signs of flooding then check for spark real quick before you reinstall the plug. Both those checks will take a minute or so. Plug wet, we need to figure out why it's flooding. No spark, we need to figure out why the ign is cutting out.

Thanks for the help so far. Tried to start it at lunch... Went for a few secs and died.
So I walked it a mile home... Checked the plug. Very wet outer edges looked like they were never used.. Noticed fluid leaking from my exhaust port.... So thats one problem. Took off air box and noticed the carb breather valve was pinched off... Could that gaber been causing the flooding?

Pinch your nose shut with your fingers and try breathing in through your nose. See how much air you get, this is the same thing happening to your engine, its not getting any air and cant breath.

Ok Updates:
Problem 3 -- cured... sort of... Problem 2 - is back... crap!
Problem 3:OK Ive got the bike to consistently start and run now, but the carb is doing some really wierd stuff. Idle screw needs to be screwed in all the way or very near all the way to get a good idle. Air\fuel screw is also lacking effectiveness. LOTS of smoke. think I almost killed myself in my garage trying to tune it tonight.
Problem 2: Pretty sure it was gone the other night, but either way its back now. took the shell off the front and did everything i could think of to move any of the cables out of the way that may be binding up ... cant imagine that it would be the problem, but its not the bearings and im out of ideas. guess ill find out if it worked tomorrow morning. a co-worker who used to work at a motorcycle shop said it could be something crazy like a bad ground... so the power then goes through the frame and uses the fork as a arc and welds to it... interesting story but, considering that i can move my fork freely when its at slow speeds... im thinking thats not the problem.
Almost there!

Need to get this fork thing figured out. Bike tried to kill me this morning.... Going to beat on the fork this weekend if I can't get it after that I'm going to a mechanic... Bah! One thing I've noticed is that my first time wot after starting the bike it gets some awesome rpms... Almost picks up....then after I come to a complete stop. It iwill not get back there without a long stretch to get back to those speeds

Almost sounds like you have a leak in the base gasket and it is sucking in air. This would account for your fuel mixture screw not working correctly and you high RPM's and then dying.
