Well, the flywheel problem is solved.
I had no clue about lapping a flywheel on until Randy told me about it. Even the shop didn't know, since OEM motors and parts don't need it. They just bolted it on as the manual says to do. Since it coughs through the carb at times when it starts, it sheared the key every time it did that.
The shop sheared a couple keys and said they didn't know what to do. Randy suggested lapping the flywheel and I relayed that to the shop. The mechanic at the shop hadn't done this before and didn't clearly understand how to do it properly (keep in mind this is a factory shop, not performance). They sheared another key. They just loose installed the flywheel and put it back together for me to deal with.
I got an e-mail from Doug Nicholas and he said that the flywheel needed to be lapped. I now needed to know wtf was lapping. I called Randy and we chatted about it. Then I looked it up on the web and got a good understanding of how to do it.
Today, I went to NAPPA and picked up some valve lapping compound and brake cleaner. Went to the dealer with my new portable garage. Wheeled my machine into the trailer and inspected the flywheel and crank shaft. Since it had sheared several keys, it had some galling. I took some emery cloth and touched up the flywheel and shaft, then put the valve lapping compound on and rotated the flywheel 12 revolutions one way, then 12 the other. Checked the surfaces for uniformity, and repeated until I couldn't see any high or low spots. Then checked the surfaces with Prussian blue. I had to lap it 5 or 6 times before it had a good fit. I'm sure that the original installation would have been less. I cleaned up the surfaces with brake cleaner and installed the flywheel. I torqued it down, then removed the nut and followed ten's advice and gave it a sharp tap, then re-torqued it. Put it all back together and it fired up.
It did cough a couple times through the carb before it started, but this is normal. The good thing is it didn't shear the key! I shut it off and started it up a couple times.
Thanks to BigD, Randy, Bear, ten, and Josh for all the posts and advice.
It takes a few problems to learn how to do things.
I'm going to Beverly tomorrow to make a few passes. Anybody wanna go? I only have the drag machine, the two scrammys are torn down and waiting for carb parts. So I'll only be making passes at the east end, no trail riding. If 'da boy doesn't go, then I?ll ride his machine for trail riding if someone else wants to go.

Hey Bear and TC............
I need to hook my dad up with you guys for a ride some day. He keeps bugging me about going.
He is a novice rider, but has a good idea. He's riding a Yamaha Kodiak 450.
Would like some easy stuff to start out with.
He has been riding in Montana and somewhere else back that way so far.
He'd fit in with you guys great. Not sure you'd get much riding done, cause he's into guns as much as you guys.
He's ok for weekday afternoon rides, but he doesn't get off work until 12:30 in Lakewood. Doesn't give much time.
Sure he wouldn't mind a weekend either.
He lives in Yelm.
I also found this for you Ute guys if interested.............I think my dad is selling it........[img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-wink.gif[/img]

Good to hear its up Karl.
I have had a z-400 down since June. It ran great but neede a 440. It got that then the clearance was bad. The valves hit teh piston. Fixxed that, then couldn't get it to time, the painted on marks were hard to see. Figured that out, then it wouldn't rev. There was a one dollar part that was missing, and not "missed". It was telling the cdi the tranny was in reverse, so it would rev. That is fixxed and all is good.
EXCEPT, now he says the front tires won't touch the ground. Watch out 450 four stroke class, there is a new dog in down.
