oh... and i forgot to mention.. im getting a squeaking when i first start the engine until it warms up.
The black dust is normal... How bad are the metal shavings? Minor metal shavings & squeeking can be normal too.
there was no marks on the cover from this. i had some from a previous experience but thats not the cause now. it appears that the dust is coming from behind the large gear from the ways its caked on the casing. ill post pics in a minute.
the silver metal shavings are minimal but what is this black stuff... i hear that squeaking could be a bearing going down....? i mean the motor was running badly.... terribly!
thanks in advance for any help you offer

That dust is from the clutch pads!! (as I said, totally normal)
I would look elsewhere for the engines performance problem.

Is it a silver jet motor?
Beats me, I don't see the motor name you mentioned on PistonBikes but as far as I know they are a reputable dealer.
So you have another broken motor too?
You sure don't seem to have any luck with them.
It could be bad luck, poor craftsmanship, or it could be what you are buying.
That I am afraid is up to you to determine on your own.
As far as trying to make one good motor from two dudes, all you have to loose is your time.

What happened to the flat head screw that holds the small helical gear on?
What was scraping and causing the shavings?
Please upload a few pics of the damage.
Sounds like the casting around the small gear broke which should not affect
anything from working.
