Sorry guys, I been busy and just saw your questions.
Tracy- if by 'plate' you mean the half pully thingy then yes, it slides freely. There are three metal balls between that and the back of the clutch housing, they also move freely. Sorry I don't know more about these variators, just let me know how I can answer that better. As for the short intake, it came fitted onto a spare Motobecane cylinder that came with the moped and is obvioulsy made to fit perfectly. That's all I know about that. I can measure the diameter of the tube if needed.
Prancer - $30 including shipping, shoot me an email if you want them.
Eric - Yes, I sent you an email.
Steve - by 'header' you mean the exhaust header? If so, the threads are a little rusty but good, I can clean them up for you, $20 shipped. Send me an email if you are interested.
