I have a 2001 300EX and i want some serious power so i was thinking of buying a 350X motor and putting one of these fst kits in it http://www.fourstroketech.net/atc350xproducts.htm and swapping it out with my 300 motor, anyway, how much could i sell my motor for, if i sold it i would include a basically brand new HMF pipe, thanks, also any body with a 350X conversion can you give me any advice/experiences, etc.
