    hello from william atwww.moto-scoot.net
    we are a product developer for a large u.s. motorcycle and scooter importer, and we have a new motorcycle coming in to the usa this year with a zongshen 200 engine. we need performance parts for this engine, does anybody make a hotter cam in a big valve head for this, and will the 250 zong top-end bolt up? i believe i have seen a 12 loop stator, and a better clutch for this motor, but google searchs are pretty slim on the info out there. if parts were to be developed & produced for this motor, do you think there is a large market for the performance parts? the bike is the skyteam ace i have in the attachment, but the usa ace will have this zong 200 cg motor-b that i am asking about, and not the 125 in the picture. cheerz!
