The idea was to create something more reliable and less expensive than the Daytona/zongshen 212cc 4 valve. This motor cost me $560 and i know the ZS212cc 4v is around $1100.

I will be happy if it can hit 90mph with the 17/31 sprocket setup.

Can you post a few close up photos of the mounting of this 4 valve 250 in the Grom clone?

I still can't believe it. I mean photos showing the head in that frame!

Thanks!
