Hi
I run a Suzuki DR/SX 200 over here in England and would like to know if engine parts i.e head and barrel can be grafted onto a DR200 bottom half.

At present i have run the bike with totally standard engine apart from milg gas flow, opened up the airbox, jetted the carb and altered the final drive gearing; oh, and i have shaved 34kg off the weight! That was last season.

This season need to tune the engine further and part of my package will be a Keihin FCR 35mm but before i started porting and boring i would like to know if the LT230 parts will help me, plus i hear that hot cams are available.

Can anyone tell me how wide the crackcase mouth is on the LT230?

Looking forward to your replies.
Regards
