Hi guys, I have just purchased an 05 250SM with only 1,000 miles on the engine. What advice is there regarding tuning and parts for more power so that I can use on track days? I understand that the 300cc cylinder and piston fit, but which model and can the cylinder be tuned for top end? What later model plastics fit for a newer look? Who has owned one before whom has any advice, tips or stories?

Thanks all,

Duffs
