Hi all, at the moment I am riding a 250 Mar in comps. Its a great bike, does everything it should but i think its lacking that something extra in the engine department. Its on its first oversize with new piston and rings, 26 mm Mikuni and thinner head gasket. The engine pulls from nothing, but just seems to lack that sharp response when power is needed. So my first question would be, is this a characteristic of the engine? Secondly I have a 250 gripper engine sat in the corner of my shed and was wondering would I get much benefit fitting this in my Mar chassis, and would it cause me much hassle?
Cheers HIGGO.
