so this may be where some roots of the warrior engine came from. The sr 250 had a very similar cylinder and head to the warrior just smaller and I guess people would use warrior pistons as replacement since there's no aftermarket. This guy bored his t 84 mm for a wiseco warrior piston and did the head work to fit the warrior valves
