hey whats happening  currently im runnin a 372 x torque   it runs as it should but doesnt seem like it has any snot.
will the big bores on the market bolt right on without problems because of the funny porting thing on oem cylinder or will it b ok

they do not make an aftermarket bb kit for them. I wouldn't recommend one if they did. I get better performance from oem than aftermarket bb kits. if you want for power get a bigger saw or send it in for port work. you can easily gain 40% over stock with porting. it would still    be a every day work saw.
