How much of a difference do t rex cylinder make over stockers.... My buddy has a 4mm stock jug all built by tyson that make 108hp and just got some t rex cylinders and wants to tear down his good running bike and swap out to these cylinders.... He doesnt know what type of porting they have supposedly the have a triple exhaust port?? That is what the guy told him anyways. They are brand new first bore and all. I told him he should take the cylinders up to tyson and at least let him look at them before he tears apart his good running bike. He doesnt really know alot about this stuff he bought the bike as is. So ?? is do these cylinders make quite a diff?? Im sure if there setup right they would? Just a hondo guy here dont know much about the shee stuff.
