Yeah 2mm stroker crank JM racing calls it , 1mm up and 1mm down. 1mm is machined out of the head, very little porting the exhaust port is widened, cylinder is decked quite a bit. Because the transfer ports where way too high. It has a violent and sharp hit when coming on the pipe, the 500,s I rode didn,t hit as hard and sharp. It,s very fun and exciting to ride, it runs like a transformer flip the swith and bam 20 + lbs of torque instantly.
