Where is this penner you speak of need info on how to raise the max rpm and open secondaries 100. Mike bike is built and hp and trq curve is still climbing Arron at 6k. But my secondaries start to slowly **** at that point. Carpenter racing is currently working on this problem but any info or insight on how to get around this would be greatly appreciated. I’m hitting 210hp just under 6k right before we watch the secondaries close down.
