loud pipes save lives
Ok from the sound of it when i leaned mine out a bit it sounded to hit about 17.000 stock spec rpm is 15.000. And the o34 stock should run 14.500.The coils in the 026 are unlimited, no problem to run them up to 16,000 rpm anyway. I was told by another engine builder that they got 20,000 out of them.
