I used the Zoar and I ran a stock cast muffler instead of the TurboHeader. I never saw the TurboHeader make 600 rpm's worth of difference, 300 on a couple of engines but mostly 210 to 260. I'll play some more today. Adrain is sending me a whole system for the Saito 100, I am going to put it on the high compression .80. I'll have to space the sensor up about 1/8th" because the cam box on the .80 is the old pre-B engine design and is shorter. Should be a piece of cake. The prop drivers are the same. Yep, I made a piston stop and an adapter to hold the piston at TDC with vacuum. I am a regular old hand now. The main problem is keeping Honey Do's from interfering with the important work.

That article I removed was about 3 pages long and of no use to anyone, it concerned the setting up the chassis on a Vincent Black Shadow. Apparently adjusting the sparkplug wire length would alter the handing characteristics.
