Dyno Follow Up

Well, after more dyno work, I have two more bikes in a good state of tune.Pierre's bike is up to 60 hp. This bike has my high comp pistons, 750ss cams, and Bruce Meyers heads. A homemade exhaust system was killing his top end, to the tune of 6 hp! I strapped on a wide open Conti headered open magaphone system and instantly got it up to 60 hp.


















My bike is very similar to Pierre's except for 900ss cams and a full Conti 2 into 1 system. Note the results. 67 hp/45 ft lb! Those 900ss cams are the hot ticket. The other run here is the same bike with a 2 into 1 with a smaller diameter secondary pipe. The Conti 2 into 1 has a secondary pipe length that is tapered, which obviously works better.

Thanks again to Andy Palmer at West Coast GP Cycles for dyno help.
