I will do the dyno tests on my small ATV dyno. Same dyno all my stock cyl and cubs are done on. I run 19" tires with 17-39 gearing. The dyno passes will be made in 6 th gear. I will be checking AFR on each pipe. I will do a as cast set of runs and a ported set of runs. Domes will be a pump gas setup. Same domes will be used for all testing. This may not be the best for all pipes but its a general test. Cam
