Dyno Results Testing New Pipe

Results for dyno (true rear wheel, which is about 25% less than crank). With Vespa pipe and one custom built for Vespa KDX. Did not have correct jets to finish tuning so power and top rpm will be higher. We used wide band oxygen sensor and it worked a treat, we are running way lean so larger main jets are required.

Red and Green runs are with powervalve set to low rpm power. We do gain some power but not enough to worry about.
