Here is something I never thought to ask. What is the size of the engines in these dyno runs? Particularly the ‘PERFECT DYNO’. the reason I ask is because my run, the crappy looking one, did not change much after I made the mods and then had a dyno jet guy check to make sure I didn’t screw it up too bad

I have a stock engine for 06 TBA. The only mods I made are TOR pipes, FREAK, 150 mains, TBS needle(no shim).
He balanced the carbs, turned the screws and tightened the chain to fine tune. (he said a loose chain would give a wavey dyno chart…
Anyway… the chart looks pretty much the same except smoother and a bit more hp. I will upload it once I scan it…
