Sean. The problem with Megacycle that I have seen is they use a small selection of cam masters. So, hard to get the gains for engines of various configurations. Usually, cams get you that last bit of power in a race application. A street bike with no bump in compression could even lose power if the cam's duration is long enough.We've used the Megacycle cams with welded lobes for years with no issues. The drop in cams added a sum total of 3 hp I think. You need modified pistons and other work to get an real gains with any cam changes.
