124 with zilla 66 vs 58 . Customer is a bit odd and wanted to run the bike at a low RPM range chug alone etc .. so all in all he should have bought a 585 LC engine. But tuned first with 66 , then it was swapped to the 58 .. Posted this on another site turned into a $hit show over not a real test etc .. any ways no changes other than the t/b and air cleaners I did make pulls with no air cleaners on both units and there was ZERO change in power . so air cleaners did not effect it. 66 has odd bolt pattern so you are stuck with a few choices.

This 124 was super quite no piston noise and ran better than most .. numbers aside looking at the curve you can see where the smaller unit did better with THIS build
