Flow Test Comparison

Haven't been on here since Moby Dick was a minnow. Had my first look at a Kaw 1100 Zephyr head yesterday and flow tested it. Too bad you can''t bolt those to a KZ. With some work they'ed really wake up that engine.

Here's a comparison chart to look over.

Black Line = stock KZ1000 with 36mm Intake Valve
Blue Line = stock 1100 Zephyr with 39mm Intake Valve
Red Line = same KZ1000 head but ported with J Model 37mm Intake Valve

Nice. Do you expect the exhaust side to be better as well?
