Regardless the cv1 made more power.

87 cc E-head converted by Butler to their CNC wideport and then touched up by Knowlton.... starting out life as an 87 cc head, definitely would've held them back a few horsepower compared to a 72cc head. Interesting read though. I believe all involved tried their best.
