yzf400 both hotcams???

I want to get the exhaust hotcam with the auto decompressor but was wondering if it is worth the extra $ powerwise to buy both and is it noticeable power?


I think even on the hotcams website they state that performance wise these cam are intended for use with an engine that is larger than 400cc.

How about with a 420 kit with 13.5 compression?

A guy from hotcams is a member of TT his screen name is, wait for it.......... hotcams, maybe you can send him a PM and ask him.
