If you look up the hotcams specs you will see they arent much different than the E. I havent used a set so i cant comment but my E cams let me pull til the rev limiter and ive got more bottom end grunt.

I got a pretty good deal on some klx 400r cams for my z from ron ayers. they are just relabled e cams. 2003 is the year you want to look up if i remember right. Hot cams are just as good from what i here. Although i wanted factory grindsl

One thing that isn't often considered.

Hotcams are degree- able, E cams are not. Not something many do, but worth considering if you want as much as possible out of the bike, without going 470

Personally, having tried both, not much difference at all. Feels as if there is more mid with the Hotcams, but not put the Hotcams on the dyno yet

I was really surprised with the performance of the E cams (haven't tried hotcams). I didn't figure I would be able to notice much seat of the pants difference, I was wrong.
