Cams for milder build: HC intake, E exhaust?

Recommended Posts

So despite the roller coaster my own DRZ-SM build became, the Dude has decided he wants his own SM. We may have already found a bike semi-local but I have some questions.

This one, if we do anything to it, probably won't be a big build like the last one (bored, stroked, ported, 41mm carb, WR gears, MRD pipe). I'm thinking something much milder like the PB/Q4, E or HC cams, 15/38 sprockets, maybe the 39mm FCR. After the headache of the last, we just want to ride. :thumbsup:

My question is, I've read several places where folks are mixing up the cams, putting the HC intake and E exhaust into their bikes. I can find the HC specs pretty easy, but am having a tough time finding the lift specs for the E. Is there a reason to go for the E exhaust? One thing I was told was that the HC exhaust didn't always allow hot gases to vent well, or is that another issue altogether?

Like I said this is all speculation at this point but it's something I couldn't find in a search. Is there a benefit, for a medium build, to mix-and-match the cams? Or would all E/all HC be about the same?
