Like KeithB I am interested in some day getting an EVO along with my current scoot. Do these all have only one cam? If you do a cam change I assume you have to buy an EVO specific cam? The twins have chain or gear drive, what's the EVO setup?

EVO's since 93 (I believe) have cams with zero overlap. EPA wielding their big sword. Andrews, S&S, Crane, etc....All make good cams for the EVO. I haven't checked lately but at one time there was a SE cam also available.
The cam sits behind the 'cam cone' and is gear driven. They come from the factory with an INA bearing, which you should definitely swap for a Torrington. A cam swap is a fairly easy procedure, if you've got the JIMS tool for removing/installing the inner cam bearing.

I had a SE686 cam,& went with the Andrews EV3. More mid range power,what a difference
After some research it was the in 1992 that The MoCo started bending to the EPA on their cams. One of the options for EVO owners was to swap in a pre 92 EVO cam.
I have to say that the SE air cleaner + Cam + pipes + re-tuned CV carb = a HUGE difference in the way the bike ran. Truly felt like I was riding an 80" bike.
Shortly after buying this bike I installed an EV13 cam, HI-E4 ignition module, and Thunderslide kit (185 main, 42 low jets). Everything else is stock. Since then I haven't looked back, as this is a great setup. Low and midrange torque is excellent and power stays on 'til 6k rpm. Gas mileage averages around 54 mpg on my last few trips, mostly backroads with speeds at 65 mph ot less. It's an excellent setup for heavy bikes, but if I had a Dyna or Softail I'd install an EV27 instead.
Yes, EV-27 kicks a$$ on the Dynas and FXRs. I put one in my '91 FXRP and there was a considerable difference. The bike being a police bike originally, already had more power than a stock bike.

Looking at some CA cams they are in the - * of over lap, but yes EVO cams are for the single cam only set up. If you are stock take a look at cams that are going to wokr with compression ranges of 8.5-9.1 The andrews cams work well as do the cranes, comp cams. Huge selection of cams to fit every riding style and compression ratio.
