Cams have been discussed in recent times on the evo forum, so take a look back through recent posts. My EV27 was great (I moved onto bigger motor now) and is used by many of us.

Andrews EV 13 is also a good choice - works well with a stock engine at stock compression levels, provides more torque from 2000 - 4500 rpm where many folks spend the majority of thier time.
Agree that if you are going to replace the cam, that you really need to replace the cam bearing with a torrington B-138 , it is much better than the stock INA cam bearing and will last a lot longer with running a new more gressive cam.
J&P sells the Toirrington B138 for 6.99 and the required cam shims to properly set the end play on the new cam for 2.99 a piece.

I"m running an EV23 on a stock EVO with K&N air and Supertrapp 2:1 exhaust. Good pull up to 5K. I'm on an Ultra Classic. For your bike, an EV 27 or Woods 6 looks like a very satisfing cam by a lot of users.

Did you use the stock cam gear or the Andrews gear? I ask because on the Andrews site they go through gear lash measurement. If your gear that comes with the cam has too little gear lash, the result is a whining noise, if the gear lash is too loose it can result in a more noisy valve train. The whining is a definite bad thing, can overheat the cam, the gears, the bushing and the bearing, plus shedding metal particles into your engine. The other, while annoying, is much less harmful. When I installed mine, I measured but only with a digital caliper which was only accurate to .01, should be measured to .001. The result was the whining. So I switched back to the stock gear and now the valve train is no more noisy than with the stock cam.

Sounds like you had a bad experience. Mine was just great! Only reason I changed it was I wanted even more performance, so had my motor stroked, ported etc.
