You hear a lot about ev27 cams but there is an se11 available down our way and Kees was asking me about it but I have never fitted one. How do they compare to the ev27?

 

It's been a while but last I heard the SE 3 was about the same as the EV 27.

I don't know about the SE 11.

 

Here you go, it's for lighter bikes
This is the next generation SE-1 bolt-in cam for lighter bikes. Advanced profile design, creates power from 3500-6000 RPM. This is an awesome horsepower cam in a bolt-in disguise. Unless specified, not for use on EFI models.For Race Application Only!
Note: 1340 Cams over .510” lift may require case and/or tappet guide machining for cam lobe clearance. 84-85 model’s pistons may need to be fly-cut to obtain proper clearance. Please refer to instruction sheets and service manuals for more details.

From what I read it's similar to an EV 51. Could lose a little bottom end unless you bump compression.

 

Thats whats in my Dyna with 9.5:1 Weisco's and its fun.. Cant compare it to the EV-27, I've never ridden one, but it has plenty of power in a useful range. Just by seat of the pants, I'd say it may lack the very bottom end, tire smoking torque, but it comes on pretty hard and loves to run until the heads run out of air.. 80mph is very peppy and a slight twist will clear 90 very quickly.. Anyhow, thats my "feel" dyno report..

 

looks like a good to very good cam. Kushman's paste though makes me leery of it being a direct 'bolt-in'. anything hi-lift simply ain't drop and go.

 

Just to give you an idea, the dealer dropped the cam in mine years ago. The did change the pistons to 9.5:1 flat tops, but no work was done to the heads until recently.. My guess is they are bolt in cam's but need the compression to realy come to life. I'd suspect 10:1 might be more ideal, but tuning would be critical to avoid detonation..

 

Thanks guys, I think the Ev27 is better suited to his RK though.

 

I ran the SE-11 cam in an 89 Evo FXR with 10.5:1 forged pistons. Enjoyed the broad torque range and high RPM HP so much I installed the similar profile SE211 cams in my '03 TC FLH
