Default Cams in a 103
After a bit of research I find quite a few recommendations for 211 cams in a 103. HP/ torque numbers from anyone with hands on ? Or any other cams you've put in your 103 with dyno sheets and experience to accompany would great. Thanks in advance.

Where are you getting those recommendations from?
211 is not suited to stock compression bike and if you had the mods to support a bigger cam with higher compression, there are many newer cams than the old 211 that'd work better.
What work has been done or proposed for your 103 engine ? Riding style etc?

Quite possible I'm wrong, bike is bone stock except a Bassani RRII and SE breather and tuned. I probably ride it like i stole it or a bit harder than I should being that I'm accustomed to riding sport bikes...not a stunt rider but I might give some wheelies a try sometime. I just want more hp and torque than the 83/104 I currently have.

Im currently doing a 103 build from a 96 ci. I went for S&S 583 cams based on discussions I had with S&S, Andrews, MoCo and one other supplier that I can't recall right now.... but the S&S 583 seemed to fit the bill. Guess Ill find out for sure once the build is done

My second 103; first one was 111hp/117tq, but not nearly as nice for touring
