I just upgraded my exhaust and breather. And the only way to get the motor to run smooth is to program it at 103 with cams. So my question is. Is there a way to tell what has been done to the motor without tearing into it?

 

Not a lot of info here. What is your bike and motor and what are you using to tune it?
Unless you can ask the previous owner you just might have to pull the heads.
Welcome to the forum.

 

09 street glide motor is off of a 11 v&h large radius short exhaust screaming eagle cone type intake

 

I was thinking the same thing, the only way to know is to tear it down, or tune it and ride it hard, who cares whats inside just ride...

 

You have to know what all is in it...just so you can brag and post all that crap in your signature...silly rabbits...

 

Did ja finda turbo?

 

If it runs fine after the program, don't be concerned. If not, get a dyno. Good luck.

 

Even if you open it up, there's no guarantee you'll be able to just look at it and be able to tell what has been done to it.
