So I have a 2010 Ultra with 4in Reinheart slip ons. I have a K&N highflow air filter I'm putting in and plan to decat the head pipe. How far can I run the bike without worrying about the possibility of hurting something. Got about a 250 mile trip to get it to my buddies place to get it tuned. Thanks

 

Go ahead and ride it, you'll be fine....

 

Best thing to do is install the exhaust but hold off on the a/c until you get there this way you minimize the leaner/hotter running from more air entering without more fuel to compensate.
While the system is closed loop it can only do so much before it runs out of adjustment.
Good luck,
Bob
