How Many Miles

[cajunbiker]

How many miles should I put on the new K9 250 before I change the stock exhaust? I have a new set of baffled B52's I was considering installing & how do I determine if rejetting is required.

Zero miles needed with the stock pipes. Jetting change is likely

Depends on what type of pipes you're going to install.
