I put a high flow airfilter on my bike, and last night I put on a set of Ultma drag pipes. what is a good way to tell, or how to rejet.

 

Was the bike modded before you added the aircleaner and pipes? If it was stock you will need to rejet it.

Thank you, that link had a lot of info on it. and yes it was stock when I got it.

 

You will notice a difference when you go up 2 or 3 points on your jet...you gas mileage will decrease but the fun factor will increase.
