I have a stock 15 XP1000 and I love they way it runs. RPM,s are fine. Excileration is fine. It is just good the way it runs In stock form.

My question is if I go to a 30" tire what will be the ill affects as far as performance. What will I have to do to make it run like it does now?

How much of a loss in power and excileration will be noticed going bigger? Not so sure I want less power, if you know what I mean.
