What can I do to tune my 03 500 HO up? Is there an actual adjustment that will affect the speed as far as timing? I understand that there is a limited adjustment but will it actually make a difference. I want to know before I pull the right side cover off and play with it. I frequently ride with 700's and 800's and of course they're faster but I'm talking waaaayyyy faster. I have a clutch kit and am running itp589's, 26". I expect to have lost a bit of acceleration but My HO is a dog....Thanks
