simple, send it to Jim @ Jim's performance (look at my sig) and he'll have it done and shipped back in no time.

I would leave it alone, if you raise compression you going to raise piston temp. and your going to have to rejet

thanks for that just thought i would look into it see what it would take. Have you guys seen any power gain in removing the black silencer thing in the exhaust

Leave the sound suppression it will get louder and you lose top end on the xlt you want to replace the intake grate and seal the pump shoe for safety first, the stock grate is not safe i have pictures in the project section of my ski with those mods being done. depends how much you want to spend to go faster jims ff plate is a great investment to get more speed and better ride some get 3-4 over stock on his plate. welcome and gl with your ski

IMO, Milling the head and aftermarket F/A are a very good mod combo to start gaining more power,and this should be done together with jetting.
About milling, Not all machine shops have the knowledge to do it properly on this type of heads. It's not as simple as shaving some material, it also involves cutting some angles on the squish band...
