I have an 01 300ex and it smokes a bit not horible but it does. And i have asked again and again if i can rebuild my top end and my dad always says no he doesnt want to mess with it. i am fully capable of disasembling my atv and removing me engine and taking the top end out and apart. i need help convincing him, and how much would it cost to get it bored?... help plz. pistons like 80, and could i do a high compression piston ( 11-1) on pump gas with out other mods? thnks
