big T, u know good and well that bike will spin those tires and if u wanna spinem betta you know what needs to be done-/a clutch kit will help a considerable amount in pulling abilities....as far as everything else goes it just depends on how much power you want...you may even wanna put 29.5x10 on the bike/then you would definitly need quite a few mods to spin them as well as you would want....its your bike, do what you want//dont get a jet kit if you decide to rejet. all you need is a bigger jet from the dealer and u may need to ajust the needle but that is all-plus itll save u like 30 bucks so that will work out great.
that bike should turn them fine...those things are beasts (still dont know if red 500s or 05 or 06 650 is what I want) are you gonna ride with em in the spillway this weekend? I wont be able to go caus ma bike still messed up and too hard to get it too the shop during the week with skool in baton rouge and everything
