If you have the stock tires still . . . yeah. I can't remember which project site wrote it. but an amatuer rider improved his lap times by 8 seconds with mx tires. Your blaster will be easier to slide and more fun to ride. I like the Klaws but Holeshots are great tires also.
take it slow bud. remove your tors, get mx styled tires, remove your airbox lid, get a uni filter, get a port/polish, vforce reeds, flip your front rims, full exhaust. Any one of these will wake your blaster up. Just remember to rejet with any intake/ motor/ exhaust mod.
I would get the tors removed(free), put on new shoes($100), filter / remove lid ($20), rejet ($3-$10). Ride the biotch till ya get enough for a pipe. the trees will be a blur in no time.
