yes i would deffinitly get a jet kit i would suggest a dyno stage 2 that's what i have and it works great. it will be ok to drive it a bit with no jetting changes but the sooner u get the kit the better.

should i be worried about runnin to lean before i jet it? and how do you tell if your runnin lean?
