you will be able to wind it out a bit more for sure. mill the head and jug install a wiseco prolite and good reeds and you'll really turn lose an animal. this is the same combo I run and mine can make a KX250 work hard to pass me. gets a little pingy on pump gas though in the dead of summer (august)
