i had a pro circuit t4 full w/ k&n filter with lid on and used a 105 main jet vs. the stock 98 main. the hmf slip on is prob as good as the PC full plus cheaper. i ran the pipe for a little without jetting and deffinately got more throttle response after bumping up the main. i also had 20in razrs. pipe, filter, jet, and 20s will perk the lil 250 up.
