How much horsepower would a 250ex gain with these modifications... And list how much HP each modification would give, I already know the HMF so just help me with the others.
K and N airfilter
outerwears
HMF pipe - 4 hp
HMF jet kit
no airbox lid, not really sure if the no airbox lid adds much more hp but w/e.
