Have you gone to the HMF web site? They give you the break down on what you have to jet your carb too. I run a HMF slip-on on my 400 and I had to rejet the carb a couple times from what the website told me. It all plays in the altitude you are at too.

dont reply if u dont have the correct information... or anything close to it. Anything that changes air flow will require jetting. Its all about mixing gas and air correctly

[Mr_Bub400ex]

of course it will add powerr and u will have to rejet

It will deff sound faster ;)

And it takes more air to make that sound so I guess it would need some larger jetting too. :D

i am runing a 118 main jet and the needle on the 4th clip, that is with the hmf slipon, and a white brothers header. it has notcible power increase all over. it is worth the money and looks good.
it sounds awsome allso. i would say go for it and get a white brothers header while at it.
