What are some good upgrades for the impeller and intake grate on an 04 sportster? I would like to have better out of the hole acceleration but I don't want to lose any top end speed. Any help would be apperciated, thanks.
I would put in an intake I think they sell for 230$ thats good for about 5hp I'm sure, pump wedge I bet would help out a tone on the jetboat. Not much else you can do with an NA unless you want to spend some money.
