The inline fuel restrictor is very popular with lake riders, since it only leans out the rich top end. Supposed to add a couple HP, but seems sort of risky to me.

that's sort of what i was thinking,but they do offer a wide range of jets

I recall reading about them in SnowTech either early this season or late last season. They seemed to like the restrictor.

I installed an injector perfector on my 09 m8 and i cleaned up the mid range and top end, you just install it 8 inches away from you fuel rail and it comes with some jets start with the biggest one and work you way down (keep checking you plugs of course) it works great i have speed werks y-pipe and high flow intake and rave exaust valves. have about 300 miles on it no issues. i also ride it at home and in the hills.

Man, I thought fuel injection was supposed to cure all of our carb problems. Now you have to "jet" your EFI. I dunno.
