I've got RT ones, and KN filter plus Dyno jet kit. I followed the jet kit advice and ended up with 185 front and 190 rear on the mains, with needle clips on 2nd from the bottom, as per the kit advice. I also have a Flow Commander unit fitted which allows me to ajust the air flow through the main air jets. (This has the same effect as changing the needle position, or the main jet to some extent) The bike dynoed at 105.3hp first run but was way over fueling on the main jet circuit (air/fuel ratio shot to hell). With adjustment of the Flow Commander got a better a/f ratio and 108.9hp but still way to rich. The dyno dude suggested dropping a couple sizes in mains, even back to stock at #175. So I went back to 175 front & rear. Bike runs smoother, pulls hard and has impressive top end. Not dynoed yet but seat of the pants says I hav'nt lost any hp or mid range grunt. More fuel does not always mean more power.

with just jardien high mounts i made 105whp/67wtq. I have since did the jet kit and filter didn;t notice to much difference in power, but overall def smoother.

 

Hey AMF Racing
What size jets and needle position are you using?

Reb

 

I have staintunes on mine with the factory carb kit & it got a lot more power to the top end & mid range but lost out in the low reve range I went through the pilot jet size from 50s to 48s but the std pilot jets seem to be the best in oz needle clips on the 4th ring & std main jet size seemed to pull the best at top reve on & off throttle but you have to play around your self to fine tune

 

i can't remember off the top of my head, been a while, but i used w/e ones they said in the directions that came with the jet kit for the mods i had done....
