450r Jetting

[mattonln]

I just bought a K and N filter w/outerwear. I plan to run it without airbox cover. I have only the HRC muffler endcap. what kind of jetting should I run? I got the FMF jet kit and it recommends around 180 MJ with needle on 3rd position and 2 turns on the air/fuel mixture. is that about right? I live at 800 feet... thanks!

i used a 180 main ,replaced needle and some tubes in airbox and motor hrc lid kandn filter stock end cap. not sure how much that loud end cap helps, i put it on at racers thats all.
