jetting?

[#927]

i have an 04 450r with a full lrd pro 4r exhaust and uni filter and im having trouble jeting. right now im useing a 185 main 50 pilot and needle on the 4th clip air screw is 2 and a half turns out but it doesnt feel right it . any suggestions on how i should jet it would be helpful

Are you using dyno jets or keihin jets? if your using keihin jets i would try a 180 and if you have dyno jets i would probly use a 170 because they would be around a 180 in keihin jets. also if you have a dyno jet needle i would move it to the third clip. hope this helps

im useing the stock needle and keihin jets ill give the 180 a try and see if it helps

yea im not an expert at it either thats why im asking for advice

[450rRacer22]

yea i'd give the 180 a try, if that still doesnt feel right i dont know what to tell ya. leave the 50 pilot in for sure, that helps with the back firing on deceleration and the idle. are you runnin with ur lid off?

[#927]

yea the lid is off

alright, then a 180 main, 4th clip on needle, 50 pilot, and 2.5 turns out on the air/fuel screw should be about right then.
