if you are running a dyno jet kit w/ dyno jets deffinantly a 175...
That is the dynojet size. Last year when my bike was stock with a hrc cam, vennom pipe , K&N filer no air box I was runnig a 175 main at florence all year. so thats a good place to start, u may drop to a 170 if u r running a airbox. Good luck. There is a dif between the kehein jets and the dyno jets. If u dont have the jets let me no I got 2 full sets that I dont need anymore.I see most run anywhere's from a 170-180 main jet on the 2005 R.
Is that a dynojet size or is that the standard kehein jet 170-180 main?
I understand there's a difference.
Are you talking 180-170 dynojet or a regular Kehein jet from the shop?YOu probably should be anywhere from 170-190. Some bikes are different and require a 190. But most need about a 180-170 with your mods.
