I just put the DJ170 in the bike seems to not rev up all that smooth, but I didnt try for very long, its a little loud for the neighborhood What are other people running for jets in the 500s. I got the HMF, snorkel and k&n. Thanks.

I run the DJ170 also. Mines fine. Maybe you have some dirt in your carb. Also another buddy of mine has the pipe and jet and his bike seems really sluggish. Mine was that way also but seemed to wake up at around 170 miles.

I ended up with the 170 jet, but without the stock washer. And the air/mixture 3 turns out.

seems like it is still fine with the snorkel on but I only ran it up/down the street once. didnt want to get popo involved.

I wil know tommorrow afternoon but there is no wifi set up in Holipaw yet

The reason is that the new motor has a hemispherical combustion chamber. A HEMI HEAD. It flows alot of air and fuel.

ok so heres the question ..
did you guys notice a power gain with the jet kit?
i put mine in - tried different jets and all, noticed a little bit of power gain,
but unreal fuel comsumtion! i mean like WOW ! drank more than me !!
its back to stock jetting with the K&N.
just wondering what other peoples results were.
i came to the conclusion that it was WAYY to much fuel for the very minor power increase.
on my rancher ir worked great, wasnt too happy with the kit on the foreman though.

I seem to be getting real good fuel economy with mine so far. I know riding with Eurobro, his drinks about twice the gas mine does.

Robb did you get your problem solved?????.... I found something interesting about my buddies 500 foreman... He had his bike dynoed and he has the DJ kit,UNI, and the supertrapp.... Hid bike made 12 hp at the wheels on dyno and the mixture was way out of whack.... So upon further investigation it turned out that DJ had sent the wrong needle.. which that tore up the needle seat inside the carb and that is why the bike ran so sluggish.. They installed a new seat and correct needle and the bike picked up just over 4 HP.. finishing at 16.4HP at the rear wheels. The price was stiff though...A $50 dollar dyno run turned into $435..OUCH. But the bike runs perfect now... Now he just needs to learn to ride it LOL... He sunk it the next day.. Carb is full of muddy water..OH well.

Yeah I got my issues all worked out. The 170jet was it for me, I didnt try anything else. I am going to pull my plug saturday have a look, but i seems to be running good.
A 190 jet, that is massive!!!
