Im getting jets and a hmf pipe for christmas. The pipe i can do with no problem but the jets I no nothing about other than they are needles that go in the carb. I have friend who is a mechanic that says he will do it for thirty bucks. Is it hard? Can I do it myself and save thirty dollars or should i let him do it? If some one thinks it would be easy enough for me to do and wants to tell me how it would be great thanks.

its a piece of cake. Go take a look at your carb, you have to unscrew the 4 screws on top to replace the needle, thats simple. then flip the carb over and change out the main jet, the only tricky part to this is, disconnecting enough of the stuff to get some room to flip it over to get to the bottom. 4 more screws here. Save your 30 bucks and take a shot at it. Its really quite simple to do.

If i can do it, anybody can. I'm not too mechanically inclined & i did it with
no problem. The fella's on here are real helpful. Give it a shot.

its simple as tieing your shoe, most of us with the 500 use the dj170 when i put mine in i did just as the instructions said with the air/fuel ration screw screw in till seats then back out 2.5 turn ran like a top no adjusting at all.

thanks ill give it a shot. to bad i gotta wait a week.

Those of you using the DJ170 to jet your 500's...are you running a stock or aftermarket exhaust? I have a SuperTrapp exhaust and was wondering if I could install the same jet. My dealer wants $135 to install it and I'm almost convinced to install it myself. Thanks for the help.

most everybody who is running the DJ 170 is also running a exhaust(most are HMF's) also running a different air cleaner either a uni or a K&N

its the whole more air in and more air out means you need more gas

Wow Mullet, you almost sound like you know what your talking about.

But he's right. More air out needs more air and fuel in. Is he going to jet the bike (installing a jet kit) or is it just a pipe install?

You can do the jetting/install your self in a hour or two, if you are a complete novice.

Definately get a high flow filter if you add a pipe.

Mike, you almost sound like you know what you're talkin' about .

Ok, I too have no idea on jetting the carb on my 500 Foreman. How many jets in the carb need to be replaced when you do an exhaust upgrade? And the DJ170 jet you are talking about is it just for the HMF pipes or does it work or other aftermarket pipes that fit the 500? I read a few things on some jet setting is Dirtwheels and it talks about there being like 4 jets that can be changed in a carb, I am all confused!! Is like the main jet the only one that needs changed? I too am looking to upgrade my 500 Foreman and would like some Ideas on where to start.
Thanks for any help.

 

[Robb]

all you need to change is the main jet 99.999999999% of the time. With the 500 the 170 jet should work with most exhausts, filters, snorkels.

I did it today to be honest i found replacing the muffler was more of a pain doing then jetting. I just disconected the carb from the motor and the air box then i disconected the gas line and the line that runs into the airbox flipped it changed the jet and set the mixture screw like it said flipped it back over changed the needle and the spring and reconected every thing worked great. the muffler was a pain to get off and get the new back on i dont think it should be called slip on but beat on. none the less its all on and works great thanks for the help guys.
