I want to to order a jet kit for my Baja, and I have found 3 options. Dyno-Jet Jet kit on e-bay, and an FMF and K&N jet kit from Rocky Mountain the Dyno Jet kit is about 54 bucks, the FMF is about 53 and the K&N is bout'44 bucks. What do you guys think???

Thanks,
Tom

 

Save your money and put in a mikuni #175 main. Set the factory needle to the richest position (bottom groove). Air screw out 3-4 turns. Leave the air box lid on! I have dynoed many combo's and this one works very well.

What kind of jetting set up for a 2004 Baja with K&N filter & FMF Powercore 4 pipe at sea level?

 

Also mainly dirt trail and track riding.

 

JMAC, set it exactly the same.

Thanks MisterHP,

I went to my local dealer, non-bombardier and he claimed that mikuni dose not make a 175 only in 10's (170,180,190) where do I need to look?

Thanks,
Tom

 

Eric, the mods must just delete ALL PM's sent to you because I sent you one. But I'll post it here for you:

I read in the jet kit thread where you said to use the stock needle in the richest position. Now I have the DJ needle on the leanest position and that's where it runs the best by seat of the pants feel. Should I just leave it alone or used the stock needle like you said? What is the advantage of the stock needle over the DJ needle? I figured it would be the other way around... Thanks.

 

Thanks, I'll give it a try. Right now I have it at a 170 main jet and the needle it the stock position with the mixture screw at 3 1/2 turns and it flys.

 

Are the jets large round, or large hex type. Or dose it matter, Maybe that is why my local dealer could not find a 175 because he was looking at large hex type??

Thanks,
Tom

 

Large round. Typical dealer, gotta hold their frickin hand with everything.
