Ok i just got the complete exhuast. I also got the needle and 170 main jet kit they offer. What notch should i put the clip on when putting their needle in? Stock position? :yfz

try needle clip postition 3 or 4 and the 170 main jet should be too rich but it will work. I run the JD Jetting kit with a 168 main 45 pilot and 2 turns out on the mixture screw.

Sparks recommends the 170 main with the YZF 450 dirt bike needle. not too sure about the clip....

I bought the 170 and needle togather that sparks recomends which is most likely the dirtbike needle. When i pin the gas while not in gear it bogs down. I need to know what they set the clip at

try to turn the idle a little higher and see if that helps

Setting th eidle higher isnt gonna clear that up :disgust

um yeah it will. Outlaw and everyone else. The FCR carb that is on this quad is a pumper carb which means it has a little lag off idle. No biggie you dont ever need to go from idle to full throttle unless you are trying to impress your friends or something.

Has anyone gotten rid of this lag? I find it hard to believe that everyone has this problem. Mine seemed to get better when I rejetted to 45 pilot. Has anyone tried a 48 pilot? I also have a slight pop when letting off the throttle making it seem as if it is lean on the low end. Thoughts?

 

[PapaHilly]

yes a backfire would most likely mean you are lean. move your needle 1 more clip.

 

[edgerat]

A slight pop on decel is fine. You can thank Yamaha for the ACV on the carb for your backfires on decel.
