Default Dyno Jet Grizzly 660 help

I just installed a jet kit & k&N filter in my griz. Lots more power but hesitates when i initially take off (noticed mostly up-hill). Once I am riding it works great. Womdering what setting i should screw around with first? I used the recomended jet by dyno jet. Also wondering if slider setting has something to do with it.

from off idle to small thottle would be your air screw, from small to mid thottle would be the needle on the slide and from mid thottle to wide open would be your main. hope this helps good luck.

so i would play with the air screw bit and maybe you will have to adjust the needle also.

the instructions on the jet kits are pretty good must times.

Anybody with personal experience with this? what did u do? does the order of needle jet spacers matter or on wich side the spacers are placed on the e-clip?

yes the spacers matter on the bottom they would raise the needle and your motor would run richer more fuel, less washers and the needle drops lower and your motor would then run leaner. did you try adjusting you needle or air screw yet.

If you follow the inst. to the t you should be ok. you may have to mess with the air screw + or - 1/4 turn from 2.5 turns. Make sure the needle is set up per jet kit inst. also use correct jet for elev.

ok, the problem is when i took the spacers and e-clip on the old needle off i wasn't paying attention if all three spacers were on 1 side of the e-clip. I think 1 spacer was below the e-clip (large metal spacer) and 2 where above e-clip (plastic spacer and small metal one). so if your fuel screw isn't ajusted corectly this will cause hesitation? As I start to accelerate, the grizzly stumbles for 2 seconds then drives great. Do you think my mixture is to lean or to rich. pain in the poop to adjust carb, would like to be more edjucated by others before i start foolin around.

try adjusting your air screw first thats the easy way, maybe you can loosen the clamps and turn the carb a little not sure what your setup is for your machine.

Check out this site www.yamahaofsi.com I have checked it out and it shows the needle as from the slide it goes metal washer ,plasticwasher (under clip),clip, metal washer. I had the same problem when I went to put mine back to stock , I could not remem. how it went.Hope this helps.
