jordan, what main jets are you running, that's making you feel that you have to big of jets? is your sled rejetted for some mods or something?
jordan
New member
yeah he had it jetted for alot of mods including pipes and cold air intake but it only has the cold air intake now it was running 170-165-165 for mains now i put in 165-160-160 and its better but im thinking if i go to 160-155-155 it should be close to bang on cuz right now at 165-160-160 if i pull the filter off it revs out but with the filter in its about 7500 which is up from the previous 7000rpm with 170-165-165

those are way way big jets for just a cold air kit. what is your elevation and riding temps and is it only a cold air kit? or is the airbox gutted/modded too?

1500 ft anywhere from -10 to-30 during the same day haha and as far as i can tell the box is supposed to have three tubes inside it and they have been cut off

-10 to -30 in ferenheit or celcius?
the lid under the foam filter is all stock? no extra holes and slots cut in?

thats celcius and that lid is stock just the two narrow slots
That's a lot of jetting. Why the 2 size jet jump on the last cyl? I'm ported, piped, CAI and I run 155/45 across the board.

jordan

if he was racing on grass or something in summer would it be jetted higher like that or no

the plug in the hole jetted 170 was dark but the other two dont have much color yet as the plugs were just changed
jordan said:
No It would be WAY lower, Like 135-140 MAX! Warm air isn't as dense as cold air.

That's BC you had WAY to much compression and needed to cool the cyl at the same time with the high jetting.
yep but did a ride today and it run awsome fix the heads run 160 and wooohoo it fly ....stupid but i gain like 300 rpm with heads fix and switching to 2001 ignition
