new to the forums but am trying to jet my raptor done a lot of searchs on the topic but no luck.i have a 2002 raptor with a trinnity pipe K&N filter. I put the jets in that trinnty sent moved the needles and runs good at low end and good on top end but a little hesitate in the middle. My elevation is 6300 feet any help would be great .This is going to drive me to drinking[img]i/expressions/face-icon-small-confused.gif[/img]Iam so close its killing me!! Thanks to all!!!

 

Did Trinity know what elevation you were at when you bought the pipe? If it runs good low and good high your problem is somewhere in the needle clip position, if memory serves me..

 

I have tried to move the needles it is on the fouth clip from the top right now that seems to be the best spot so far. the third clip it seemed to run out of fuel and it just fell on its face!on clip higher and it ran like crap.I do belive that trinnity knew my elevation and i think they were close but it needs some minor adjustments hopefully someone is around my elevation and we can compare.

 

WHat will you be drinking? I'd like some Wild Turkey and Diet Coke myself.

 

That sounds like a good before bed drink!

 

Hopefuly someone will chime in that has similar mods and elevation. You might call trinity and ask them. Also post your main sizes, clip positions you've tried, pilot sizes, and fuel air screw adjustments so everyone will already have your information, also is this a stock mount K&N with the lid still on??

 

my needles are in the forth clip from the top and i have tried all other spots except the 1st and 2nd positions.jets are 160,160.K&N filter is a pro design with the lid off.I have not messed with the air screw yet. Thanks for all the help[img]i/expressions/face-icon-small-smile.gif[/img]

 

sorry i am a good typer the jets are 160 165

 

Sand I'm at 5200 feet and running the Alien and dynojet stage 2
no lid 140 142 DJ mains needle 3rd from top A/F 3 turns runs perfect
I think your little high on your main for mukuni jets for 6300 I would try the
150 155 and see how it runs there

I have the Yosh pipe, not the trinity, but maybe this will help a little(here in Oklahoma,not sure on elevation S. E. Ok) I have the full yosh pipe, k&n filter with billet adapter plate conversion, airbox lid in place with all of the crap cut out of the snorkel. I am running 160/165 mains, clip on the 3rd notch from the top. a/f screws are 3 turns out and it seems to run very smooth and strong.

If I were you I think I would move the clip to the 3rd notch, and play with the a/f screw, start at 1 1/2 to 2 turns out and increase by 1/4 to 1/2 turn at a time. Be sure to put a little bit of grease(not much) around where your filter clamps on, just extra insurance against dirt invasion. Good luck.
