can anybody point me in the right direction i live in uk and own a 03 raptor iv pur a yoshi slip on on ,k&n with outerwear ,stock air box with no lid what jets do i need and how many turns on the pilot i havent started it yet it is stripped in gagage waiting for the jets to arrive

 

What is your altitude and what brand of jets did you buy? Need to know those things first before offering advice.

 

Yeah what he said, but if your only replacing the jets and using stock parts in the rest and your near sealevel. 160/165 mains and about 3 turns out on the idle mix. screws.

 

i have not recived the part yet i bought them on i net waiting for them to arrive(im not into politics anyway between the two of you ) i will let you know when i recive the parts

 

No politics between us, both trying to help. I asked what brand of jets because the numbers are different for Dynojet than they are for Mikuni (stock). You can't mix the needles and jets between DJ and Mikuni.

 

the jets i recived are dyno jet and i read the sheet and it said 144/146 for my sea level and 3 turns what do you think boys

 

Did you get the DJ needles also? As I said earlier, you can't mix DG jets with the stock (Mikuni) needles. You might be a little lean without the airbox lid running 144/146, you might try 146/148 and check the plug after a full throttle blast. Don't be afraid to try 144/148 either. With the full Yoshi, K&N with no airbox lid, my Raptor ran very strong with 146/148, needles on the 3rd clip (from the top), and the AF screws at 2.5 and 3.

 

ye suppleid with needles and it is only a slip on yosh what do you recon mate

 

I agree somewhat.....since all carbs are somewhat different from the factory on their calibration, I would recommend backing the A/F screws out 3/4ths of a turn COUNTERCLOCKWISE from their current location.

 

i have turned the screw out 3 turns from closed is this ok do you think with i think the jets i pur in are 144/146 i can tri it carnt i this is to dyno recommendation what do you think
