Maintenance & Technical > KX500 Original
Jetting!!! Again and again and again!
Foxx4Beaver:
I wouldn't go from the middle position to the top with the clip...that's too big of a jump at once....try the 2nd from top to start to be safe.
I also agree on finding the correct needle for THAT carb...the N82R...I probably have something within a couple "steps" or two of the "R"...I might have an N82P. I can send one to you if you can't find one.
umberto:
I am going to do a leak down test this evening to see if that is the problem or not. I'll let you guys know what I find. I won't lie, I'm pretty nervous about doing it. The last thing I want to do is tear this motor back down again.
Rocky Mountain has the N82 in K, L, M, N, and P. Any thoughts on which one I should get? The N and the P are in stock, the other ones they will have to order. Should I also update the pilot jet? The stock one is listed as a 55 (I have a 50 now), but they have 58, 60, 62, and 65 in stock.
I really appreciate all the help. I'd be lost without you guys.

As it was the wrong needle fitted i did not see any harm on trying it {though it would be like 1369n on 3rd clip ] , try every clip position if he has time :-D.
Since he got that motor on ebay, the motor might never have ran with that carb[jetting}
probably better off trying a good working kx500 carb even thought the jetting on the 88 could vary a little due to bigger case volume
Foxx4Beaver:
I'd snatch up a "P"...
don't buy the pilots or main jets from Rocky...they are NOT genuine Keihin, even though they're listed in the OEM Kawie parts fiche/diagram...they're cheap bootlegs.
Buy the mains and pilots from here....

they sell Genuine Keihin jets.
you can buy the needle from Rocky, it'll be genuine.
