Maintenance & Technical > KX500 Original
Jetting!!! Again and again and again!
Johnny 5:
86 500 , looking for starting point,mostly concerning needle.
This is a Mikuni carb. Was/is this stock for 86 ?
Owner bent original, then lost it :roll:
Parts place he went to said they couldn't get stock needle. So they got him a
6N1
6FJ6
6F15
Which would be closest to stock, and/or best to Start with with? Pro Circuit pipe and aftermarket air filter are only mods.
Also, what fuel and mix ratio is recommended? Getting close to firing this beast up !!
Foxx4Beaver:
the stock needle for that bike was 6J6-2...
as for which one is closer to stock, kinda hard to say without having a stock needle to measure, to compare to the three others.
I myself would just pick one (like the 6F15), and put the clip in the middle position, and try it...if you think it could use improvement, then you have the other two you can try as well, just be sure to put the clip in the middle position on the other two as well, so that you keep things consistent....and do some plug chops to see how it's burning.
Andiracer:
Hi guys.
Just bought the bike, cleaned the carb and found this settings:
Needle: N82M middle position
Valve: 7
Main Jet: 190
Pilot jet: 58
Heard that the engine was in a Bike with Side-Car bevor. Could that be the reason for that big main jet? Standart is 168.
Any ideas?

umberto:
What altitude are you riding at? Is it a stock bore motor?
Andiracer:
Had Aprilia RS125, RS250, Husqvarna 125, 150 and 250, KTM 380, Cagiva Mito...Go-Ped. Never changed jetting because of the altitude to be honest. My place is @431m
Motor is stock. Has a new Piston and new crankshaft bearing.
I will do some test riding after i have changed oil. Then i will test first the 190 and then go slowly down. I'm curious if i will recognize some difference.
