Maintenance & Technical > KX500 Original
Jetting!!! Again and again and again!
kxpegger:
190? Didn't even know they made a jet that big?
Andiracer:
Even when i look at the altitude information...i can not go that low to have such main jet :P
I found 168 in the user manual July 2000 and 175 in the service manual. So it has to be more less in that range.
Now i need good wheter because at the moment we have snow and ice.
sandblaster:
The manuals can be very conservative.
I run 168's in both my relatively stock K5's.
However, that number can go higher depending on what carburetor, pipe, port work, reed, port timing, head cut,and other mods you are running.
The best thing is to watch your plug color...
Andiracer:
Test run today :-D
Pilot jet should be adjusted because no idle possible.
Main jet is way to big but bike already feels great at full throttle!
YEHAAA!
Andiracer:
Impossible to get the bike idle:
Testrun today on asphalt.
Settings:
Needle: N82M middle position
Valve: 7
Airscrew: 1.5
Main Jet: 175
Pilot jet/Slow jet: 58
Fuelmix: 32/1 (Found that in the manual...). Should i use 40/1?
Changed it to 52, 55, 62...idle not possible. Have a 60 but did not try.
Carb is clean. Engine warmed up but did not drive for some minutes.
What im doing wrong?
