Jetting!!! Again and again and again!
nirvanafan98:
Loved reading the Engine Chart and Carb tuning. Just learned a lot can't wait to try it out. Have 87 500 mods, Pro Circuit pipe a reed spacer and stock carb settings. Just rebuilt top end . Smokes to much, plug wet . Going to check timing then adjust air screw. Run 32 to 1 Bel -Ray. Maybe try 50 to 1 . Been using Bel- Ray since the eighties when I races Moto in HighSchool . :-P

Hi Guys, I just picked up a mint 1985B1 KX500 with a Mikuni VM40SS Carb, and was looking for some basic / sea level jetting specs? :?

which performance makes the bike?
to lean? (white sparkplug)
to rich? (sparkplug looks always black and exhaust is wet with unburned oil)
ideal is when the plug looks dark brown ... only other info i could give is on this website in the parts-shematics.
www.cmsnl.com
oem-needles for the 85 are no more available. jets you could buy by any mikuni-shop for the mikuni-vm-carb
but never forget, if the bike performs well, dont change the jetting... :wink:
