ill start this out with some info
95 kx 250 stock except for a pro circut platumin pipe. Fouling new plugs dead every 15-20 min.
Things ive tryed to fix it
I have repacked the silencer (stock),cleaned the carb,checked the pipe for clogs,
used maxma super m, kawasaki, spectrol, bellray, oils all at 32.1,40.1
50.1 and 52.1 mixed with highest octane pump gas. Tryed stock and hotter plugs and
resister plugs all ngk as well . Put on a new oem spark plug cap. made sure there
are no grounds loose. Cleaned the flywheel and stator. Checked the
power valves. Checked the reeds. Checked for vacume leaks.
Checked the carb jetting which is stock at 160 main 45 pilot.
cleaned the air filter.
Put choke on and start the bike turn choke off after about 2 or 3 seconds crack the throttle a few times and ride.
This bike runs great till it foules the plug. and believe me i keep it on the pipe.
Amd it doesnt make a diffrence if im riding it on open ground or in the trails.
Runs great and just dies even if im in the throttle and wont start till i put in a new plug.
Buddy i ride with has the exact same bike. Same carb jetts same everything and does not kill plugs at all.Tryed putting my dead plugs in his bike to see if they will run and there dead.
not a altatude problem
I can ride his bike all day long and never kill a plug.
Amy ideas ??
