[QUOTE="jerryme72, post: 942988, member: 62522"] hi,i got a 91 kdx 250 a couple months ago.it was in pieces as the previous owner wanted to paint the frame,anyway.i got it all back together and it ran great after taking off the airbox lid (it was starving for air).than the bike started to foul plugs after two or three rides-ngk br9es.i am running the bike @50:1 with 10w30 in case.so i went and got a couple different plugs br8/br7'the 8's lasted longer but the 7's the longest.i didnt want to go hotter after the 7's kept fouling.before i rip the bike apart to check crank seals or to see if anything else is the culprit---are there any suggestions for the cause of this plug foul problem like electronic or my fuel mix or anything at all..any help will be apprieciated.thanx jerryme also when the new plug is installed the bike runs xxx-cellent...
