86 LT250R Oil Fouling.......

My 250 keeps oil fouling plugs like crazy, I think I went through about 20 plugs last time I had it out. Tried mixing gas 32:1 and 40:1 no change. Thought it could be engine oil, so I ripped it apart and replaced crank seals. No change, still oil fouling. Any Ideas?

your probably running(jetted ) way to rich in your carb ,get some iridium plugs(br8eix) too once you get it jetted right.iridiums cant foul ,your in need of going down on your main jet a couple sizes most likely.

bump the amin down 2 sizes... both 2 sizes down a 1 size down.. then experiment with that... oh and mix that oil leaner... try soem amsoil dominator at 50:1 get ahold of me for some... i haev yet to foul a plug running amsoil.. and believe me my old 370 engine ate plugs for breakfast....... switched to amsoil dominator and whalla no more plug problems..
