Arctic cat 366 smokes blue

[spigmef]

I bought a 2008 arctic at 366 with 120hrs. When i red line it in neutral is smokes blue a lot. When I put it in high range it has problems getting over 35km/h. I bought it and had to clean the carb. It ran ok after i cleaned it. Not I have this problem.

Blue smoke is a sign of oil getting into the combustion chamber. Could be seals, rings, or other oil through the intake.

How is your air ruler, is it oil soaked?

air rulers fine. I cleaned the carb again and just before the carb there is an air box. The box was FULL OF DIRT. I cleaned it out and it runs great but still smokes blue. I'm thinking sand or dirt got into the cylinder and scored the cylinder walls.

So the air filter is good? You definitely don't want air restriction. Could be that sand or dirt scored the cylinders.

Should I just leave it and check the oil level every once and a while?

Ok so I definitely need to redo my rings because today I started it up and it smokes really bad. Does anyone have a price on how much this costs if I do the rings myself?

you can get rings for 20-25 on ebay its not too hard to put them in if you download service manual
