Arctic cat 366 smokes blue

Recommended Posts

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?

      Hi All,
      Hoping someone will be able to help.
      I have a 2006 Kawasaki Prairie 700 with twin Keihin Carbs CKVR D32. The Rear Carb is leaking out the side during cranking. it is not the float bowl overflow. It is on the opposite side of the carb from the diaphragm. 
      I got this bike not running and someone had already messed with it. I took the carbs apart , cleaned and rebuilt. Everything went pretty easy.  It looks like it could be missing a small tube between the carbs but I have all of them listed in the service manual installed. See the pic for where it is leaking from...
      Any help would be much appreciated.. Thanks.

      I have a 2018 Kodiak 450 EPS that just this past Sunday I ran through a bit of water.
      After the puddle the belt was slipping, so I pulled over and drained the ultramatic housing and the slipping problem went away. This was all in L and everything seemed to work fine. Later when I got on a road, I put it in H, but it still rode like it was in low... i.e. I had to rev it up a lot just to get to 30mph.
      When at home I pulled the ultramatic cover off to inspect, and it looked okay in there. Not much dirt, belt and everything are clean, but when I rev up the engine (with cage in place, of course), the belt doesn't get to the top of the clutch (maxes out about an inch or 1.5" from top of clutch, so maybe it is normal).. I put it back together but same thing... H seems like L still.
      Do you think the clutch needs to be further dissected for cleaning, or could this be an issue with the gear selector?

      Hey Guys, 
      I picked up my first ever ATV on friday. It's an 89 Big Bear. It has some cosmetic issues, but seems pretty decent mechanically. I did have trouble getting the idle tuned to the book spec of 1,300 - 1,500 RPM. I took the carb apart and cleaned it out. Somebody must have lost the spring for the pilot screw, as it's no longer in the carb. Also, I have a dual cable carb, I noticed all the IPL's show the single cable carb, but I see others on youtube had dual cable carbs. When I would adjust my idle speed screw, nothing would happen. I bottomed it out and it didn't seem to make much if any difference. When i pulled the carb apart I saw the screw doesn't even touch the linkage, it's too short. Do the two different versions have different length carb screws? I'm wondering if somebody lost the ordinal, replaced it with the IPL number for a single cable carb which is shorter, and gave up on getting the ATV to idle. If you hold the throttle just a bit to get it to the RPM range listed above, it "idles" great. Any ideas? Or any links to the dual cable IPL?
      Have you guys have good luck with the aftermarket intake boots? Or is this a buy once, cry once deal? I'm guessing the OEM units last longer, but there is a huge price difference. If you have had good luck with aftermarket, where did you get it? My current boot doesn't seem to have any air leaks, but it's encased in JB weld... 
      I'm getting a 9th digit check sum error on the ATV when I put the VIN in. Has anybody seen this before on a Yamaha? The VIN  number looks original as well as the paint around it. 
       
      Thanks,

      I have bought a 1996 suzuki king quad 300 and I have noticed that it smokes but I have put oil in it and plenty of gas had to fix shifter bc the nuts and bolts came out somewhere. I have had to replace the wire for the starter but now when I try to start it it wont idle at all and when it does run it smokes really bad like a whitish blue I guess, and it likes to stall a lot. So anybody can help me out please and thank you
