      Arctic cat 366 smokes blue
      By 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.

      Warrior 350 air filter mod
      By Rick Shropshire
      I recently picked up a  2000 warrior 350 and it doesn’t have the air filter box so I was thinking about using a clamp on filter directly on the carb.  Anyone know what I need to get or where I can find it? The one I ordered goes in the box and won’t fit directly on the carb.

      Yamaha warrior has severe loss of power after installing an air filter box and new filter
      By Need-help-with-quads
      So I picked up a 1995 Yamaha warrior a while ago and it ran decent with quite a bit of power, I was able to wheelie like nobody’s business, but I noticed that the air filter box lid had bunch of holes drilled in the top and hole in the side, also the air filter itself was serving no function and there was a huge rip in it. So I got a new air box and new filter and when I installed it, the quad lost all power and acted like it was cutting out for split seconds at full throttle. For reference I think it was running rich before because it would backfire a lot so I think it’s just restricting air flow, but how would I adjust to that because I tried leaning out the carb as much as I could but it didn’t seem to do anything unless I put the other airbox lid on with the drilled holes.
      any help would be much appreciated
      Also even when I put the old lid on, it seemed like just the new air filter gave it enough restriction that it still wouldnt run right
