2007 Arctic cat 700 efi atv smoke

Recommended Posts

I just bought my first arctic cat. I changed the oil and filter. Now my atv smokes only when u rev the engine. Smoke looks white grey.. slight light blue tint.. when it. Idles it doesn't smoke.. Any body have a clue what is going on. The dealer said it's not the rings.. it has the 700cc suzuki engine..

when ones burning oil it will smoke when you get on it, or smoke worse then, its usually the rings or valve seals. it could be a bad gasket, clogged crankcase vent, but its usually rings or valve seals or both, I just sold a arctic cat with a 650 kaw v twin with just over a thousand miles that did the same thing, I sold it cheap as is because the last one I had that did that, a Suzuki quadmaster 500 with 1700 miles, cost me so much to fix,

Thanks Bayou Bill.. what's really wierd is that it started after I changed the oil. Th eoil was black. I just bought it. It. Didn't smoke prior to oil change. It only smokes while I rev the throttle a couple of times. If I just rev it steady from low to high it doesn't smoke.. weird. . U would think the rings would smoke all the time... the smoke isn't all that blue. It's more of a grey color. Like seafoam look when u add it...

I buy quads and fix them for resell in my spare time, I have bought several that had clogged carbs, valves out of adjustment, etc, that would idle all day without smoking, but when I clean the carbs, or whatever and get them to really run, smoke when you get on them, some a little, some bad, the quadmaster 500 would idle fine with no smoke but when I got it running right it smoked like a tar kettle, only on acceleration though. I had to replace the rings, piston, cylinder, they were all wore out, I put new valve seals in it too and lapped the valves, but the problem was the rings and cylinder, the nickel plating was worn through in one spot and the rings had around half thickness from new. in general in a car the rings will smoke when cold and get better when hot, and vice versa for the valve seals but ive found quads don't always work that way. anymore if I get a smoker after I get it running I sell it cheap even if I lose money on it. of course if I had a quad I wanted to keep and wasn't worried about profit I would fix it.

      I'm wanting to run Shell Rotella T6 synthetic in the 700 Griz but I can only find it in either 0W-40 or 5W-40 weights, and the manual says it's ok to use everything BUT those weights...5W-30, 10W-30, 10W-40, 15W-40, 20W-40 and 20W-50.
      Would it be ok to use the Rotella 5W-40 or do I need to stick to what's specified in the manual?

      AL righty I did some trading around this weekend and ended up picking up a few 4 wheelers for cheap. I ended up with this one for $500 in it total and well the guy told me it dropped a valve. I haven't really messed with it at all. But this weekend I am going to try and start working on it some to get it running before winter time frame. So what I am asking is a couple of questions.
      1. First off where do I start I tried pulling the pull cord and could not get it to move at all.
      2. I need to get a service manual for this 4 wheeler where can I get it downloaded for free?
      3. what do I need to look for and how do I go about this really. I do have experience with 4 wheelers but this one is a little different to me than others because its a V2 and I have no clue where to start internal on the engines. Most of my experience is on the outside portion of troubleshooting on theses wheelers.
      Please no smart butt answers as i am new to here but just wanted opinions on where to start. Please and thanks wink:
