96 Polaris Xplorer 400 2 stroke tuning result and walk around by Z's Power Sports 

Your correct. A extra rich condition on a 2 causes the combustion chamber temperature to plummet which doesnt allow a complete burn of the oil in the fuel. Look for worn or incorrect carb jetting and parts

I ditched the Vm34ss carb that was on it due to wear. I purchased a mikuni vm34-275 i used the oem needle and cutaway slide and the needle clip at the very top. I used a 200 main, 30 pilot, and a br7es plug. This smoothed the transition through the circuits and made this machine very trailable even in extreme terrain. The plug is a tan color under any riding condition with the original expansion pipe

The gas guage is made by a company called kelch. Its not 100 percent accurate but give me a good idea of where my fuel level is at.

Thanks

If you are referring to the pilot air screw i have that 1.5 turns out. The mixture on the pilot circuit plays a big role in how the engine will respond to idle speed adjustments.

@@timothyzeimet4972 dang I ended up having to go back down on my jet because it was running like crap even at 1.5 turns out

So the fat needle will run the fuel transition way too lean. I can get you the needle number i used on the xplorer. I do remember it was gold in color. Going to be doing a big shop update video today on a lot of scrambler upgrades ive done recently. Very exciting stuff. Thank you for the sub.

@@timothyzeimet4972 your welcome. I was at the polaris dealer today and the parts guy told me the needle that belongs on that carb is a , 6-DH29.the atv is stock otherwise. What brand winch is that ? And the switches on the dash must be for the winch? Thanks

Jet needle in my particular build is a 6CEY6. Slide is a 1.5.

The switches on the hat allow me to control the reverse rpm limiter in foreward gear for extreme offroading where reduced power is sufficient. The other switch allows me to bypass the rad fan on when crawling strenuous trails continually in low gear puts a strain on the cooling system.

The winch is a badlands 3500 zxr with a kfi industries winch mount.
