02 ZRT blowing through gas and very little power

My ZRT 600 ripped a few weeks ago during the blizzard. Had a ton of power, fast as hell and ran well. Got it out this last weekend, topped off the oil, gassed it up and it started out ok but ran through 10 gallons of gas while my other sled (800 polaris) hadn't even gone through 1/4 of tank. Refueled and it ran through another 10 gallons (full tank) before my Polaris was even on a half tank. In fact, I actually ran out of gas the first time before I could get back to the truck to refuel.

It was bogging down terribly but was running. It would just take me to feather the gas to get the power up and once I got it going down the trail it would sporadically have a ton of power like it was sputtering or something. Basically, it felt as if it was missing or plugs were fouled or something but the issue of the ridiculous amount of gas concerns me.

Checked the plugs and they are in bad shape but I don't know where to start looking into the gas issue as that seems the real problem here. Please, any thoughts you may have for a newbie would be much appreciated.

The plugs show that you are definitely running rich, and it sounds like it is often running only on 2 cylinders. those 2 things together will add up to terrible gas mileage.

first thing to do is determine which cylinder is not firing consistantly. If you pull off a plug wire and run the sled. you should be able to tell. If it runs way worse, thats not the cylinder, If it doesn't seem to make much of a difference, thats the cylinder you need to work on.

Next, check to see if you are getting good spark to that cylinder. the problem could be as simple as a bad wire or spark plug cap. If you are getting good spark, then you need to look at the carb. check to make sure the Choke plunger is not sticking, and clean and adjust the carb if necessary. If you did not do it before the season, you should probably consider cleaning all the carbs. Also, you may need to look at rejetting. Sleds need different jets for different temperatures and altitudes. A jet that is right for 0 degrees will run way too rich at 35 degrees.

One last thing, with the way those plugs look, it's pretty possible you just have a fouled plug. So, before you do anything, you should try a fresh set.

check the compession in all the cyclinders... im guessing that middle one "popped" those tripples are bad for loosing the middle cylinder.. if it sounds like its running on 2 cyclinders it prolly is...

Best thing to do is pull all the carbs and start disassembling them one by one. This will allow you to check EVERYTHING and clean each one properly. Make sure you do a very thorough cleaning and inspection.
