2008 500 Artic Cat and Bad Gasoline

Recommended Posts

First a hello to all. First time poster as I just recently found this forum.

I have a 2008 500 Artic cat that recently had to go into the shop. Problem was the carb was gummed up from bad gas after sitting for several weeks. I always use Sea Foam and Sta-bil as a stabilizer and figured that was all that was needed but apparently not. Couple mechanics at the shop made a few recommendations for when I knew the cat would be sitting for several weeks. One was to put a fuel cutout valve between the fuel pump and carb and close it and allow the engine to run until it quits. Another recommended to just drain the fuel bowl when parking it. Yet another said high octane gas will stay stable a lot longer than the regular unleaded. Don't know if that last one is true or not. So the meat of my question is do any of you have any tricks of the trade to preventing this problem as my cat does stay parked for long periods at a time, especially during the winter months. Thanks..........................

Ride it more. Sounds like a sarcastic joke but I assure you it's not. Start it up, warm it up and find an excuse to ride it a little...

  • take it down the driveway to check the mail
    borrow a cup of sugar from your neighbor
    get a snow plow mounted and keep your driveway plowed
    put a snowmobile suit on the wife and take her out for pizza

Seriously though, finding reasons to start and run the quad is really the easiest way around the winter fuel challenges. Running the quad more often will also prevent you from being that guy asking this question when Spring comes..."Hey guys, I let my quad sit in the shed for 9 months of winter and now I think the battery is dead. The dealer said it'll be $90 for a new one...can this be right?"

By the way, yes, that's right.

The other thing I have been doing is only putting enough gas in the tank that I will need for the planned ride. If I know I can get by with half a tank I just fill it that much and I only buy gas the day before the ride. I think the problems with ethanol mostly involve water separation. The other additives should help with the rest. I have used both sea foam and marine stabil but never used both at the same time.

Welcome to QUADCRAZY!

Definitely start it up once in a while and leave minimal gas in it.

Appreciate the advise. It's not like I don't ride it at all during the winter....just not that much. I keep a trickle charger on at all times when parked and even during those times I don't ride much I start it up every week and let it idle for a short period, sometimes only every two weeks but it's not like it is shoved in a corner and never ridden. We had a unusual heat wave this summer where temperatures were in the triple digits for 9 weeks and I'm thinking that may be the reason for the gas to go sour so fast.

Senator.....at 68 years of age I don't plow snow from my driveway......I hire someone like you to do it for me. This problem occurred during the summer months so it wasn't from not being ridden as often during the winter.

Once again, replies appreciated...thanks.

      I bought my big bear in 2009, never had a bit of problem with it until last year. It quit starting but still would click when I tried to start it. I replaced the solenoid, the cdi module ( it was burned on one corner) and this year replaced the battery. I have all lights but still will not start and I do not have the clicking when I try to start it. Can anyone give me any ideas what to try next? I haven't had any luck finding videos about the 2008 Big Bear. I'm trying to avoid the expense of sending it to the shop.

      Picked this beauty up for zero dollars this weekend. It has been passed around several of my son's friends and the last kid was just tired of tinkering with it.  Mostly complete 96 300FW. The pic is my boy robbing the swing arm and rear diff for his 300 for a big memorial weekend ride. Wiring is garbage at the battery, kick start doesnt work, no coil, smoked like cheech and chong when it ran last. I figure a couple hundred and a few hours and this will be ready to ride. Journey will be documented on Instagram at @martincyclellc if ya wanna follow along.

      Hi all,
      Picked up my first Brute Force yesterday. What should have been an awesome afternoon of riding turn a bit into a deception. As I was unable to really take it out for a test drive at the shop, I decided to buy it and agreed that I would take the test drive at home. 
      When giving full throttle I noticed that the Brute was choking and lost all of its powers. Faulty fuel pump most likely. 
      Called the shop and the are coming to pick it up and repair it and bring it back. Good service. Nevertheless feels a bit sour in the mouth as I was told it was a 100% good. 
      Need to have some patience I now before I can really start riding.

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law
