I was reading another forum recently about fuel leaks and possibility of fire happening. Reminded me of an incident I had a few years ago while working at a Can Am dealership. The quad was a stolen & recovered Outlander 650 that had been tampered with. These quads have an electronic safety system, similar to their DESS system on the sleds. You cannot bypass the key switch and get spark without a computer with factory software. Anyway, I was trying to determine what was damaged since the thief had attempted to hot wire various electronic parts. I got all the extra wires removed and things looked back to stock. Pulled the spark plugs and was going to check for ignition and if the starter still worked. Well, they both worked alright and guess what - the cylinder was flooded with fuel! Instant flames with gas spraying all over...great!! I managed to use my hands to put out the fire, good thing I had on gloves (but choked they were ruined of course, haha). Seems it's possible to flood an engine with efi when you put power straight to the injectors, doh! As in much of life, you cannot take things for granted (I'd only seen carbs flood like that). And even though it had spark, the quad still needed a new ECM to run - that part alone was $1200. So lets hear your stories, crazy stuff happens every day I'm sure.

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

I bought this four-wheeler used for my son's birthday last week. It wasn't running when I got it but after a new battery and some tinkering it has been running for 5 days probably 8-10 hours of run time.
Today after 1 hour My son wanted to wash it, I showed him how to be careful not getting water near the engine. We were careful but after we washed it and let it dry the motor starts but the transmission slips and won't really go forward. Even if I pick the back of the four wheeler up the wheels only go forward a tiny bit. It's as if something is slipping inside. But it worked fine right before the wash.
Not sure what brand. I was told it was 90 cc's the VIN is attached. Is it 90 or 110ccs?
No air filter came with it. Using a some old stockings until I figure out what air filter to order.
My son is so bummed so I want to get it back up to speed but also teach him how to work on it.

Hi, I’m a 16 year old that is wanting to get more into vehicle and mechanic repair. My dad has an old ‘96 Timberwolf that he doesn’t remember running since I was born. I want to get it running again as a memory for him and to help us be able to hunt together, and of course so I can learn how engines work more than the little information I know now. I’ve pulled the carburetor and gas tank off of it, and the carburetor is getting cleaned by a friend. I can post photos of the condition it’s in later, I’m just curious where I should start in my journey to get it running again. The power switch is broken off of the handlebar, so I am looking into fixing it, along with the pull cord. I’m afraid the engine is seized up, and I’m curious to hear any input anyone has. Thank you all.

New arctic cat owner, I've read alot on the gauge issues, but let me say I have power, good ground, the aux also has power, the memory has correct voltage but no output of any kind. Only the LCD color works. I have also fully removed EVERYTHING and cleaned it all... what I still possibly have a cut wire knowing that I have good power to the back of the plug and good ground to the back of the plug but no outputs of any kind?
