I have a 2000 Polaris Xplorer with the 250 two stroke motor
It does not want to start with the electric start, the motor cranks fast, the battery is good, and there is good spark when cranking. The engine starts perfect when using the pull cord, it even starts if I pull the cord slowly and starts with one pull. The engine idles smoothly once started. My wife says she needs the electric start to work.

Bought this quad a couple days ago. Got it home and couldn't get it started. Got my new starter and recoil on. Starts up great. Took it for a quick spin hot light came on. Guess my question is there a way to test the sensor? If sensor is good what would be next step? Any other common checks I should do before throwing new parts at it?
My son’s 17 Alterra 500 just quit today. It was running fine the started stalling and bogging at half throttle. It finally stalled and will not start. The bike was won in a raffle last year. It had sat for a year before he won it. Has ridden it very little since. It has 180 km on it. We checked the plug spark seems strong disconnected the fuel line at the pump and the fuel pump is working well. Disconnected the injector and it is spraying fuel. Air filter is clean and there are no mouse nests in the air intake. Al fuses checked and good. Ideas?

Changed fuel pump, has spark and good compression. Tried a gravity feed trick and still couldnt get it to fire off. But it does try to crank when i spray starter fluid. With pump connected and fuel hose off, it should still pump fuel, correct ? But its not. And i cant find anything online about this bike. Has less than 200 hrs, so barely gets ridden (wifes). New fuel in tank. Any suggestions would help. Thanx....

Hi there everyone. Just seeing if there is advice on a problem I have before I start digging too deep.
I recently bought this creally nice 2004 King quad ltf300 with only 2400km..
Everything things works great except when engaged into 4wd or diff lock it has a clicking noise ( sounds like broken teeth etc) are the front diffs known to blow? Or the transfer from engine?
I am yet to test on some loose ground to see if I'm getting drive at front .
I will be driving in to find problem in next few weeks but thought I'd see if anyone might know what it is first. Cheers

I have a 2013 KQ I bought it new but rolled it a few years ago. I have replaced the left lower A-arm and left tie rod, the steering is still a little sketchy as I just eye balled the alignment. But the major issue is the left front tire cambers out at the top and has wore the tire bald. Tires have about 2000 miles on them but other 3 are half tread and left front is a slick.. I can not see anything else bent and don't know what to do..

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
