Ok I need help someone anyone! Got a 2016 sportsman 570 with code 102 4 that won’t go away! This is what I’ve tried so far 2 tbap sensor harness 3 tbap sensors (Amazon) Rebuild fuel pump (kemso) Whole new fuel pump assembly (didn’t build pressure right) Quantum fuel pump New fuel injector...

UPDATE So after replacing battery and relocating voltage regulator and replacing the spark plug with iridium spark plug and new relays the code 102 4 is completely gone seems like but now I can only get the quad started if holding the throttle I can go down the road and back no check engines...

Hi all, Bought a used 2007 sportsman 700 EFI about 2 years ago and ever since I had it, it has been producing the same problem but getting worse over time. I have tried everything i can think of to resolve it. The quad used to generally start up fine but if i let it get too warm and idle then...

2005 Sportsman 800 EFI Have ongoing issues I cannot resolve. Replaced broken fuel pump and machine was running great. After two weeks of good use, while idling in my driveway it killed and wouldn't restart. Now will start and run for a few seconds but kills as soon as I touch the throttle...

Rode the bike 2 weeks ago with no problems. Today the bike will not start. There is no pressure in the fuel rail (checked the shrader pressure relief valve). The bike will start on starter fluid but only for a few moments. I checked the fuse and relay (both are good) I'm thinking the fuel...

Hi guys, The voltage regulator and the battery melted while driving. I replaced those but I'm still not getting power to the fuel pump. Any suggestions? Thanks in advance for any help!

I have a 1997 Sportsman 500 (non HO) if it sits it's hard getting started especially in cold weather it will run the battery dead before it will start at times and when it fires it fires for a second and dies, and it takes a few times before it will take off. I had cleaned the carb when I got...

I have a sportsman 1000 xp. Ran great parked for approx 2 weeks now will not start. Went straight to fuse got no power on hot side of fuse. If I send power to fuse it will fire up an run until I take power away honestly I'm a little puzzled any help would be greatly appreciated!!

Howdy, lots of reading but first time posting. I bought a 2004 Sportsman 600 twin with only 50 hrs on it a while ago that was running really rough and with only the choke out. I stripped everything down, ended up buying a new Carb for it. I put everything back together with a new fuel filter...

My 2005 predator 500 was barely starting and if It did would run rough. After looking into it I realized it was a bad fuel pump and disconnected the lines and ran a line from the tank straight to the carb to get me by for now. The quad ran great for hours with no issues. Is there any need to...

I'm a new member & hope I'm posting this in the right section to help others. Symptoms...bike would idle fine...no engine codes...when cold it ran like a bandit...as soon as the fan come on it acted like it had a rev limiter and would tach 4950 rpm's and no more...funny thing no bogging...

Good day all, newer member here looking for some guidance before I bring my bike back to the dealership. Great forum BTW… Anyways, I have an issue with a random no-start on my new 2014 550 X2. This no-start has happened twice so far and now I cannot trust the bike for fear that I will not make...

Hello. So I'm still fighting this start on ether an run on gas problem. I tested fuel pump and if I turn the key on it quickly jumps to 19-20 psi. If I turn the key off it holds pressure and builds to 39 psi on second turn of the key. Is that normal? If I hit it with carb cleaner it fires up and...

seems to be one problems after another with this quad but im working my way though them and its getting better and better. Previously ive had absolutely no issues with the fuel pump, its always worked well. however, I recently removed the carb and gave it a good clean out (which was well...

As many others have reported, I had similar problems with the engine randomly dying due to fuel related problems. Most of the time, the engine would start, idle and run without incident. Then, while riding, without warning, the engine would die. I used a shot of ether ("Engine Starting Fluid")...

Went threw everything got spark air all that now not getting fuel is there a fuel pump or is thre hoses that get clogged if it sits for a year or two? I replaced thw filter aswell . Thanks

Upon hooking up the battery leads the fan and fuel pump immediately start to run. After reviewing the schematic it appears as if either the ECU is malfunctioning or the fan and power relay are welded shut. A bit of history, it appears as if one the ignition cable (spark plug cable) shorted out...

Hello, I have a 2007 Sportsman 500 EFI with about 200 miles on it. The other day I went to turn it on and the digital display starts going wacky (technical term, right?). It's cycling off and on, all the normal electronic startup sounds repeating all over again. However, I can't actually...
