Working on a bayou 220 that has been ran extremely hard it's whole life. Literally had almost an inch thick dirt/oil covering the motor. Yeah that bad. Surprisingly it runs though. I cleaned the carb and tank multiple times. They're clean enough to eat off of. Readjusted valve lash and set timing. Was about 3 teeth off. It cranks good and runs good only problem is I have to cover the carb intake basically choking the hell out of it for it to start. The com choke works fine. It does this each time I start it regardless of temperature both ambient or motor. Wth? Compression is at 115psi I get 130s if I put a little oil in the piston chamber. Please help. Thanks

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

Does anyone know what the 3rd item is behind the battery on this ATV ? I know 1 is the, solenoid1 is the CDI box, what is the 3rd.

Hello again guys ,. I have a Quadmaster that has a very bad lean to my passenger side wheel. I replaced the a arm bushings with no change in the lean, I see no bent parts and no adjustments available. It's always been there since I got it but became really noticeable when I put the lift kit on it. I'm going to add a picture of the problem if allowed.

I have an older 1980s Suzuki quadrunner red lt 4wd (250)
so just finished putting it all back together and was running fine just needed to adjust the rebuilt carb
bf decides to hook up an air chuck to the gas tank because it got a shot of air in the gas line well 120psi didn’t agree with any of the parts including the new carb
end result : new battery new carb now it just clicks (one single click) won’t turn over
hard to pull start gets hung up (unless I remove the spark plug ) gas flooded out the first time but now does nothing purchases a new starter waiting the arrival
could there be damage to the crank shaft or pistons etc? Or install the new starter and try to fire it up ? What caused the starter to die after he flooded everything with gas was working fine.

So Id say about 2 years back I bought a 2013 Polaris Sportsman 500 H.O. off of my uncle. It ran perfectly, nothing wrong at all. I usually go mudding with it or just ride trails with buddies. So as you would assume, the quad is quite dirty from sitting for a few weeks.
STUTTERING PROBLEM: I noticed one day out of nowhere that in high gear at 15-20 MPH, I was already maxed out at 4500-5000 RPM It would get to 15-20 mph, max out on rpms and start sputtering. It sounded like it was basically acting like it couldn’t go any faster than this.
IDLING PROBLEM: I was fucking with the carberator the other day maybe thinking that is causing my sputtering, and now my idle will shoot up to 2600 on start usually, then I will turn the throttle adjustment down to the normal 1400. The rpms with then fluctuate 10-30 rpms back and forth repeatedly, it will then run for about another 30-60 seconds and the RPMs will slowly drop to about 900-1000 RPM and stall out. I replaced the carburetor and everything seems to be working perfect on that, no leaks and what not but it’s still acting strange. Also, I’ve noticed that when looking into the Electronic Throttle Control that two plates that aren’t supposed to touch have to be WAY past touching to even try to fire up. Even when set at a wide open throttle like that, I still have to give it some throttle to get it to fire up.
Here is what I have done so far:
Checked the belt and clutch
Changed out spark plug (Last one was covered in carbon)
Cleaned the intake and air box
Replaced the carburetor
Replaced the inline fuel filter
Checked that all lines on carburetor are connected into the right spots
Checked If intake boot was cracked (Not from what I can see)
Unhooked and reattached new carburetor (About 4-5 times)
Cleaned battery terminals and battery off
Shut on and off Gas Line Cutoff Valve
My next thoughts are that maybe the TPS is fucked up or maybe the Spark Arrestor is plugged with mud. I was thinking tomorrow to purge the exhaust and also check the ohms output on the TPS.
ANY HELP IS GREATLY APPRECIATED. I HAVE BEEN BATTLING THIS FOR WEEK AND REALLY WANT TO GO RIDING. THANK YOU!
