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

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.

Hi guys I'm in the market for a new ATV. I narrowed my choices down to King quad 750 Grizzly 700 and Rubicon 520, I own a 2006 500 Rubicon right now and I like the reliability and power for plowing. However it is not a capable ATV. When quading with other guys it falls short with ride quality and ground clearance. I also have a 500 King Quad 2015 which I like and will keep it for my wife. It is very strong and reliable also. However my plan is to sell my Honda Rubicon and replace it with a 2020 of one of the these mentioned above. Can anyone give me their take on one or all of these machines and why you picked what you picked?
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.

The Hop-Up: You may be saying to yourself, “that’s a chick bike,” and you’re right. But honestly, it’s so much more than that. It’s one badass bike. http://www.quadmagazine.com/quad/features/article/0,24942,1587044,00.html
I need to know what I have and what tire really go on it, Mine has 24x11x10 on the back and 22x8x10 on the front and I need new tire but I don't think are the right size. Also I can't find the model number listed but it looks like a 250 quadrunner 2wd and I think it is a 1987 maybe, can anyone help me, also I it has a rich running sound and I put a carb diap in it and cleaned the carb. is there a jet needing replaced?
I live in Minnesota and bought a 2016 CFORCE 500 HO. I am in hope to see if there is anyone in the US that is experiencing this sudden drop off in RPM below 4000 RPM. I have uploaded some videos of my issue on YouTube. I will list three of the four I posted. The fourth can be found on my channel but it is a comparison between my Polaris 570 and my CFORCE 500.
I quit on my first dealer because we just did not mix well together. I brought it to another CFMOTO dealer that just became a CFMOTO dealer in January 2016. They are in a large ranch and agriculture area in a neighboring state that is pretty close to where I live. They have close to every brand available. They are a much larger dealer than the first one I bought the unit from.
I brought the unit three weeks ago to them and they have worked on it a good solid week and have given up on it. I have read reports from owners in Canada that the dealers there were aware of the issue and have had success in fixing the herky jerky drivability issue.
I am picking it up tomorrow and bringing it back home. It has been to the trails of the Black Hills this year and was new in late April. 300 miles on it. It has never changed. Very hard to ride on the trails or when I herd livestock.
Here are the links to my videos.
I can't accept that this is normal operation. Does anyone from CFMOTO China scan these posts?
I need help that CFMOTO USA has not provided.
