Hey guys, figure you guys would have some helpful direction or answers.
So, 05 Sportsman 700 carb, new carb, fuel pump, new plugs, new air filter, new everything I can think of that is usually the running issues. Starts up fine, seems to run fine, but if under load, two people, or even one person, up a hill, or pulling a drag chain for the driveway, it starts to cut out and sputters and loses all power, until I back off on the throttle and just barely try to let itself catch itself and then I can take off again.
I am going crazy trying to figure this thing out. Other than that, the quad runs great. Parents bought bran new, just used around the property, 5000 miles on it. Any ideas???
I finally found an awsome app for your phone that shows you on a map all the trails near your location. You can read or add reviews, look at picts...etc
Its called: atv escape
By Dra O
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 rebuilt the carb on a 1989 350 Big Bear. This is a Gen 1 carb ( 2 cables running to throttle).
Quad starts and runs but I have fuel leaking from the air intake.
Is the float set to high / low?
Does the needle for the main jet need adjusting? I have it on the center groove ( 2 groves above and 2 groves below).
All jets are new, float and needle and seat are new.
Thanks for your help

Hello. I am a new member as of today. I had a quick question to ask. I recently was driving mt HONDA RANCHER 2004 GPSscape 400 and my display stopped working. I was driving the atv and all of a sudden the speedometer and the service lights went out. Also the lights stopped working. I am still able to shift gears, change from 2wd to 4wd, and can still select if I want EPS or Auto. I have checked my fuse box and have changed a few of them around. It did not change anything. I was wondering if anyone had any idea of what had happend. Thank you for your time- Trenton
So i was riding the other day and my quad randomly shut off. It started back up and ran completely fine for a little while and then it started idling terribly.
I cleaned the carb and changed all the jets and everything except the float due to the rebuild kit not coming with one and it actually runs worse then it did before.
It will run and idle decent now but when I give it gas it dies.
Does anybody know what could be wrong?
I also changed the spark plug and air filter along with the oil and oil filter.
I went out to ride my quad today. When I started it up it ran for a minute, then died. Since then it will turn over but won't start. I've check the spark plug and get great fire. I have had this quad for about 6 months, and very new to breaking it down. But need help. Thanks
I just bought a Used Kodiak, that I will be using mainly for Ice fishing, and it ran fine at the guys house started right up and everything seemed fine.
I Got home and Hopped on to take it off the trailer, i Pressed the brake and hit the button and it turned over, fired up and then dies. (it starts cold so I was not concerned.)
When I hit the electric start again there was no noise or anything, Just the coolant indicator light illuminates when ever I hit the button. I cycled through the shifter (park, reverse neutral, and drive,.) and then hit the button again, with the same result.
I noticed the park light does not illuminate, but the reverse and Neutral do.
I tried starting it in Neutral, and again nothing it just illuminates the coolant light.
SO am I doing something wrong?
I finally put it in neutral and pushed it off the trailer, and started googling. I have not seen anything on this being a problem or even what it would indicate. Any help appreciated.
