2004 KFX 700 Fuel Pump Problem

Recommended Posts

Hello...first post.

Have a problem I have not been able to figure out.  

While back the fuel pump went out...replaced it.  I got maybe 30 minutes..maybe less before the new one went out.

Replaced it again...same thing. Now I am sitting with two more new fuel pumps in reserve but do not want to experiment and blow out another until I have a clue of what could be wrong.

Have checked electrical...seems to be fine but I am no expert. Also the fuse is just fine.

My guess is the regulator or stator is putting out an over current condition and possibly burning the fuel pump out. Have you checked the voltage on the pump while the bike is running?

I have been trying to find something that would even tell me what voltage is wanted...with no luck.

But I will install another pump and see what readings I get.

It’s should not be more then 12 to 13 v at best.   Maybe 14 but I would think that’s about it.

      Several months ago, I finally got around to fixing the bayou. Rebuilt the carb, replaced the fuel selector switch, hoses and fuel filter, and she ran great. Only had 2 minor issues since then where, at higher speeds, it acted like it was choking out when I let off the throttle.
      Lately I've noticed if I let it go for more than a week, it almost drains the battery dead trying to start. I initially thought battery, but after inspecting I found very little if not any fuel flow through the line until it starts and runs.
      I'm a little baffled and don't have much time to mess with it as most my free time right now is spent on getting my rv up and ready for hunting season in the next 3 weeks. So any help on quick diagnosis checks would be helpful. Otherwise I'll just keep starting it every 3-4 days to keep things primed until I'm done hunting.
       
      Oh, and another question on a different topic. Does anybody know what the mounting brackets on the front rack are for? I'm referring to the 2 angled metal tabs with threaded holes that are located on the left, near your knee when sitting on the quad?

      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

      Went shopping on Saturday, picked up another Kawasaki Bayou 220 and a Yamaha Timber Wolf 250
      I really should sell some of these but they are a lot of fun to find, fix and ride
      Of course neither of them run but that's part of the fun!  Az

      When it comes to adding more power to your ATV, the first thing that usually comes to mind is bolting on a slip-on exhaust. However, that usually means you are also bolting on a lot more noise. HMF do...

      Just picked an '03 Bayou 300 2WD.  It runs ok, needs a little help though. Maybe someone can answer some questions for me.
      1. The choke "off" position is the lever all the way right, correct?
      2. The choke seems mechanically... funky. It has a little valve clamp around the rubber boot where it goes into the carb, seems kind of janky, I don't think there's typically a valve clamp on that part? The engine seems like its running really rich, smoking a bit, so I wonder if I can just completely remove the choke cable to see if that's part of the issue? But I don't fully understand the choke needle setup. Is "choked" when the needle is being pushed in, or pulled out? Like it I chopped the cable just outside the rubber boot by the carb, would I be permanently choking it or permanently unchoking it.
      3. I've read that I can tweak the air/fuel screw and maybe fix the rich mix. Where is that even located, and if it's behind a cap that I have to drill out... where is that?
      Thanks for any tips
