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.

      recently picked up some project bikes off CL for cheap.  got a honda fourtrax (the ancient 4x4 kind with the straight axle in the front as well as the rear and a back-up kick-start)  plastics are crap, but my goal is to get running like a champ and patch the plastics up and sell to one of my many friends that want a reliable 4x4 for dirt cheap and doesnt care what it looks like.
      so the former owner says it needs carb rebuilt, but its sat for 3+ years since so who knows.  things I see:  carb is missing (he gave me a box of parts along with the bike), engine turns over and feels good with kick-start, brakes need work, battery missing (That always puts me off, cause then I know most likely someone's been tampering with the electrical.
