I would check for a short somewhere, either in the switches and wiring, or an electrical part that may be shorting out. Maybe the fuel pump or injector. I think I read somewhere that there was a recall on KQ 450 & 700 ignition switches, you may want to look into that too. Does your battery stay charged?

okay i am really happy now a few days ago my friend and i found the problem we were going to go back to square one and go through the whole entire bike and check everything looking for bad connections, corrosion, and broken wires things like that. one of our friends at the local shop let us borrow a service manual. i know this is going to sound dumb but to make a long story short the first thing we decided to check was the tip over sensor/ fuel cut off. well i looked at it and it has an arrow on it and i noticed it was pointing down. the four wheeler runs great now. i was un aware that my friend messed with the sensor from the start so i did not know that it could have been the problem.

That's great, I'm happy for you. It's an awesome feeling when it's something as simple as that!

lol na i cant return the ecu unfortunatly but im just going to use the ecu as a spare im using the new on on the four wheeler now. yes it would have been nice to know the sensor was upside down before i got the ecu lol. but im just happy it runs now it sucks to buy something and keep having to put money into it and you cant even use it.

i like the four wheeler over all very nice styling and yes it has independent rear suspension. it rides really nice. i think the four wheeler is a little underpowered in the low end area. but i see people doing wheelies on them all of the time on youtube on mine that is not near possible. i do have 27 inch tires 2 inches larger than stock so im sure that has a little to do with loss of low end. i might get a power comander for it some day and a uni filter just because i heard the stock air filters are crap. I actually havn't rode any since it has been fixed i want to get out at a mud fest event but i work this weekend and they are having one at redneck yacht club in florida. i need to work on the snorkel a little more too i had to go through the whole thing because come to find out the guy who sold it to me put the snorkel together without glueing most of the piping and rigging some of it so im fixing it now.

th e fi light will always go on when the engine is not running or stall

with that kind of mileage and with a snorkel kit i would consider the condition of the motor

if you found debri in your intake then shouldn't it have gotten in to your motor

fuel injection is very simple if you under stand it

check compression and leak down readings

check valve adjust ment

also check if choke valve system is siezed/stuck

      2023 Hisun Axis 700 fuel problem
      By ButchM
      Hisun 700 EFI. Replaced TMAP sensor had broken off . Fuel pump pressure 41psi. The only way I can keep it running (and runs fine) is to close off fuel return line.

      2003 Kawasaki bayou 250 carb problem
      By dkgg5755
      This thing came with a cheap aftermarket carb on it the problem I'm having is it won't start with choke installed into carburetor it will start and get run without it installed then bogs out after about 2 min run time I've checked timing , compression, checked valves for proper clearance , also did a smoke test for air leaks found none.

      My first trailer project.
      By Frank Angerano
      So I decided to pick up a small trailer if I could get one for the right price.  I found this one for a few hundred bucks on Craig’s list.  It is  a galvanized trailer which is exactly what I was looking for. The wood was shot and needed some minor repairs which I could care less about as long as the chassis was good. 
      I striped it down and put a new deck on. I had some vinyl realtree graphics that I had laying around so I added them to the fenders which I think worked out well. Very happy with this little guy.  
      I'm having the iron workers at my jobmake me up a few lightweight side rails that will have a 22 degree bend in them to accommodate the tires that slightly hang over the edge and will incorporate some tie down points as well.

      Suzuki king quad 300 idles great but Boggs when you apply throttle
      By 97kingquad
      Okay so I bought this 1997 sazuki king quad from a guy and he had it for a few years. 
      He had it registered and on the trails last year but he said it bogged and backfired when he would try to drive it. so it sat for a year. 
      I bought it for 800 bucks and got it running that night and it ran great for a few days 
      But I parked it the other night and went to start it again and it was really hard to fire up and when I did it was bogging and idling high then low again.
      So I took the carb out and cleaned it (ended up doing it twice because it was still doing the same thing) 
      Now today I have it running slightly better, but it is still like 20% 
      I have been looking it up and trying to figure it out but I can't find the issue, has anyone else had this problem? I'll attach a video of it running and giving some throttle
