2003 Suzuki Ltz400 stalling problem

Recommended Posts

So my 03 LTZ 400 isnt running rite. Starts fine idles fine, but as soon as you shake it a little bit it shuts rite off. If you break hard it shuts rite off. And unless you give it constaint gas while in gear it will just keep stalling, even down hill in the trails.

ANY IDEAS!!!??????

it sounds like the carbi is dirty or has some water in it.

but also could be a broken wire that is getting moved while shacking or braking.

what have you found so far?

      It will go into neutral, 1st, 2nd, and reverse but nothing after 2nd gear. The shifter moves freely going up completely nothing but when you shift down it works. I’m not sure if it’s tranny issue worth messing with or if I should just buy a new one.  Overall besides that the thing runs like new.

      I have a 99 Kodiak 400 4X4 that I picked up for $300.  The previous owner had modified the foot shifter by welding a piece of rebar to it so he could hand shift while plowing.  As you can imagine, the allows for much more torque on the shifter than it was designed to have, and he broke the stopper off of the the shift mechanism.  No big deal, I ordered the part and put it back together, went through the carburetor and off we go, it runs pretty good.  
      The first thing I noticed is that when I put the shifter all the way down it goes into reverse, I'm supposed to twist a knob to get it to reverse but this seems to be disabled.  Also, once in reverse, it's a bugger to get back out.  I have to hold the shifter up, then quickly back down and up again to get it to come out.  All forward gears work fine, clutch is tight, no problems.
      The reverse cable and lever are in tact and seem to move freely.  
      My question is this:  What does one normally have to do to get this thing into reverse?  I assume put it in neutral, twist the knob, kick the shifter down.  Does the brake need to be applied?  I'm not sure what's going on here, I suspect it's been 'modified' as it goes into reverse without the proper precautions, just not sure if the mods were external on internal.
       
      thanks

      When it is  cold outside, say 35 deg F and colder, it is very difficult to shift to Reverse from neutral.  Engine temp doesn't have an effect.  I apply the brakes hard with the hand lever and the foot pedal.  In another post I read that high idle can affect shifting when the engine temp is warm. 
      I will try it with lower idle speed once I find the screw.  In the interim, can you tell me if there is some sort of adjustment for the shifter?
      Thank you

      Hello,
      I recently picked up an ‘07 KFX 700. All was going well, rode it about 40 miles, when it started bogging at low speeds. If I kept the revs higher, I was just fine. Also, a persistent issue since I picked it up is the fairly difficult start (but it is abnormally cold right now and the quad is jetted for the dunes at summertime).
      Regarding the complete lack of idle, I have to rev it a couple times to get it to idle after starting it, after which it’s 50/50 whether it remains idling. I don’t have low fuel, but all of this began after I rode it pretty hard and the radiator fan kicked in. Might be overheating, just wanted to hear your opinions.

      When i try to pull start (push start/roll start) it made a not normal sound  and wouldnt stay running.
      If my bottom end is blow why would it still turn over fine,
