2004 Suzuki LTZ 400 dies when I give it gas.


Recommended Posts

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 have worked about 4 weeks on my Griz600 and have burnt 2 CDIs up ! I added a wire harness and stator and It starts but runs erratically like spark timing is off ! So I would like to try another CDI but I don’t want to Pay an arm n leg ! Anybody have one ? Thanks

      I have been trying to get my Griz600 running right for 3 weeks ! Grandsons used it and it quit running , no spark ! New stator etc and started but ran terrible ! Found a burnt capacitor on cdi . Installed used cdi and burnt it also but ran same as other cdi . Came to conclusion wire harness had short so stripped it and found some bad spots fixed and another cdi ran terrible again ! Bought another harness and same rough running ! Checked spark timing with light (put tdc mark on case and on pull start hub) and when it starts timing right on but will jump 25+° retard ! When timing is on tdc marks it has no power ! The stator is new but I am wondering if the pickup coil is triggering incorrectly ? Also had top end apart when I first started having trouble and although rings were good I installed new rings . Also new timing chain and check the valves , they were good also . It kind of seems to boil down to the last stator I installed new ? I have done trouble shooting on quite a few cars , trucks , dirt bikes and ATVs but this is frustrating me ! Just wondering if anyone has any ideas ? Carb was new last yr and I checked it ! I

      IMG_4272.MOV Originally had my griz600 stop running and then wouldn’t start ! After testing all coils , valve lash , compression (115psi) and all tested ok I bought a used cdi . After cdi install it still wouldn’t start (no spark) ! So even though the stator , pulse/trigger and charge coils check within good range I decided to switch the stator etc ! It started but It is very unresponsive on throttle and acts like it is running in 2 Different spark timing ! With slight throttle it will take off good but instantly go into a very different running mode with no power like timing very retarded but it will switch back to running good for short period then bad again !  Since I replaced the stator and it started I then decided to install the cdi I replaced and it did the same thing ! Also I noticed the Used cdi I Took off had a capacitor that had swelled and extruded from the back of the cdi . I had always heard and I believed that when these CDIs go bad they machine will quit and will not run . Is that true ? I also checked the cam/valve timing and its ok ! Checked with timing light and it does fluctuate on idle ! I am thinking I have 2 bad CDIs . I also switched the trigger Coil wires and would not start then . Man , this thing ran good before and I am confused ! Video below may help !

      Backstory: ATV Ran fine, once stopped in the forest and had to be towed back to my workshop. Found that the stator connector was melted together. Fixed that and it ran mostly fine but intermittently lost spark. Changed CDI box which fixed that problem. Ran fine for a year, but started to misfire more and more often until it did that most of the time. It's not really losing spark, it's firing when it's not supposed to, occasionally making the engine kick in the wrong direction if the revs are low enough. I found that disconnecting the charge regulator would make the problem disappear. I measured the regulator, one diode seemed bad so I got a new one. No change. I then bought another new CDI box and changed the stator and ignition sensor as well as the ignition coil to make sure everything in the ignition circuit was new.

      And now, it's still doing it. I'm leaning to a broken cable/connector somewhere but it seems illogical to me that it would spark when not supposed to if it were that. Any suggestions is very much appreciated!

      Hi i have a honda 350es 2002 4x4 (same as rancher but canadian edition). My problem is the clock and trip meter always resetting when i power off the bike. The trip meter reset to 0.0 and the clock flashing 1:00. The other function work normally gear shift, hourmeter and odometer. If i power off the bike for approx 2-5 seconds the clock and trip meter didnt reset. The battery is ok and all the fuse is ok. Can someone help me with this problem please. I found anything in my service manual.
      thanks

      Anyone know where to locate these, or generics? The generics I seem to find have the mount on the wrong side versus the hose outlet. PITA!
      Also, is the rear master cylinder rebuild kit any good?

      The front wheels of my quad have a ton of slop.  Its the spindle as shown in the picture.  There appears to be an outer plastic bushing of some sort and then an inner metal hollow rod that the attaching bolt goes through.  The slop in between the inner attaching bolt and the hollow rod going through the plastic bushings.  I see kits for bushings for sale, but I have not found just the spindle parts.  The length of the spindle where this bushing goes through is about 80mm.  Does anyone have a source for these parts that you could point me to?
      Thanks.
