My wife's Z was getting a tad hard to start so I figured I'd better check the valves. there was a recent post where the guy stated that he had never done it and did not know how so I figured I'd snap some pictures as I went and maybe help somebody out. Here's the quad-2004 400. It's a great...
Don’t “need” to mod the airbox, but taking the lid off helps as long as you don’t ride in water. The stock carb is the real choke point in airflow. With that said, I’d use a DJ 25 pilot and 160-165 main, needle on 3rd clip, mixture screw 2 turns out to start with.
It runs for about 5 minutes and then shuts off like someone hit the kill switch was starting back up after about 30 seconds not right away but seems to have gotten worse takes about 15-20 min now to restart and sometimes when it does runs awful
That’s an odd one. Try cracking the gas cap just a little loose and running it to be sure it’s venting and not causing a vacuum in the tank. I assume it’s the same with the petcock in “prime” as well as the “on” position.
If that doesn’t help, it could be a CDI wire getting hot. Take a look at the CDI connectors for loose or burned pins. I think I remember seeing something about shorted connectors on the stator that would also act like that.
New stater new coil pack I bought a new Procom CDI unit no difference from the stock to the Procom Also borrowed a big gun cdi from my buddy also no difference I have messed with the gas cap no difference May be a connector problem to the CDI have not ruled that out do you know where I can get wire connector for cdi Maybe I could try that next but as you can see I’m running out of options
It would be part of the harness. I’m guessing you have a short somewhere within the harness or it’s connectors. A continuity check probably won’t find it, but you might find a wire with high resistance being the problem.
So, I just bought a 2006 ltz 400. It has a big gun full exhaust on it. No air box lid and some filter that looks like a k&n but it’s not. Not sure what brand it is but anyway, it appears to have a new stock carb on it. I think it still has the stock jets in it because it bogs when you hit the...
My quad has had problems electric starting recently and it sounds like the engine is just spinning and not engaging. She is able to be bump started but absolutely nothing engages when I try to electric start it. Any information would be helpful.
I bought and 08 z400 with the engine off n disassembled, rear journal on the exhaust cam is scarred, i have repaired it but i dont want it to happen to this engine, wiseco piston,stage 2 hotcams, ported n polished head, kw valves etc. Has anyone found out what causes this to happen in these...
