Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!

I own a 2007 Polaris Sportsman EFI X2 model and have for the past months been experiencing loads of issues. Basically the Sportsman will only start if the throttle lever is pushed and will not remain on idle. This situation has persisted for months now and I have replaced the following parts:
Sparking Plug
Fuel Injector
Fuel Pump
Fuel Filter
Fuel Valve
Fuel lines
Power Control Module
The last part replaced was the Power Control Module and the Sportsman was tested and worked fine on a couple of occasions which were days apart so much so that some weeks later I took the Sportsman for an extensive ride and it worked perfectly. This was three weeks ago and today I tried to start the ATV it worked fine a few minutes and decided to switch it off so that I could continue with some prep work. A few minutes later tried to start it up again but noticed that it would only start if the throttle lever was pushed and once I removed my finger from the throttle lever the engine would not stay in idle and would simply shut down. Several attempts were made to start this and also tried to re-adjust the setting by turning the built in wheel like mechanism in the throttle cable but it was to no avail.
The above have been repeating itself on an off basis. Each time a part is replaced the ATV would work and then all of a sudden will not keep its idle. At this stage I cannot think of any other solution other than possibly some sensors which might have an intermitting fault but I cannot really say.
Would greatly appreciate any assistance.
Thanks in advance.

I get it, turn counterclockwise will decrease, turn clockwise will increase. My question is what exactly am i increasing or decreasing? Is it clutch pressure? In many videos i've seen it's always "turn counterclockwise" until you feel resistance then back off. Why is it always to decrease?
I'm just curious as to what exactly is going on when i turn that screw right or left. And, since there's no manual clutch to engage or disengage, what is going on inside?
Reason why i'm asking is while going down a hill in 1st gear, it appears to pops out of gear, but no neutral light, and if i stop, it's in 1st gear still. BUT, (always a but) if the engine is warmed up, it stays in 1st gear. The hill is too steep to use any other gear, so 1st with the brakes is the only way to go down.

Hey guys I have a 99 xpress 300 and I'm having an issue, I rebuilt the engine and it will only start when I put my han over the intake on the car (when I manually choke it), I am not very familiar with plunger chokes.could some one help me understand how this choke is supposed to work and maybe how to ajust it so it works, thanks!

I believe the Kawasaki is either an '03 or '04. Green automatic with shifter on the right side. Rear differential was bad, so I replaced it with another. The 4 wheeler rolled in neutral when I parked it in the shop to work on. Took old diff off and replaced it with another one. The diff I put on, turned before I put it on the bike. Once I put it on the bike, the rear end wouldn't move at all. It's like it's stuck in gear. Bike is still in neutral. I've tried rocking the bike while trying to put it in high, won't budge. Can anyone tell me of something to check or try? I haven't opened up the transmission case yet to see what's going on. What should I be looking for?
