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!

My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area.
Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.

Im aware that this relay needs a positive (+) and a negative (-) to activate the other side. The blue wire is the neutral wire so when in neutral it gets ground. The green wire is from the parking break; when you pull the break in it gets ground (-). however one of those two needs to be neutral so that the positive from kill switch can go to the starter relay. The ground from the starter relay is from the start switch. Which one (neutral or parking break) should have a positive (+) voltage?

I am having an issue with a hs500. I bought it broken and have been trying to get it running. It seems to be starving for fuel. If I put my hand over the intake it will crank but will not run for very long because I'm not able to get the correct airflow with my hand. The things I have done so far are. Replaced the fuel pump, fuel filter, mass airflow sensor, idle air adjuster, fuel injector, cleaned the throttle body, replaced the ecu, and still the same issue. I notice the injector does not spray when removed from the head. I dont know if that is common.
I am out of ideas on what to do next. I have removed the fuel line from the injector and it is getting plenty of fuel. If anyone has an idea on what could possibly be the issue I would be happy to try anything at this point.

Well while I was waiting for new parts for the choke, I decided to adjust the clutch. When I removed the lock nut, I found the guy I bought it from or someone else had stripped the threads on the adjustment rod. I couldn’t get the adjustment rod to turn without putting a pair of channel locks on the screw driver, this was telling me something was wrong. So now the rod pushes in and out and spins freely too freely. So guess I’ll have to take the clutch housing off to see what’s going on and replace the adjustment rod, it’s threads are beyond repair, and there is something going on with the adjustment rod. If there’s another way please let me know. The further I go the worse it gets. Thanks for any help.
