    I’ve read some threads for no spark issues but I haven’t seen everything addressed yet. So I got no spark and have checked a ton of stuff…here is a quick list. 1. Coil and wires - check fine 2. Pulse Generator - don’t have peak voltage tester but it is throwing off a signal about .2 to .3 volts...

    I recently acquired a free 1999 honda foreman 450es from my father. Since I got it I've put in an new battery, new wiring harness, new tires, and rebuilt the brake system. After that I noticed a large battery drain and tracked it to the fan control unit which I replaced. After that it ran fine...

    I need some helpppp!! I'm trying to bypass the reverse inhibitor on my 300ex because I think it's stopping power from going to my coil. I could be wrong . I have 12v to the reverse switch wire but not to the neutral. I was in neutral so if I was reading it right I believe my neutral wire...

    Hello, I’ve got a 2004 Honda Rincon 650, my family was recently using it to pull logs when it died (might have died multiple time, I’m not sure wasn’t there) but eventually it died and no longer cranked at all. I jumped the starter and it crank perfectly but still didn’t start. I pulled the...

    My 300ex would lose spark and regain spark just to lose it again permanantly. It cranks over but doesnt start. I have replaced the cdi box, voltage regulator, stator, pickup coil, and from what i tested i believe the ignition coil through the spark plug cap is good. There is 12 volts getting to...

    I have a 2002 Honda Rubicon Foreman that my stepfather has neglected for the past 15 years. It has been in his garage collecting dust. My goal is to awaken the beast. It only has 100 hours on it and pretty much in prime condition. I have done the following: -Replaced the battery -Changed the...

    I've seen some discussion around this issue. The engine starts only when the start button is released. Short version - the neutral sensor was bad. The high resistance of the neutral sensor raised the ground potential to 2.5V when the start button was pushed. The ICM only fired when the...

    Hello All, I am trying to figure out a spark issue on my fathers 450 s. The only time it will spark is when you first press the start button, and then a second time when you release the start button. Any thoughts? I have not had a chance to do any checking with my meter just thought i would...

    Picked up a 300ex. No spark, but turns over. I grounded out both the reverse switch and the neutral switch at harness near battery. Engine starts, but doesn’t rev up. Seems to be limited, like it’s in reverse Limited mode. if I unground (open) the reverse switch off, it doesn’t turn over. Same...

    Hello All, I picked up an 1986 TRX125 a couple months ago and I'm finally getting around to fix it up. When I bought it the guy said it could not be in neutral to start, and that it had bad compression. I have already fixed the low compression, but I'm trying to figure out why i cant get spark...

    Just recently bought a 2008 Honda Rancher 420 4x4 for my stepbrother for $1000. It supposedly has a fresh top end rebuild. It was running great up until the other night, not even 30 minutes into riding it, after we got to the mudpark. My stepbrother hit a hard bump, and it died. I noticed that...
  15. Honda FourTrax
    I get a good spark occasionally. I've replaced the coil, but the old one was working fine a week ago. The pulse generator and alternator tested fine on the resistance checks. Could it be the CDI? Or do I need to open the left side and check the pulse generator?

    Just joined this forum. Thanks in advance for any knowledge shared. I am reviving the foreman mentioned above. After a few days of work, I took a few victory laps around the house. Parked it in the driveway. Went to put it in the garage, but the fuel pump will not activate when key is turned and...

    So recently I purchased a pretty rough 200SX used. Me and my buddy have been working on it for a couple weeks now, the original carburetor was missing a bunch of parts, so I installed a close replacement. For the time we set up a container with a fuel line installed into it for a gas tank...

    Hi all! well as the title implies, I'm having a pretty rough time. I got a 2000 honda fourtrax 300. I ended up rolling in on a mountainous trail a little while back and had to be searched and rescued out. During the roll, the ignition cylinder got busted out into pieces, brake throttles...
