I have a 1993 Bayou 400 4x4 and I have no spark. I tried 2 new plugs and nothing still.

I have checked the CDI black wires to body of the box for continuity and none.

It turns over but no spark, not sure where to go from there.

Any advise on what and how to check other components would be awesome.

Thanks: Garry

I checked everything you could check and everything checked out so I replaced my CDI and still nothing. After a week of going over the atv I looked at the plugins on the old and new CDI. They were exactly the same except the pin placement in the connector from the pickup coil was slightly different so the connectors fit together perfectly but the pins were not making contact. I hooked up jumpers from connector to connector and had spark.  Swopped out connector ends and bike runs perfect. MAKE SURE YOUR PICKUP COIL CONNECTORS MATE UP!

      1st problem, Does anyone know where I can find a stock carb for my Timberwolf, I have tried two different aftermarket carbs and they both suck. The machine runs great until it gets good and warm, then it keeps stalling unless I feather the throttle. it will even stall while I'm trying to go from 1st to reverse or vise versa. I took it to a buddy of mine who is a bike mechanic for years, and he told me try to find a factory carb. When I look online from dealers it says "NOT AVAILABLE" anyone have any suggestions ?
       
      2nd, The small tab on the rear axle for towing is to short for even pulling my small yard trailer, I can't even turn a little bit and hit hits. I tried making an extension which worked great as far as length, but it bends the tab and then the extension drags the ground. I have an idea of what to do to fix it, but wanted to see if anyone else has had this problem and see how you solved it.

      As the 2025 ATV Motocross National Championship Series (ATVMX), an AMA National Championship, got underway with back-to-back Florida AMA Pro only events, it was evident that Phoenix Racing Yamaha’s Joel Hetrick picked up where he left off last season.View the full article

      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 have a 2002 Kawasaki Prairie KVF 400 and im trying to figure out the actual float height... i have read 17mm +- 2mm, seen 13mm and 23mm... what is happening is it will start right up, rev a little and all is fine, when it warms and you put a load on it bogs down and sputters. no i don't have a manual
