Linhai 260cc ATV No Spark

Recommended Posts

Hello everyone. I am new to the forum and am hoping someone out there can help me with a no spark issue I am having with my ATV. I have the service manual and I have replaced/checked everything that I know how with the exception of the Digital Igniter Unit. Does anyone know how to test this item to verify if it is bad or not. Thanks in advance for your help. Stacey

OK, so I replaced the CDI, still no good. So, I have replaced the coil and CDI, verified my Kill switch works correctly, verified no grounds and good continuity in all of the wires. I verified I had the correct ohm readings (according to my service manual) for the pickup coil (Trigger) but have done nothing else with it. I do have a question. I have 12Vdc going to one of the contacts on the ignition coil, as it should according to my service manual. The coil is only suppose to have 3.6-4.8 ohms between the contacts so I assume I will see the 12Vdc on the other contact when connected (which I do). However, while sitting in a static condition, just for the heck of it, I checked the voltage on the spark plug cap, and I have 12vdc sitting on it, and therefore sitting on the spark plug while it is on it. Is that normal. That wire is coming off of the secondary coil and I had thought that voltage must be flowing through the primary coil in order for it to induce voltage on the secondary coil. I know a little bit about how coils work, but have no idea if that is the way that they are suppose to work on ATV's. Again, just for the heck of it, I check the voltage while trying to turn it over, and the 12vdc that was on it before just trickles down to zero. Any ideas on what to do? Any help would be greatly appreciated. thanks Stacey

      Hi all,
      I recently acquired an old Bayou from a neighbor that I cleaned up a got running, then from nowhere a problem crops up where it refuses to start........ I pull the plug and it has no spark, pulled the plug cap off and laid the bare wire on the exhaust header and still nothing......once in a while though when I push the starter button but as I let off the button it might spark once. Now it did begin sparking normally just once and I plugged everything back in and it ran normally again until I turned the engine off. Next time I tried starting it we were back to no spark or the one spark deal.
      I have tested the stator wires at 140 ohm, the pick up at 130 ohm (I can't seem to find a reliable number for these values online), I bought a new ignition coil and ignition switch on chance those may have been the problem but were not, not sure where to look from here......... does the starter relay switch have anything to do with the ignition on these? I know these older Bayou's are magneto type ignitions and do not need battery power to operate but I wonder if there are safety switches involved I may not be aware of. Also, can someone point me to a good wiring schematic for the magneto 220's? Pre 95 I believe.
      thanks for any help!

      I have a 1998 Big bear 350...the tail pipe/spark arrestor is broke in the exhaust....how can I get it out to replace it? And what's the best way to get the new one in?

      Bought a 2019 king quad 500 AXi few weeks ago.  What are peoples feelings on the break in time and fees a dealer charges.  Not sure if i should do the break in service myself. Thanks

      Fixing for a friend. Atv was at a different friends house to be fixed and he rebuilt the carb and had it running nice, then it shut off and no more. He replaced the key and the coil.
       
      So he got busy, so I am helping, I checked the wiring from the stator to the cdi, and from the cdi to the coil. All is good. I checked resistance on the pickup coil, good, and on the source coil, open. I buy a new stator (China) and the 4 prong plug only has 3 wires in it while mine has all 4. I checked resistance in the source coil and it's in the 300's. I pulled one of the old pickup wires out of the old stator and wire it in the new one. Still no spark.
       
      Why do the wires differ, I checked the VIN again and it's "J" for the year and I got a 1988 stator. Please help!

      So my parents have not let me get my license yet and I need to get around to gets parts and stuff.  Answer: Yamaha CW50 scooter.  This is a 2-cycle self-mixing scooter that so far, I am really surprised with the power output and speed.  It reaches about 45mph since the speedo has been disconnected and has plenty of power for two riders.  Its stupid looking, but with some work and a title and plate, it'll take me around town..  My issue is this:  No key.  I bought it for $150 from a friend and he bought it from someone for $100 who wired in a switch in place of the ignition.  That guy got it form his neighbor who's renter left it behind.  The scooter will run with this switch on or off (kill switch on handlebar kills engine)  To get it tiled and a plate so its road worthy, I need to get the ignition working either by a replacement key or a new ignition.  All wires are cut to the ignition and the switch turned on the power to the signal light switch.  Also, the 2-cycle oil was leaking out the carb, through the air filter and onto the scooter.  also, it runs great, but its making blue smoke with throttle and the muffler is wet with oil.

      (I have new signal lights for it btw)  So the issues I have with it summed up:
      No key (need new ignition) smokes burnt out headlight-  can I replace them with LEDs?

      I have a Chinese Hybird 250 or that's what I was told it was. I found 17 numbers on the frame. Will these numbers tell me exactly what it is that I have? (I know that its a 2006 from a plate on the front)

      Ok, so got this thing, assembled, and even added acid/assembled the battery with a solid trickle charge and the battery is fine.
      As far as I can tell, I have checked all the fuses I can find, but I have ZERO power to anything. Even the console will not light up when turned to ON.
      Is there some sort of hidden parental/child disconnect or safety switch that I'm not aware of? ANY help would be appreciated.

      Somehow I lost all of my spark on my 350Big Bear, its a 1990. It ran well for maybe 3 days! Thought it was the carb. Cleaned it 4 times. It was losing power at midrange. Got worse and worse. Finally nothing!
      Are these good coils? I was thinking I could swap?
      2002 Honda-200cc: primary 0.4(ohm-200) secondary 9.0(ohm20k)
      1990 Yamaha-350cc: primary 0.8 secondary 11.0
