sitting on the bike, at your left foot, behind that cover is a stator and pick up coil ... sometimes the pick up coil goes bad, or needs to be cleaned off and set a little closer to the stator if you have adjustment.

check for fuses along the way too

most likely it is either the coil, or spark plug cap. i have seen many spark plug caps go bad in the 35 years of repairing small vehicles like this. a quick way to check that (in your case) is to run the engine until it dies, then just remove the cap, and push the wire onto the end of the spark plug. if the machine runs fine, there is the problem. funny thing is, a bad cap will eventually take out a coil. as far as how the machine makes spark, as the engine turns, it rotates a flywheel. inside of the flywheel there are magnets. on the side of the engine under the flywheel, there are a series of coils called a stator. as the flywheel magnets go past the coils, it creates a magnetic field. that creates electricity. that current (the part for the ignition) is sent to a capacitor inside the cdi box. when the trigger coil (more magnet/coil stuff) sends voltage to a different section of the cdi box which sends the voltage created by the stator to the ignition coil at the exact time it needs to be there. there is also a "kill" section in the cdi box which either grounds out the spark, or interrupts (keeps) it from reaching the ignition coil. trigger coil voltage is usually in the 1-2 volt range (ac), the ignition voltage from the cdi box (same as from the stator) is normally in the 100 volts range (ac). the ignition coil is simply a step up transformer, bumping the 100 or so volts to around 15,000 volts. the spark plug cap has a resistor in it, so it minimizes the amount of radio frequency emitted by the ignition. that for most of us means nothing. but if you happen by a work site using high explosives, means life or death! that radio frequency emission can set off a blasting cap, and thus as much explosive as the crew is using.

      Hi everyone! I have a 1986 yamaha moto4 200 that's been sitting for a while! Cleaned the carb, replaced engine oil, put fresh gas in it. Got it running and went for a ride! It was running great just a little backfire once in a while! I barely made it home on the way back and now the bike won't run at all since then! It will start if I give a little bit of throttle but dies instantly as soon as I let go off the throttle! And even if I try to rev it up it'll sound like its not getting enough gas.. it revs up a couple hundred rpm's and backfires through the carb.. it almost sounds as if I was trying to take off from zero in 5th gear! Nothing is seized though! I dissasembled the head and the piston and cylinder are fine! Rebuilt the carb, replaced the ignition source coil.. I don't know what to do anymore.. compression test shows 90 psi Specs are 128 psi but i'm not sure if I trust my compression tester.. any ideas? Thanks!!

      Long story short. I bought this off my neighbor and only has 3 gears. The part that holds the shifter rod on broke, this is on the inside where the clutch is. The rod moved out of its spot and when they welded it back together only has 3 gears. I have a new case for it just need to know how to get the shifter in the right spot before I put it back together. I am missing the indicator that shows me where neutral is. A link to a good Manuel would be great. Thanks

      I recently purchased a 2005 Suzuki LTZ 400, for the first few days it ran like a champ but now when it gets hot, no matter what you do, it will stall out when you stop. Even going from 2nd or 3rd gear it still stalls out. It still runs perfect, it just stalls when I hit the breaks (hard or soft). I don't know much about quads so I could use some help.

      Looking for the rectifier.  Most bikes have near magneto.  It appears the KQ has it in front.
      Can someone tell me exactly where it is? 
      Bike not charging and magneto checks out ok

      I have a 2001 Quadmaster. Bought it from the original Owner. Its in Excellent condition for a 2001. The guy said there was a carb problem when I bought it. It seems like it is not getting fuel. I took off the tank, cleaned it, replaced the gas with fresh Gas, Installed a New Gas Valve. Then rebuilt the carb with a Carb Kit. Started it up and same damn thing, seems like its starving for gas. It will also backfire out the exhaust while trying to accelerate. Now the weird part. I started it the other day and it ran great. We went for a ride and it ran as if nothing was wrong with it. Started it the next day and back to running crappy again. I was like WTF !!! ... Anyone have any ideas of what the problem could be?

      Hello ladies and gents. Just picked this guy up in October and getting around to doing the required maintenance to make sure everything is right before any long rides or work is done. 
      Some background: I am I believe the 4th owner, (however the 3rd didn't actually ride it). It has unknown hours or odometer due to what appears to be a common issue. 
      I have noticed the fuel gauge doesn't work (just keeps flashing empty),
      I did come across a google search that mentioned these were a common problem but was fixed by replacing the dash (seems like overkill) and another post mentioning someone attempting a fix. 
      Any particular issues on these quads to pay attention to beyond the dash ?
      Going to be replacing the rear tires, oil change, filters and plug. Anything else I should do with an unknown history such as diff flush/change ? 
      I believe there is a service manual here but I need a few more posts. Hopefully this post will drive some answers and more questions I might have. Thanks!
