I'd check the timing before going too deep into the motor.  Sounds like the chain flopped and jumped a tooth or woodruff key sheared on the crank.  Backfiring  is usually caused by either firing at the wrong time or intake valve not closing completely.

It's a 2 stroke  so it wouldn't  have a timing  chain

Never had a 2 stroke.  I've had a 125, 185, have a 250 quadrunner in the garage now, king quad in the past, about everything Honda made in an ATC, some Kawi's, a Can Am now. Just no 2 strokes.  Thought about buying one recently just because I have no experience with them at all.

      Well the Way I Ride, some of you knew it was Inevitable.
      Below are Three Videos.
      First one is Slow Motion of How it Happens.
      Second one is Normal Speed, and what happens after the Accident.
      Third one Follows more of what happens after .

      I Was Riding By Myself. I was going through a Mud HOLE Either there was a log or a rock, or A Dip but just as I was almost through it, Machine, Rolled over on my right side, as soon as I contacted the ground, I Heard A SNAP! I got up, flipped the Quad back over. I had the wind knocked out of me.

      Kodiac no start project
      By Tinkeringreg
      Hi my name is Greg and I just acquired a free 2000 yamaha kodiac 400 4x4 with the ultramatic transmission that does not run. I plan to get it going and use it around my property

      By Kaz
      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!
