My Girlfriend rolled her 2 week old 2011 Raptor 350 coming back from Spooner pass in Lake Tahoe. It rolled with her twice then flipped over a log and landed upside down about 25 yards downhill on rougly 60% grade. It took 2 hours and the help of other riders who stopped to help. On the way home it started to cut out. I discovered it would run with the petcock in the "Res" position. Then it stopped running altogether. I discovered the air intake box full of oil. Cleaned that up, sprayed a little starter fluid in, it tried to start but, wouldn't. Drained execess fuel from carb. sat for a day. Charged battery then fired right up. Spittin and cracklin and back firing. Then smoothed out until I put petcock into "On" position. I haven't owned a bike since the 80's. So learning all over again. Anyone have a suggestion for a fix or what to look for.

p.s. Girlfriend ok. More damage to pride than self. Thank God! Could have turned out really bad.

Check the vaccum line going to the petcock for blockages. The line and /or petcock might have gotten oil in them too. That's where I'd start looking first. Does the petcock look like it might have gotten damaged?

      1999 Yamaha Big Bear 350 4x4 no spark

      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!

      Need help! 1987 Yamaha Moto 4 350
      By P_syko
      I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!

      2008 kazuma 800 4x4. i need wiring help. no spark
      By carkivey3
      i just picked this up. was told ran fine but overheating issues led to replacing head gasket and head. has not ran since. he is not a mechanic but helped someone else who he could not get back to finish job, got aggravated and put up for sale. i was thinking timing issues. i have 110-120psi on all 3 cylinders so i think valves are correct. dont know about distributor yet. however i have no spark. i have no power going to ignition coil. tried to follow white wire but gets lost in wire harness. does anyone have a wiring diagram? can anyone tell me what conditions have to be met before starting. motor turns over so i would think all safeties are met but you never know.

      Moto 4 350 low oil
      By P_syko
      Does the 1987 moto 4 350 have a low oil sensor that kills spark? Or are these too old for that kind of thing?
