Starting this build thread to keep up with everything on my build and hope to motivate someone!
I picked up this 2008 Yamaha Big Bear 250 2 weeks ago. A guy that I hunt with parked it at the hunt club for a year or so before I asked him if he wanted to sell. He said " fill my feeder and throw some batteries in my cameras, and you can have it". Sounds like a deal to me!
I have attached some pictures of how it sat under a tarp in the woods and when I got it home and cleaned up a little.

So my moto 4 is smoking white smoke and when I go to first gear and get about half throttle there’s no power and it sounds like it’s bogging

I been working on this thing for like 2 months now and it will not run right, is very smokey, and has a pretty loud tap that i think is in the bottom end. Not sure how much the parts are but i will put the time into it if they are pretty cheap. Im not very experienced but going off how the plug looks and the oil on top of the piston i am getting a whole lot of oil coming in from somewhere, not sure if it can come from the valves or if the rings are just shot, my cheap scope cant really see the walls of the cylinder too well.

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!

Hopefully someone can help me out, I purchased a 350 moto4 2wd while I'm trying to fix a dying honda. I can't see the vin number as there was damage and a bar has been welded where I think the vin should be, The decals say 350 moto4 Huntaway, it has the square gear change low, high, reverse up on the left of the handlebars and it has three rectangle lights up on the dash. after googling I'm struggling to find anything called huntaway, Any ideas? Thanks.
