Hello Folks....new to the forum.  I have two Warriors (87 and 92), and an 89 Big Bear.  Looking for some help with engine issues on the warrior, and my 89 Big bear backfired and died. Got spark, got gas, seems to have compression, (but haven't tested it yet...next). She rolls over good, maybe too good...seems soft. Have spark and enough compression to blow gas mist out the plug hole when cranking. Suggestions, Been running great since we got it.

You need to get the compression reading and go from there. It could be a valve stuck open a bit and not closing all the way or something worse (hope not).  You say it rolls over good so I assume you mean it cranks fast which sounds like low compression for what ever reason.

      2000 Yamaha big bear 400 won’t start
      By Mister907
      Hi guys, I have a 2004 big bear 400. Last winter while plowing the driveway, I heard a loud pop from the left side of the engine. It continued to run as I looked for leaky fluid, but then died shortly after backing it up and won’t start now. The oil light comes on when I try to start it, no noise or anything else. 
      No blown fuses that I can find.

      2007 Yamaha Big Bear IRS Short
      By jeffinotown
      Hey guys and gals. I've been working on my friends 2007 big bear IRS. Unfortunately after 3 different people got their hands on it and only made things worse every time.  After months of finding just crazy problems everywhere. I'm finally at the point we're its almost 100% !!! But I'm getting a short somewhere between the 4xW switch I believe. I managed to by searching the internet like a  fiend, got my hands on an official Yamaha wire harness for the year and make. But I don't have the numbered component list and to be honest. After hours of going through and making everything so it's  easy to reference. If anyone has a picture of the referenced components. I would be forever in your debt. I've spent hours marking up the blown up diagram so it will be easy, for any possible future repairs. Please and thank you. Here's a picture of what i have so far.  Unsealed it in plastic so oil and crap won't spill or get smudged. This damn things worth it's weight in gold.              Thanks Jeff                2007 Yamaha big bear 400 IRS.       YFM40FBW

      Yesterday I got a UForce 1000 as my first bike and I am wondering if there are any owners that could advise where I can find budget parts and accessories for it.
      I tried looking StarknightMT, but the filtering is a bit unreliable, so direct links or exact names are much appreciated.
      I'm mostly interested in sliders and side cases, but any advices for "must haves" are welcomed.
      Thank you!
