Pretty sure that's the spring for the decompression mechanism.  Without it, the dowel just bounces up and down in it's hole....not a great idea.  It's probably pressure specific also, so you probably need the OEM spring.

      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!

      I've been hunting for a rebuild kit or aftermarket replacement without success. Any tips? The OEM replacement is too rich for my blood.
