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.

      2000 Honda 400EX Backfires
      By Trent Finnessey
      I’ve got a 2000 400ex with a dg slip on muffler, it came with he stock muffler on it but the previous owner had the dg in a box so I put it on. I’ve been riding it for the past month and a half and every time I let off it backfires, and the other day the backfires got way louder, 2x louder! I’m concerned that I may hurt my motor? Why does is backfire??? Thanks

      '03 Honda Sporttrax 400EX Carb issue.
      By Dumass
      My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area. 
      Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.

      1987 Honda TRX250 No Crank
      By Arizona
      I recently bought a 87 TRX 250 not running of course, the owner had a brand new Key Switch on it.
      I think it is the wrong one or wrong wire colors as the colors dont match up with wiring diagram i downloaded for it. 
      anyone have a pic of their ign switch wires where they connect with the wire colors for that model? I ended up leaving the black/w stripe and
      green wire disconnected in order to hot wire it for other testing but would like to know as the colors dont match diagram.
