      It appears that the Service Manual thread at top of forum is dead as all the links no longer work.  I'm actually looking for service manual for a 2000 KVF300 Prairie that I just picked up.  Does anybody have link to one that they can share, or know where I can find one?  Thanks in advance for any help.

      Recently bought a Polaris 425 Xpedition. Main issue is that the quad randomly misfires sometimes. ONLY does it at idle. Everything sounds good. What should I look for? Haven't checked the plug, seems a bit hard to get to, not sure. Headlights flicker at idle as well, is this a sign of a weak stator? Help?

      Working on my oldest son's buddy's 2000 Big Bear.  He was having some power loss at WOT so i thought it worth while to clean the carb and put at kit in it...or at least clean the OEM jets and use the new orings that come in the kit.  It starts and idles like a champ, but dies and wants to backfire with any throttle at all.  I assume lean because it will run decent with the choke on. Air screw adjusted fine, nice crisp idle.  This one has fuel/air screw, low speed jet, mid jet, and main jet.  I was assuming just trash in the low speed circuit so pulled it and cleaned again, still does the same. 
      Two questions I guess:
      1. Does it sound most likely trash in the off idle circuit?  This one has a few more passages and jets than I'm used to...and a darn diaphragm.
      2. It now really wants to leak at the bowl drain screw.  It doesn't seem to tighten enough to completely stop the flow.  Seat looks good, screw was dirty but cleaned up fine with a touch of 2000 grit paper.  First for me.  Any idea here?

      Just picked up a 1989 Big Bear 350 for $250 CAD. Bike was running but lost crank and spark. They've installed a new coil, a couple relays, and installed a Ford starter solenoid in place of the original. Now it cranks but has no spark so they sold it to me. Does anyone have a wiring diagram for this bike so I can test some wiring. Also any ideas as to direction to head would be nice. Lots of things have been hacked together so I know it probably wont be to easy. The ignition switch was replaced with a toggle switch, I already mentioned the Ford solenoid which 1 of the small wires was not re-installed, and a diode or something was removed from the oil temp sensor wire. I'm sure I will find more so a diagram would be amazing.
