2002 Bear Tracker timing chain noise, poor idle- tensioner failure?

At the end of last summer, my 02 Bear Tracker began to run poorly- long story short, the air box cover HAS to be on and sealed... now it runs ok, except it idles poorly, and I began to hear a "chik" noise on deceleration. This has become obvious chain noise hot. Runs great at throttle, poorly at idle. I pulled the cam cover- and the chain has no appreciable slop.... could this be a failing ratchet in the tensioner? Anyone seen this? I'm about to pull the tensioner. I COULD install a manual one, but if the factory one lasts several years, I may go back that way. I'd rather ride than wrench. FYI- ASE Master since 82, blah blah blah- small engines are NOT my bag. All replies GREATLY appreciated!

      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!

      Im aware that this relay needs a positive (+) and a negative (-) to activate the other side. The blue wire is the neutral wire so when in neutral it gets ground. The green wire is from the parking break; when you pull the break in it gets ground (-). however one of those two needs to be neutral so that the positive from kill switch can go to the starter relay. The ground from the starter relay is from the start switch. Which one (neutral or parking break) should have a positive (+) voltage?

      Well while I was waiting for new parts for the choke, I decided to adjust the clutch. When I removed the lock nut, I found the guy I bought it from or someone else had stripped the threads on the adjustment rod. I couldn’t get the adjustment rod to turn without putting a pair of channel locks on the screw driver, this was telling me something was wrong. So now the rod pushes in and out and spins freely too freely. So guess I’ll have to take the clutch housing off to see what’s going on and replace the adjustment rod, it’s threads are beyond repair, and there is something going on with the adjustment rod. If there’s another way please let me know. The further I go the worse it gets. Thanks for any help.

      Hey all, I just picked up this Massimo UTV for $500. Got it home and replaced the starter solenoid which successfully got power to the starter. Starter spun but engine didn't turn over although the engine is not locked up. I thought it was a bad starter. Got a new starter put on today and it does the same thing. Pulled the clutch cover and saw the engine is trying to turn over but something is slipping and not letting it turn over. I figured it must be the gear on the engine that the starter turns. Where can I get that and can it be replaced without pulling the motor? And am I correct that that's the issue? 
      Thanks!
