So I have a 1997 Yamaha wolverine 350 4x4 and am experiencing a clunking noise at low idle and it only happens at random. It seems like its coming from the lower end. Engine seems to hesitate when it happens. And ideas!? Thank you

I checked the starter clutch and it seems to be working properly. It's coming from inside the case towards the front on the right hand side if you were to be sitting on it. Looks like the only way I may find out is by opening it up. I do plan on re-building the top end this winter.

Hmm, It strikes me as odd that it only happens randomly. Id be eyeballing thing that change their mechanical position in a different manner after each start-up. Could the flywheel be loose? Maybe the stator plate screws loosened up? Exhaust pipe cracked or loose causing a random leak? Id be checking external stuff before jumping in & cracking the case upen. In my experience a bad crank bearing or something like that usually doesnt go away then come back. Good luck with it though.

      2 problems with 2000 Timberwolf 4x4
      By Tim Keiper
      1st problem, Does anyone know where I can find a stock carb for my Timberwolf, I have tried two different aftermarket carbs and they both suck. The machine runs great until it gets good and warm, then it keeps stalling unless I feather the throttle. it will even stall while I'm trying to go from 1st to reverse or vise versa. I took it to a buddy of mine who is a bike mechanic for years, and he told me try to find a factory carb. When I look online from dealers it says "NOT AVAILABLE" anyone have any suggestions ?
       
      2nd, The small tab on the rear axle for towing is to short for even pulling my small yard trailer, I can't even turn a little bit and hit hits. I tried making an extension which worked great as far as length, but it bends the tab and then the extension drags the ground. I have an idea of what to do to fix it, but wanted to see if anyone else has had this problem and see how you solved it.

      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.

      1999 Yamaha Big Bear 350 4x4 no spark
      By Kaz
      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!

      Need help! 1987 Yamaha Moto 4 350
      By P_syko
      I’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto 4 350. It has good compression and fuel, but no spark. I’ve looked high and low trying to find how to test all the components of the ignition system, but can’t find anything. This has a new CDI box on it, but I suspect it might be the stator. How do I test the stator on this? Any help would be greatly appreciated!

      2008 kazuma 800 4x4. i need wiring help. no spark
      By carkivey3
      i just picked this up. was told ran fine but overheating issues led to replacing head gasket and head. has not ran since. he is not a mechanic but helped someone else who he could not get back to finish job, got aggravated and put up for sale. i was thinking timing issues. i have 110-120psi on all 3 cylinders so i think valves are correct. dont know about distributor yet. however i have no spark. i have no power going to ignition coil. tried to follow white wire but gets lost in wire harness. does anyone have a wiring diagram? can anyone tell me what conditions have to be met before starting. motor turns over so i would think all safeties are met but you never know.
