I replaced the one way starter clutch on the 03 400ex I just picked up and got it running.  I took it around the house and then brought it into the garage went back about 10 minutes later and started it and it idled for about 3 minutes and made a clunk and shut off.  Now its doing the same thing as before the one way clutch was replaced.  What would have made it do that?  Also i dont know what all has been done to the motor.  I was told it was bored and piston shaved.  I do nopw it sounds like the valves need adjusting.  Any ideas on why the one way clutch would brake like that?

I think the  sprag ( one way clutch)  is being blamed for another problem.  I can't tell what  is  making it stall  after  idling  for a few minutes, but I very  much doubt it is the sprag..  It is more  likely a fuel  problem . Is it running rich with a  lot of  carbon  black  building up  on the  spark plug?

It made a clunk and stopped.  Now the atarter just spins and the mottor doesnt kick over like it did when the one way was bad.  I think the one way broke again.

      Starter not staying engaged while cranking
      By HoldenBoy
      Hi all,
      Looking for some help on a starter/bendix issue. Can Am outlander 450 2017. While cranking to start, the starter spins and engages into the ring gear. After a few seconds the bendix retracts while still spinning and there is no damaged teeth on the drive pulley.

      Starter circuit cut out relay 1997 Yamaha Big Bear 350 4x4
      By crankin
      I have a 1997 Yamaha Big Bear 350 4x4. It used to start right up. Then all of a sudden it wouldn't crank. I have a schematic for it so I started tracing the problem. I had no power at the starter solenoid. According to the schematic the power comes from the neutral switch and through the starter circuit cut out relay. I cannot locate the cut out relay on this machine.. If I apply power to the relay it will crank with the start button.
      The neutral switch is hard to get to with all the brackets on this thing. I did find out from all my research that if I apply the rear brake lever it will start.
      Does anybody know if the cut out relay exists and where it might be found?

      Clutch engagement RPM on 2021 Cforce 400s
      By sunn
      The clutch engagement on my 2021 cforce 400s was approx 2700 RPM, very abrupt/not smooth.   I obtained a "kit" from RNG consisting of a blue painted spring (spring force unknown) with 12 gram weights, as measured on my postal scale.  Installation was easy; 18 mm and 30 mm (not 32 mm as seen on other writings) impact sockets for clutch housing removal.  The resultant clutch engagement was still up to approx 2500 and very abupt/not smooth.
       The original spring was labeled p/n 0951-1021 (specs for spring force 300/1600) with 18 gram weights.
      I called RNG who told me the kit should work fine for my ATV, but that wasn't the case as I found.  
      The RNG spring was slightly longer than the stock spring, but felt slightly easier at initial downward force but had more resistance than stock as I continued to push down.  RNG would not tell me what the spring force was.
      I then tested the clutch with the RNG spring and the OEM 18 gram weights with the resultant engagement RPM of about 2050 RPM, a little smoother engagement but still not good.
      I am really struggling to get any answers on the best combination of spring / weights to achieve a smooth engagement of maybe 1800 RPM.  Note; idle RPM is approx. 1600.
      I have searched all the forums and cannot find good information, and RNG appears to be not willing to share information.  What gives here?  Anyone with experience to share?

      1995 Kawasaki KLF220 electric starter not working
      By Asand211
      I've got a 1995 220 Bayou and the electric start does not work.  When I got it the machine was pretty rough but I was told it ran less than a year ago.  The key switch had been cut off and wires  twisted after the key was lost.  I bought a new ignition switch and repaired the wiring and it is working correctly.  It is in neutral and the neutral light is on when the key is turned on but I get nothing when pressing the start button.  I verified there is no voltage going to the starter from the solenoid.  The fuse in the solenoid is good.  Something I found that is odd is that I get positive voltage(12 volts) to the brown, black, and white wires that run into the solenoid when the key is on.  That doesn't make sense to me but I could be wrong.  I would appreciate any help I can get. Thank you in advance.
