I have a 1999 LT500F quad. When you hit the throttle it won't rev up and back fires. The weird issue is when you hit the starter button the engine revs up perfect??? Is this a wiring, surge issue or part malfunction?? Any help or recommendations will be greatly appreciated. Thanks

It will be a problem with the charging, the regulator operation in particular. If you turn the headlights on you will probably find it makes it slightly better too.

Check your battery and charging.

      Timberwolf 250 starting issue
      By Jdeaton011989
      Hi all. I have a timberwolf 250 2nd that will not start.. I thought it was out of time bc the guy I got it from said it just quit on him. The tensioner had a nut welded to it and it was like2 teeth off. I installed new tensioner and chain and it still will not start. It has fire and it will not hit off brake cleaner. It has compression. Haven't put a gauge but I'm sure it will crank and run with what it has. I double checked my work and it's still in time. Spot on. Both valves move. I'm about to put a feeler gauge on them and I'll cone back but other than that any ideas?

      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.

      Recommendations for must-have tools for maintenance and repairs.
      By DexKing
      Good day everyone!
      I am pretty new to ATV/UTV/Small engine repairs and would like input on your absolute must-have specialty tools for maintenance and repairs. Aside from the obvious wrenches and sockets, what are some more specialty type tools you use for troubleshooting? I don't plan to open a repair shop or anything, I just do this as a hobby. Looking forward to your responses!

      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?

      honda trx 500 fm foreman 2012 no start issue
      By gordonmacritchie
      on my honda trx 500 we have no power to the ignition switch for starting or ignition
      we have lights and horn working
      all fuses are fine
      have traced through the harness and cant find any broken wires or bad connections
      from what we have gathered so far the pgm fi unit is not sending any power to the fuel pump relay to power everything up.
      if we put power direct to the ignition switch plug then everything works but wth the key in the off position.
      does this sound like a faulty pgm fi unit?
