HOW TO DO ATV TROUBLESHOOTING?

• Learn how to do some basic Atv troubleshooting,
  and you'll spend more time on the track and less
  time in the garage.
• Like any vehicle, ATVs can have problems,
  hopefully when you're close to home or close to
  the tow trailer.

• Even if you are not mechanically inclined, you
  may be able to diagnose the problem and fix it
  yourself, possibly saving you some money on
  repairs.
• If you suspect that you've got a serious
  mechanical problem, check your ATV insurance to
  see if it's covered before you head to the repair
  shop. Troubleshooting an ATV that is having
  maintenance problems can be done easily.

  from rear axle, metal popping out of Bearings

• (b) Skirt broken off piston, hole in crankcase -
  Both result in engine not running, full
  compression. No crankcase pressure, which is
  needed for 2 stroke engine.

• PROBLEM Broken Piston Skirt-
• (a) Piston fatigue from scoring or Excessive
  piston to cylinder clearance - Repair or replace
  cylinder and piston
• PROBLEM - Melted Piston Top-
• (a) Engine overheating - Low coolant level in
  radiator (liquid cooled)
• (b) Lean air fuel ration - Restricted cooling
  fins (air cooled)

  jets.
• (d) Incorrect ignition timing - Repair as needed.
• (e) Incorrect spark plug - Adjust timing per
  specification Install correct spark plug.
