85-87 ATC 250SX Service Manual.



Because of their reliable design, relatively simple construction, and ease of repair; ATVs are the ideal machine for maintenance and repair at home. With proper care and routine maintenance, your ATV will provide many years of reliable use. When repairing an ATV, most home mechanics will find them easy to work with and repairs quick and trouble-free.

Scheduled ATV maintenance should occur frequently at regular intervals. This routine maintenance should include changing the oil, inspecting the shift linkage - steering - suspension - coolant system - fuel system - drive belts - engine mounts, changing the spark plugs, and replacing the fuel and air filters. Having a quality service manual specific to your ATV will help you identify the parts of your ATV and assist you during routine maintenance and repair.

Doing routine maintenance on your ATV at home provides many benefits. It is less expensive than having an ATV shop do the maintenance. It prolongs the life of your ATV. And, it provides you a better understanding of the working components of your ATV.

Even with diligent routine maintenance, ATVs may require periodic repairs. In the event that you need to repair your ATV, it will likely be easier if you have been doing your own routine maintenance as you will be more familiar with the mechanics of your engine. Another asset that makes ATV engine repair easier, is access to service manuals and parts catalogues. Since you may already have a user manual that you've been using for routine maintenance, you need only assure that you have on hand a service manual for any more in-depth repairs/maintenance that may be necessary.

Your ATV will provide you with many years of service providing routine maintenance and servicing is carried out. Doing this yourself and at home will give you the satisfaction that you have saved money and prolonged the life of your ATV.
