Troubleshooting the ATC250R

The Honda ATC250R was in production from 1981 to 1986. These ever-popular all terrain cycles are legends in the industry.

Decades after their production halted, they still grace the hills, trails, tracks, and dunes of the world. Here we will attempt to explorer essential trouleshooting tips and information for the 250R. Much of this info pertains to other Honda ATC's as well.

Troubleshooting is defined as finding, tracing, and correcting faults in an electronic circuit or mechanical system. The ATC250R is a straightforward, yet somewhat complex all terrain cycle. Knowing the basics of operation can save you some headaches down the road as many electrical troubles or fuel delivery problems are simple to diagnose and repair.

If there were only one piece of troubleshooting advice that could be listed, it would be to start off small and simple. Check the basics first before proceeding into complicated territory.

The Electrical System

The electrical system of the ATC250R tends to be simple if you understand ignition systems, if you don't you may find yourself scratching your head or overthinking the problem.

Knowledge of basic electrical circuits is a plus. The ability to use a multimeter to test for ohms (resistance), volts (voltage), and amps (current flow) is a necessary troubleshooting skill. Believe it or not, you can still use a multimeter effectively even if you are not a licensed electrician. All it takes is a little bit of training.

For example, the ignition coil, a typical area of concern, is easily tested with an ohmeter. Same goes for headlights and tailights, a simple ohms test will verify the state of the component.

A spark plug wire can also be tested by a simple ohms test and so can your tether and kill switches. The use of the appropriate 250R schematic is a always a help, but it many cases it isn't even required if you can perform a resistence check with any digital or analog ohmeter.

The Fuel Delivery

The fuel delivery system of the ATC250R is another somewhat simple system if you understand carburetion and basic two stroke engine operation.

Many fuel related problems are often overthought. The solution, more often than not, is something as simple as a clogged fuel filter or a dirty carb just crying for a cleaning.
