20 Most Recent 2010 Yamaha WR250R Questions & Answers

Hi, Sergey it should be noted that the reasons your check engine light or CEL stays on constantly or flashes and your bike will or will not start and may turnover or not, these conditions will vary from bike to bike depending on the year, make, and model and you should always refer to your owners/service manual for proper diagnostic procedures. It should also be noted that any type of prior work done to the bike or an abnormal event occurrence such as adding accessories, electrical curiosity or adventures, laying the bike down or crashes, stolen and cut ignition wires, rainstorms or bike washings just before CEL light issues started can be significant hints or aids into tracking down the gremlin, also keep in mind that your CEL comes to life if anything, and I do mean anything isn't 100% with the ECM such as parameter spikes. This means that you could be staring at a major repair, or something very minor, like your speedometer sensor, is contaminated and needs to be cleaned.
And the usual suspects are:
1. Severely discharged or a damaged battery check the terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary, you should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Faulty charging system.
3. Faulty system sensor some models have up to 40 sensors
4. Faulty safety switches: run/off, ignition, clutch lever, neutral, side stand, tip over, fuel, and or their connections.
5. The engine got wet in places where it doesn't like to get wet.
6. Faulty ignition circuit spark plugs, coils, cables etc.
7. Broken wire or worn insulation exposing wire to a ground situation especially inside wire harness at tight bends around fairing brackets, under dash panels, under fuel tanks over cylinder heads etc. Many harnesses are open on the ends that will allow water to enter and accumulate at v-bends.
Dielectric grease and contact cleaner are your best friends for wire/cable/harness connectors, look for corroded, broken, or loose pins/sockets. Run speedometer diagnostics and check for generated fault codes.

The Road Star holds a TOTAL of 5 Litres/5.3 US Quarts of oil, but you don't use that much unless you strip the engine down.
Normally you would use:
4.3USqt/4.1L if you change the oil AND the oil filter
3.9USqt/3.7L if you change only the oil and NOT the oil filter

Do You have a test light or a multimeter? If so, how are you with diagnostics. I can walk you through testing this circuit if you want. Is both the high beam and low beam out? Basically you need to confirm (+) Batt. power and (-) ground at the head light first. After testing the headlight wiring then move to the left handle bar. To the Dimmer switch and access the contacts inside. This may not be easy but ask first if your not sure. Burnt out bulb and worn out dimmer switch is the most common failure. Only testing will confirm it.

The clearance and procedure to adjust is in the manual. If you don't have it go to the Yamaha dealer and ask.
