My check engine light comes on after a few minutes riding at 60+ on freeway. It does not come on riding around town. I checked and there are no error codes shown in historic data. The light stays on until I turn the bike off and does not come back on until back on freeway. Suggestions? | ||

I'd check the O2 sensor. As an experiment you could turn if off (via ECMspy) and see if that stops the CEL from coming on. | ||

No historic codes - what about current codes? There must be a code for it to be coming on. | ||

Any change to how it runs? | ||

No change in how the bike runs. After I turn it off, when I turn the ignition back on, the light comes on for a few seconds like it aways has and then turns off. Riding around town for days will not cause it to come on, but as soon as I hit the freeway, on it comes. I checked for error codes using the VDO software I use to do TPS reset. Nothing current or historic error codes. I do have a race ECM. | ||

It sounds stupid but check your oil level. Dunno why but mine would do what yours does w/o the oil light coming on. It was a little low on oil. I topped it off & the condition has not recurred. I also have the race ECM. Chris C | ||

I may have fixed the problem. The gasket or the rear cylinder header had evidently disintegrated and exhaust was blowing by. Replaced the gasket (sort of since it is still leaking a little) and a freeway run yesterday did not light up the CEL. |
