Lamb cel

[Fast_Momo]

Hey guys,
My CEL came on with LAMB code while riding down a mountain. It was hot today but other than that the bike was running great. After coming down the mountain I let her rest for a second and restarted it. No CEL from then on. Any ideas? Possibly unburnt fuel or different running by engine braking for an extended period time?


I have a LV cat elim with FatDuc and no flappy. All else stock.

I think you answered your own question very well.
Others with fat duck have had similar issues.You could back of a tad on your setting if it bothers you.
I had an FJR that would flash a code if I ran at low RPM steady speed for more than 15 minutes.
Cleared up once I ran it out.
Doesnt sound like a problem.

Thanks Mr Mike. I figured as much, just was wondering if anyone has seen it as well. Possibly, and more likely, it was more of a value code since the ECU probably saw values past what is normally acceptable. This was probably faciliated by the FatDuc's offsetting.

With fatduc, my CEL comes on until the O2 sensor gets up to temp. It seemed come on every time I start it. No real issues in over 18 months.
