Thanks for the scare! ;)

In the ranges I'm running, there has been a lot of data taken by others and it's not at all a concern to me. During warm up, my motorcycle runs in the 12s and low 13s. (Others have even disconnected the O2 entirely.) As I side note, I've been monitoring converter temperature and it hasn't risen or dropped noticeably. Interestingly, the temperature going into the Cat is much lower as the mixture is richened.

A misfiring cylinder with raw fuel entering the converter could do a lot of damage, like you mention, especially if there is an air leak to provide the amounts of oxygen needed.

Lastly on the issue of risk, the performance gains alone make a small risk (if it even exists) worthwhile. Flying is a risk, motorcycle riding is a risk, my age is a risk. I think I'll just find the best points (the high low limits of Lambda) and enjoy the smooth performance and riding when the spring comes to the Northeast. I should have things worked out by then!

Happy Holidays to All,
Roger
