o2 sensor wrench size?

It should be 22 mm unless it has been upgraded with a new ECM, then 14 mm in a 22 mm adapter. That's according to Honda Service Bulletin # 70.

Thanks folks. When I first discovered this forum about 6 months after I got my BF 225, the folks on this forum helped me greatly and graciously. No one was snarky, like you see on so many other forums. Over the years, many folks have helped me deal with maintenance and engine issues. All that I do is try to return the many, many favors I have received. Special thanks to Hondadude Mike and Professor Jimmy.
