I had just this issue with the Yo I bought. It too had a BB inspection window, which whilst handy was expertly fixed by Lee Cooper who replaced the whole seat tube. Check out the build history on my Yo, It’s so well done I doubt you’d ever know. Oh, and Lee made me some BOI forks too. I know he’s stacked out at the mo, but I couldn’t recommend him highly enough. Peace and love, H.
