Aw shit! I sure hope 31mm isn't the size my 1980 KZ440ltd needs. If that's the case, I'm gonna cry. One thing about home-made clip-ons, I have tried to make a set myself, using a chopped down top clamp and some bar clamps brazed onto them. The brazing worked great, but the "test" I did on the brazing, aka hammering them on a table top, broke the casting. Ha ha. But now I'm gonna try on a chopped up bottom triple. There's so much swapping of front end going around, that plenty of '70s-'80s front ends just aren't gonna get used. Kinda sad, chopping bits up, but hell when you KNOW it's not gonna get used, then so be it. So maybe I'll console myself by grabbing a spare KZ top triple and an alloy mountain-bike bar. Only this time, instead of messing around cutting an insert fit on the parts, I might just weld the crap out of the things and file all that lumpy goop down to shape. I was worried that the braze material wasn't as strong as the casting, but it was the other way 'round! Those guys right there on the other hand, they look just like a pair I saw listed for a hundred and fifty the other day. Minus the paint of course.
