I couldn't find any locally and they're $20~25 online. So I made my own. Figure I'll offer it up for the good folks at gstwins.
$15 shipped per banjo bolt.
$5 core refund if you supply the banjo bolt but not all banjo bolts will be compatible with your application...I actually had to make my own for my GS750.
$2.50 core refund if you supply the bleeder.
(means if you you've got a banjo bolt on hand that fits and a bleeder from an old junked caliper or something you could get a bleeder banjo bolt for $7.50 shipped)
Just thought I'd offer.
any pictures of how htis works?
I'll get one up tomorrow afternoon. I just slap a bolt in the lathe and cut it similar to a banjo bolt but I bore the center all the way through. I then bore the top out a bit further and put a 15* seat in it. Thread the bore and slap a bleed screw in there. It's easy to figure out if you look into how a bleed screw works.
