yep read the manual cyclewriter, it says crack the line, and banjos are not truly one use, only if the get to crushed, or seep I already explained my confusion because of the model year. I've been doing this long enough to know that unnecessarily messing with a perfectly good banjo bolt is a bad idea. Apparently, so does Yamaha since they designed a way to avoid it on later models. Not only is there the very real chance of leakage from reusing the crush washers, but as Gray pointed out, the pipe is easy to damage from improper torquing or twisting of the brazed joint. The slightest deformity of the banjo fitting will often result in a leak that can only be fixed by replacement of the pipe. As the OP pointed out, he now has a leak at this fitting from trying to reuse the crush washers. This practice is even more likely and dangerous when done with brake line fittings. Trying to reuse a 20 cent part is beyond foolish, IMHO, no matter what the manual says. Service procedures are often revised from one model year to the next, and a manual can have info in it that is no longer accepted as proper procedure. Unfortunately, there's no way to update the manuals already out there. That's where forums like this one come in handy.
