Tony, last year I built up a custom wheel for my Honda using a new spoke set from an aftermarket shop. I was curious so I asked if some spoke nipples from a Honda wheel would fit their spokes and they said NO! I emailed Barnett and asked them about Spoke gauges and their reply was that they started building their wheels "before" standard spoke gauges were available and so ALL of their spokes are custom sized. Same apparently goes for the rest of the wheel/spoke makers. If there is a current Standard that everyone is using, many of them don't know about it!!! Don't know what to tell you? I can remember back in the early '80s when I was working at a Yamaha shop I cut some spokes for the owner of the local Kawasaki shop and they worked?? Keep searching, maybe someone has the answers?
