Karl, I bought two bags of dynabeads months ago - to use whenever I had the new Angels mounted.
But, talking with the service guys at time of tire change - they both said they had no idea what I was talking about.
So, I still have them.
So, while I have the stem out - wouldn't it be a good time to pour in the 2oz. recommended for my scooter?
BTW - probably going with a COLBY valve stem - which can be installed from outside the rim. A couple of off-road bike riders on the Vespa forum PM'd me to say they use them with good results....as a "permanent" fix to ripped off stems.
If I don't use the dynabeads I'll add a small wheel weight to the other side of the rim.
