Lester Mags, making them tubeless
I just picked up a Guzzi G-5 (949cc, 5 speed) that is fitted with Lester Mags. I can't see paying the weight penalty of mags, and not having them set up for tubeless.
Has anyone ever set up a late 70's early 80's set of Lester Mags for tubeless operation?
I have converted many a set of the standard Guzzi cranked spoke mags of that same era. Since the inside had no flat machined around the stem hole, I always simply tapped the hole for a 1/8 pipe thread, and fit a tank valve. Works amazingly well. I'd prefer to not tap the Lesters,
Does anyone know of a tubeless valve stem that works in the Lester Mags?
