Just been through a load of old spares and nearly all the barrels are good except in this area.
I remember my kx 125 did the same,left like a square edged section where the plating had vanished.
anyone had there barrels replated recently and if so where's best,was thinking of using "The Tuning Works" to get them done as ive heard stories where people have lost there barrels/take forever to get them back when they have dealt directly with the platers?
Cheers
Dave
