Thanks for posting that! I got a bid in on the heads. Arias can make those Pistons new for US $550, so I didn't bid on them. Might change my mind later though....those Pistons are tough to find. The one is missing a ring, FWIW, TLM in the Netherlands has ring sets available....
Go get 'em. Your next project awaits you. ;-T
I've got a second set in my stock bike if need be. Let us know how it turns up.
