Hugh Weaver’s Bultaco.com had been offering some odd-sized NOS Tarabusi piston kits @ $75 for a while on their website, which is one heck of a steal. The list fortunately included the 66.5mm size, which will work fine with my relatively less common 200cc cylinder after a 2mm overbore (which I am guessing it needs, anyway). Recently, however, they updated their site and the offer disappeared. I began to get worried, so I called them and they said yes, they still had them, and the price was still $75. I went ahead and ordered one, even though I am nowhere near the engine-building stage, just to ensure I won’t have to pay through the nose for one for when the time comes.
