Hi ELSINOREYZ,
                     Dropped them a note via there website about 2 weeks ago, maybe they don't check it (no response to date) but in the mean time got a 1.00mm of evilbay, still chasing a .75mm will probably have to be Yamaha. Thanks for your suggestion

Almost every bike shop deals with Serco. Should be around $130 for a piston kit, less if you're friendly with the shop.

And look on US Ebay for the piston if you want to go genuine. But like always, don't buy just a piston 'cause the price of rings through your Yamaha dealer will make you cry.
