New piston

It’s a Wiseco item, brand new, and its on the Carillo rod now. It’s a flat top, 98mm bore, so it won’t be a brutally high compression, but if the motor is good we can up the performance a little later in the season. I used 3 Bond from Rex Caunt Racing (look thru their site, some lovely classics...) on the new genuine Yamaha base gasket. And then torqued down the new nuts onto new studs, with new washers from Slipstream and Kedo.

I also blocked off the oilway from the cases to the barrel, with one of the little plugs Alain made for me.

No piccies here, simply too boring!!
