Those OEM 12HT pistons are (apparently, so I've been told) not the best. The ring grooves are known to 'grow'. I bought a 12HT recently and it was recommended to change the pistons as a matter of course before fitting the engine. There are better aftermarket pistons available.

GBENTINK knows a thing ot two about these engines - check his thread 12HT performance build.
