How about Oliver? Also only have a rebore with new pistons, that is to say the engineers rebore and hone exactly to the size of the pistons you supply them. Obviously this will change any crank balancing you may have had done. Otherwise give me the crank, and barrels, I can rebore, hone, supply pistons and have the crank dynamically balanced, all you have to do is open your wallet and I can surgically remove a considerable amount !!
