How is it possible to have such a 5 mm difference on new pistons' dimensions?alpa a écrit : Check again chamber cc. If they are that different then check piston crown thickness. If you have let's say 5mm of thickness then remove some material from the top to increase the cc. You don't care about pistons, at the next rebuild they'll be worn.
It seems huge to me...
Not a specialist but that will certainly substantially impact the weight of each piston and hence the overall balance.spacecadet a écrit : If I change the pistons on only one side, won't that cause imbalance because of the different weights on the two sides?
Might require a rebalancing of all the pistons/rods system...
