Pistons and crank

[STU666V]

Is there any way in telling what pistons these are?

Does this crank look ballanced or does the standard crank have these little holes in them? Not holes but like drilled marks on them,
Was told they are forged pistons, lightened and ballance crank?

Cheers for any info.

stuart cranks hav to be ballanced to make them run smoth or they would shack to bits ie same as ur wheels and the drill make is how they do it as for it being lightened there will be machined marks on it making bits smaller i would think as for the pistions look like cp ones ;-)

There are usuallu markings under the piston so you will need a better shot then that..
