[T2] weighing and balancing the piston - advise

[Christophe Guilbert]

Hi ,

I was weighting my new piston to balance them.
3 of them has the same weight but one  is 0.3 oz less than the others . 
should I remove 0.3 oz from the 3 pistons by grinding the inside of the 
piston pin ? would it make my engine last 100000 miles if I balance it 
that way or it won't make any difference.

Thanks
