if you cant find the +30 than order +40 and file fit.

does anyone carry new Norton rings at .030? with a 3 piece oil ring?
 
If you can't get them from Norvil, I might have a set in the garage. They would be for early Powermax pistons that have a shallow oil ring groove though.
 
thanks but these are the stock JCC pistons, normal oil groove. Do the Norvil rings have a 3 piece oil ring
 
Never seen JCC pistons in +030 ? check the internal casting numbers

plus 30 are normally old stock Hepolite pistons
 
I've never seen JCC pistons for 750 Commandos in anything but standard, +.020, +.040, +.060. and +.080. Could be they made a special run for someone like Norvil, but I doubt it.

Might be GPM. They made +.030 at one time.
