Hey everyone so finally at the point of starting to put my 68' Commando engine back together (crank bolts are on the way) Cylinders been honed an is still stock bore. She was running a set of JP Pistons, when Pete Lovell honed an skimmed the cylinder for me he recommended changing the rings, just wondering what's everyone's preferred supplier for rings on JP Pistons.

Cheers,

Tom
 
stick with the JP rings JP 750 commando pistons have a weird oil ring width 2 x 1/16" for compression but oil ring is a 4mm wide

OEM rings are 2x 1/16" compression oil is 5/32" wide ( 3.969mm ) so may have too much side clearance in land
