i have some standard never been on a bike [ according to bantom john
] A7 short stroke barrels and my predicament is I also have some hepolite +30 thou pistons and two sets of hepolite +30 rings. I want to use these pistons in a build but don't want to bore the barrels out that much it would be very wastefull. why don't I use standard pistons I hear you say,. I don't want to. I really NEED haha to use the hepos and I was going to use them in some +20s I was sold that turned out to be +40s has anybody in uk got any barrels super worn std or part worn +20thou for A7 they would be happy swapping for the standard ones?
