What happened?

Maybe now isn't the time, but while I understand the minimum ring gap, but the maximum bewildered me. When I was doing a Yamaha Raptor top end I bought rings and a piston from the Yamaha dealer. Came home, slipped rings on, slipped it in, nope, too much gap. Return, test, return, test, and every one was outta spec.. And they said Those are what we use... But I wouldn't, because the book said they were outta spec. Anyway, the owner had seen me so many times he asked what was going on. He told the guy to order me a matched up piston and ring set. I didn't even Hafta pay the kinda uncomfortable difference.
So, what would be the problem with a bit wider gap? Kiss off some compression? Would it tend to score the cylinder?
