new at this need engine size help
I just bought my first engine. Ordered it online as a 80cc kit. When I opened the box the sticker says 69 cc made in China.
I called the shop that sent it thinking they sent the wrong one.
I was told that its the difference in the way they measure them.
Is this true or am I being ripped off?
I need to know before I mount it just in case I need to go kick some a##.
