We had a yard sale last year and I had my old OEM grapefruit launchers laying on the ground with 20 bucks on them. Guy walks up and asks me about them and I say they are off of my Busa. He asked me what size engine was in the bike and based on his prowess to date, I just said a 4 cylinder. He got a big grin on his face and said, "Mines a four cylinder too". He hacked them up and put them on a mid 80s toyota or nissan (don't remember which). Welcome to the south....
Still waiting for TwoBros to come in here with said story...
