Motorcycle question
So Ricky is looking for a cylinder for his bike and there's a montage of Clifford and Ricky going around junk yards to find one. They seem to be looking at single cylinder but suddenly Cliff hands Ricky two units, one a single cylinder and also a two cylinder. The two cylinder is the one that Ricky seems to have been looking for all along...
I'm not a motorcycle guy but I have spun a wrench on my own cars, what the heck is going on there? Is this is a mistake or can a motorcycle somehow work like this? Again, take it easy, I know nothing about motorcycles. It just seems odd to me.
