With that being said there are parts of the engine sitting in a cardboard box and I'm not sure if it would be worth it to repair the original motor or put something new in. I talked to a bike buddy of mine and he said that he thinks it would be a good idea to find another motor to put in it, something newer and well taken care of.
My question for the community here is, 1. Is it possible to put another motor in a 1960s-70s large frame Vespa.
And 2. If so, what would be a good option for a long lasting engine to put in it. For the sake of not spending money up the if a newer engine would be cheaper than an older one I would have no issue with mixing the old with the new.
