Hello, I am new, I was on 3wheelerworld, and they had a modified yamaha 3wheeler with 350cc engine, but they said it was a modified 3wheeler, there was another one on the cover of 3wheeling magazine, july 82? but I can't find any info on it. It had a yellow tank and fenders, a triple tree like a 200x, if anyone knows what the crazy thing is I would love to know.
