Hello folks I picked this gem up right down the street from me in Orange, CA on Sunday. It appears to be a YZ 490 converted to a trike. I am trying to figure out if this was a kit that was available or just a garage conversion. Forks and triple clamp are really nice. Someone asked if it was possibly an old 3B bike, which I doubt, but the original fenders are yellow. Any input or info would be greatly appeciated!
