I have a 1978 PA50II and I need to get more power out of him. I have given up trying to find the Proma Circuit for the Camino or otherwise, THEY JUST DON’T EXIST. So I’m thinking about trying to fit a Biturbo on him. I’ve heard some say that it will go, other say no and others give me a non-comitial half-assed answer. I wanted to know if there were any success stories of getting a Biturbo on a Hobbit. I know someone who has a welder and if I take off the kickstand and stock muffler it looks like it will fit.
Ultimately the goal it to fit a Polini kit on him. I also wanted to know, if I did find a way to fit it, using my present cylinder, would I get screwed when I get the kit and find out I’ve cut the pipe too short or something like that? I don’t know if my wallet is deep enough to get the kit and the pipe right now and I’m thinking its smarter to get the pipe first.
On another note, what is the difference between the Proma for the Puch and the Hobbit? MopedShop.com has the one for the Puch but they’re a bunch of idiots. (I called them and they kept telling me they only deal in moped parts. Eventually I told him that the Hobbit is a moped, he asked what state I was in and then I heard him ask someone else, "Is a Hobbit a moped in Washington?") If I could get a pipe that wraps around the head I think I would have less trouble making it fit. But like I said the Proma Circuit DOES NOT EXIST.
