I’ve just bought a 78 maxi S and I want it to go a little faster. Right now it’s bone stock, I’m looking at the airsal T6 50cc barrel and the airsal 65cc barrel. Which one do you think would make more power.
I’m going to pair it with a 14mm carb or 15mm bing carb whatever I can find cheapest.
Previous owner did put a one piece bi turbo exhaust on it, so I’m going to leave it as is for now.

Hi, I’ve just bought a 1978 puch maxi S and I want to put the PSR 70cc 6port cylinder on it. Trouble is the OM one is sold out and the NM one is cheaper and in stock. Will I have any issues fitting a NM to an OM case? I don’t even know what the differences are tbh? The look the same other than the inlet.

If someone could advise me I would be greatly appreciative.
