So I bought my first moped, what I thought was an a35 engine because of the reed valve top end That was stamped a5. I just noticed the bottom end was stamped a52. Also has much larger transfer ports than the cylinder. (Noticed the ports earlier but not knowing anything it was overlooked) So is this an a55 bottom end? I've already bought an a35 70cc kit and pipe. I am just barely hitting 40 mph, most of the time I am around 38mph with 26 tooth front and 22 tooth rear. I currently have the top end off to fix a base gasket air leak and am waiting on new reed valves to come. Also and running a 75 jet on the stock carb but that will probably have to lower once I get the air leaks fixed. I am hoping fixing the air leaks will help with top speed. I would be happy if I can get up to 45. I really don't want to have to buy another kit if I don't have to. Additional info is the title and Vin say its an 05 targa but all the trim like the faring and side covers said ST so idk what I have. If anyone has any input or help is greatly appreciated.
