you should check the engine ID plate and se if it’s a 1a, 1b, or 1d
in the case of a “B” 25 is pretty good. “A” was meant to do 25 but is often around 30 anyway. The “D” is higher compression and displacement and should be able to break 30 without a sweat. Sachs did incorporate a restricted pipe on some bikes. Check the header pipe and see is it reduces in size after it comes off the cylinder, The non restricted pipe should fit nicely. The other restriction unique to the “B” was the 10mm carb, again it’s easy to get around by buying a 12mm square bing.
