1978 Puch Maxi Sport MKII - ZA50 - idles fine, won't go over 20-21 mph

erich g /

Hi-

Long time lurker, 1st time poster. I just found and bought a 78 Puch Maxi Sport MKII.

Runs, idles fine, in great shape. But will not go above 20-21mph on a flat surface. Takes very long to shift - seems to get to 12-13mph fine, but then takes awhile to get to 14 and shift into 2nd. Replaced Tranny fluid with type F, has new gas, new plug.

Any ideas? Here is a video - seems to make a funny sound when the revs get high - both in 1st and 2nd. Cleaned the carb, jets, intake port, exhaust port, muffler. Confused...
