Guys and Gals:
Live on a steep hill and playing with me "new" ZA50 78 Sport MKII. I'm not particularly interested in top end speed, but I'd like to investigate the best way to get some more low end torque/power. This is the same model/bike I had at 15 years old new in 1978 and I weighed about 135 wet back then. I'm now 200, and surprisingly, this 41 year old motor feels pretty much the same as when I rode one way back then.
Is there any simple mods, or rebuild options that would get me to a reliable 20+ mph heading up a steep hill? With the 2 speed, It hits 15 and stays in first till I crest the hill. Considering the grade, this isn't bad, but if I could improve on this with some mods, that would be fabulous.
My thought was the 2 speed was the way to go with hills, but I'm open to building an E50 if it would be simpler and get me the same results.
If this is a repeat topic, forgive the dupe, and point me to some threads that might answer this question, assuming there is a good answer.
Also, is there anyplace that lists the history of Puch models and options up to their discontinuance? Are the Magnums so pricey just because they look more like a regular motorcycle, or do they have a superior drive train? Appreciate the patience with the "newby" questions.
