Your engine is not original it has been changed to a e50 I guarantee it, theres no way a Stock E50 could’ve pulled 18x40 gearing let alone a 1.5 hp e50 maxi that comes with 15x45 gearing that’s even lower than 2HP 16×45 Gears
A stock 1.5 Hp za50 Newport II still comes with 18x40 gears,
I had or worked on several red Newport II’s over the years and I got one right now, They come with the good second generation za50 engine that engine Vin number matches the frame, never come from the factory With a e50,
For the coil to be on the frame it’s a specially made Za50 frame that has the coil mounts Welding in at the factory because there is no coil mounting slot on a za50 like a e50 engine has.
Look at the one I have now that I’m going to be restoring sometime it’s a za50 that the Vin matches the frame.
Some Newport II’s especially the black ones have normal 17 digit Vin numbers like a car and engine number doesn’t match but most red ones don’t but still come with za50 engines
A 1980 second generation puch Za50 2 speed is far superior to a 2speed tomos engine and after you flip the second gear clutch it shifts like a Chevy powerglide transmission with full and partial throttle kick down making it a blast to ride by keeping you in the power at all times
