For E50 engines found on various Puch mopeds like the maxi, newport, magnum,pinto, swinger, murray and many others. 70cc size will increase power dramatically. "No replacement like displacement!"
ZA50/magnum mopeds will need to use a Puch maxi flat exhaust manifold style exhaust as the mangnum stock exhaust manifold is angled.

Straight out of the box ripper. Port timing on this kit is awesome, casting is
clean, and ports came already camphered on mine!
Out of box performance;
Airsal + phbg 19mm + estoril = 48mph (stock gearing) with a STRONG powerband
K-star + phbg 19mm + estoril = 44mph (stock gearing) with okay power
Dollar for dollar, best puch piston port kit you can run IMO
