Mofast is a performance parts company which sold moped parts in the 80's or early 90's. Parts carry the mofast "For competition use only" decal. Little is known about this company and the parts they sold are fairly uncommon. Much of the info here is based on speculation based on images, little info exists.
Puch Maxi and Magnum

A pipe of hand welded construction featuring a serviceable silencer. The powerband is speculated to be for high end performance. Construction is sturdy with a chrome plated finish. There are horizontal and angled header flange versions of this exhaust to fit either the maxi or magnum.

This is a 19mm dellorto Ua 19 carburetor. The carburetor likely came with an intake manifold and a aluminum velocity stack.

The 19mm intake is of cast aluminum construction and matches the mofast carburetor.
