5-port 150cc motor for 4-speed scooters. These engines are so popular, we can barely keep them in stock! Why rebuild when you can install a brand new motor that's faster, smoother, and more reliable than the original?

This engine has electronic ignition, and you might need to change your scooter's wiring harness to get the lights working (see part EIKHK). It has a single unregulated wire for lighting. You'll have to mount the coil somewhere on your frame.

PLEASE NOTE:  These engines are a late model PX type electric-start, oil-injected engine.  They will fit in large frame scooters 1959 and up, except for GS150, WITH MODIFICATIONS.  Provisions need to be made for the oil injection and electric start systems. Since most early model Vespas did not have these systems, there are no wiring diagrams or schematics available.  If you're good with electrics, and ambitions, you could make a custom harness with a battery and never have to kickstart again!

The short wiring harness to hook the CDI unit to the engine is also handy: ENGHARN

Proper break-in instructions should be followed and can be found in the Manuals tab.

Brand: LML

Fits: Any large frame scooter 1959 and up, except for GS150
