Engine, (150 cc Non-injected 5 Port) for No Electric Start for Scooters & Mopeds

150cc Non-Injected 5-Port Engine for Large Frame Scooters and Mopeds

This 150cc non-injected 5-port engine suits large frame scooters and mopeds built from 1959 on, with the exception of the Vespa GS150. It is a good option for riders who want to replace or upgrade their current engine. The fitting process is fairly simple, so it works well for home mechanics. It is also one of the easier scooter engines and engine units to swap at home, which helps you get back on the road without a long delay.

Engine Features

The lighting system runs on a single unregulated wire, so the coil can be mounted in several places on the frame. The engine also includes an exhaust and a specific carburetor setup: a 40/130 idle jet, a 160 air corrector, an E3 atomizer (mixer), and a 92 main jet. Together these parts are meant to help your scooter perform as intended.

Installation Requirements

Fitting this engine to 10-inch scooters requires a voltage regulator and a Ducati-style CDI. You may also need the EIKH1 wiring harness and the 89471 switch, especially if you keep the original harness, which has no CDI. Note that using an 8-inch wheel changes the gear ratio, which will affect RPM at speed.
