Product Description

Honda GX340 11HP Petrol Repower Engine (Recoil Start GX Series) for Generators - J609B Tapered Shaft, 3 Year Warranty. The GX340 Tapered shaft is specifically sold to replace a power generator engine.

The Honda GX range is used by reputable Generator manufacturers like, Genelite, Powerlite, Dunlite and Gentech.

Fuel Efficient, High Output Operation:

A digital CDI ignition system with variable timing and an increased compression ratio combines with the GX340's Precision Camshaft design to offer precise valve timing and optimal valve overlap for better fuel efficiency.

It draws on decades of Honda engineering with its OHV design, delivering increased efficiency and optimal power transfer where and when you need it.

The use of lightweight, noise-reducing materials and a forged steel crankshaft & rigid crankcase results in an exceptionally quiet engine - an improved piston design reduces mechancal noise, with an overall reduction of engine noise by up to 5 dB.

Smooth Performance:

The GX340 offers precision-engineered components resulting in lower vibration, and a Ball Bearing-supported Crankshaft for greater stability. It also offers an improved piston design and a heavy duty balancer shaft to deliver smooth performance.

A large capacity, multi-chamber exhaust system and sophisticated air intake system also makes for an exceptionally quiet engine.

And with a simple Throttle Control, large Fuel Tank and Automotive Type Fuel Cap, Dual Oil Drains and Fills, an easily accessible Spark Plug and Heavy Duty Recoil Starter, the GX340's features go on and on.

3 Year Warranty:

The GX340, just like the entire GX Engine range, is covered by an extensive Honda 3 Year Warranty.
