Motor Z140 140cc

A circle of skilled motorcycle engineers, lovers of personalized motorcycles, want to build a simple yet twin motorcycle with two engines and only one gearbox, using an efficient little-polluted carburetor, starting pedal to start the engine.

At last, complete to mount in a special frame that supports the two engines with only one box of gears.

180-degree displacement between one explosion and another in the ignition, with the two crankshafts cruising together (twin).

Could you guide us how to do the sparking for this twin system? With two spark plugs always flashing together, yet with a single command for the ignition timing on both the cylinders and the heads?

Just as on the Zündapp model KS 601 motorcycle year 1952 - four times and others since 1930!

We intend to use 15 "wheels, 18" tires, tapered and anti skid, using the same gauge on both wheels.

We wish a motorcycle with a very low barycenter, however with a good height away from the ground, with modified suspension to work more in the upper part of the frame, with piston loader springs, with the proper length and diameter, with double shock absorbers Action type Earless on the front and monoshock on the rear similar to Yamaha DT 180cc.

To make the experience constructive, we will pay in five people the installment, by bank voucher. After paying in full, we will get the full engine. Our choice was the Engine model Z140 140cc New 2016, or 2017.

What the competent engineers of this Company advise us.
