A lot of you want to tune your new fuel injected monkey but the limitations of the EFI prevent this. So we have made this kit that will plug and play into the original wiring loom.

Please check that wires in the plugs line up with the correct wires on bike loom

2 parts to the kit

1 x 4 pin D/C CDI (choice of silicone cover and switch)

1 x Micro wiring loom

1 x Performance coil 12V (choice of colour)

All prewired with matching plugs to suit the Rojo EFI Skyteam Monkeys

Carburetion

1 x 22mm oval bore pre jetted

1 x 22mmmm Manifold

1 x Force air filter choice of colours in the drop down.

1 x Throttle cable

1 x Flywheel "EURO 5 ONLY"

If you also want the DAX fuel tap kit for this conversion please see product code 3185

You will need to change the rear sprocket too as the 50cc gearing will be to low and will end up bending valves

Why have we made the kit.

Well if you’re happy with the stock bike with EFI that’s fine, but when you want to run a free flowing exhaust and gain more mid to top end power with the option of using taller gearing then you will need this kit.
