How to Remove Your Mk2 Mini Moto Engine
By Matt Tong
Many mini moto modifications will require you to remove the engine from the mini moto. This is why I have produced the following guide.
Firstly you will need to remove the mini moto’s fairing.
Start with the seat fairing, unscrew the four seat screws and remove the seat. Unscrew the screw at the front end of the seat fairing and remove the petrol cap. The fairing can now be lifted from the mini moto. Replace the fuel tank petrol cap and remove the fuel tank by pulling the rubber tube of the nipple on the top of the carburettor. You may want to double the rubber fuel tube over and secure it in this position with a clothes peg. This is to stop fuel leaking out.
Remove the bottom fairing by unscrewing the holding bolts (two on each side), this frees the bottom fairing from the top. Unscrew the two bolts on the underside of the bottom fairing. The bottom fairing is now free. The top fairing is only now held on by one last bolt located in between the handle bars at the front of the mini moto.
Once you have removed the fairing, you will need to take the chain off the front sprocket. To do this loosen the back wheel nuts and the tensioning bolts. The back wheel can now be manoeuvred toward the front sprocket loosing the chain. When the chain is loose enough you can remove it from the front sprocket.
Remove the pull start from the engine by unscrewing the three holding screws. Once the pull start has been removed you will see the wire that comes from the stop switch. Unplug this.
The throttle cable can be removed from its fitting on the top of the carburettor. Pull the rubber seal up so that the locking nut can be unscrewed, the throttle can now be pulled from the carburettor along with the needle valve and spring.
The next step is to Remove the Exhaust. The exhaust is fixed to the mini motos frame by a bolt located just under the seat fairing toward the back of your mini moto. Undo this bolt with a spanner and an alan key. The exhaust is fixed to the underside of the engine by two bolts via a gasket. Remove the two bolts with an alan key making sure that you do not lose the gasket washer. The exhaust can now be slid out past the engine and removed form the mini moto.
The engine is free from its mechanical fittings, the engine then needs to be removed from the mini motos frame. The bolt at the top of the engine must be undone first using the alan key. The three screws located on the underside of the engine are the last fixings to be undone. The engine can now be completely removed from the mini moto.
