Flywheel nut: Series 1-3, 4-pole flywheels

Flywheel nut suitable for early Series 1-2 4 pole flywheels. There are three different types of flywheel nuts for Lambretta Series 1-3, DL/GP so it is important to have the correct one for your particular flywheel.

Things I've noticed about this thing, By Jon: 

I check every single one of these flywheel nuts before I send them out to make sure they thread onto a crankshaft easily. If they don't go onto your crankshaft with little to no effort something is wrong with your crankshaft, check the threads and repair as needed. Get a metric thread file, I use mine almost daily. Don't forget these are reverse thread and can be difficult and expensive to repair, usually you will have to replace the crankshaft if the threads are not up to the job. Thread size, M12x1.00 LH
