Had a shock on prices of small nylon toothed drive wheels and belts!
So, plan B in action – use the OEM [ GSXR ] chain drive sprocket system.
After getting yet ANOTHER shock for the price wanted for a chain and sprocket – I ordered another pump – complete with chain and sprocket for sub £10 delivered.
Might require a small chain guard – but relatively straightforward.
The overall plan is now firmed up in my head – sketches over the next few days [ with delays for birthday celebrations ! ]- and I’ll post up for approval / criticism / etc.
Some pix next week when there’s more parts arrived.
