i'm liking what youre doing Ontic. I know where you're coming from with the assymetric thing- it involves bending your mind a bit.
I'm doing kinda similar stuff to mine however with advice from those with much more experience submitted the final drive & gearbox to experienced mechs.
As far as the motobins order - any plastic bungs missing? A spare set of final drive screws definitely, rubber gaiters for final drive, spare crush washers, spare final drive & gearbox output seals?
