What do I need to do, prior to getting my Armac front frame?
We weld a new engine mount to the gearbox, remove the bottom engine mount and countersink the oil union. We need your centre crankcase and oil union to do this; you can bring it to the workshop, where Duncan will do the work while you wait, or you can post it. If you prefer to do the work yourself, we can provide full instructions.
Do I need to strip the engine?
It’s easier to do the mods with just the crankcase, but it is also possible to do it with the engine intact, provided you remove the ignition and drain the oil.
How much oil do I put in the Armac frame?
Capacity is 750ml, but put in 600ml. We use PJ1 Fully Synthetic
Which rear shocks do you recommend?
Length: 13.5 inches / 340-350mm. Shock mounts on the swinging arm: 12mm diameter.

What forks do you recommend?
