Ducati Darmah SS by Simon

12/12/2013

The Darmah was acquired in a sorry state about five years ago. When stripped for powder coating it was discovered that the magnesium wheels had rotted to the point that you could put your fingers through them. New hubs for a spoked wheel conversion cost more than the bike but really made a difference to its looks. The motor required some special tools to be made and a lot of patience to allow disassembly without breaking the cylinder head and barrels due to corrosion on head studs and exhaust rings. The front cylinder’s big end was found to be worn and was fitted with a new crank pin (this time with the oil ways lined up) and new bearings, whilst the rods were annealed, machined, fitted with ‘repair’ sleeves, bored, heat treated and honed. Quite a job. The bores were found to have only about 1.5 thou wear in them and for the time being have been left alone.

A new ‘Japanese type’ wiring loom was designed and fitted together with a modern regulator unit with the switch gear internally modified and re-wired as required (reducing the bike’s weight by about a ton!). Now we have reliable electrics.  A hydraulic clutch conversion was sourced in the U.S.A. and a nice new pair of Mikuni VM carburettors were fitted. The final touch was a truly stunning paint job by local masters Image Design.

The motor now runs a treat and the bike sounds like nothing else……………so Simon’s neighbours say.
