I was thinking of compiling a list of all the "impossible" to find new repro parts  for the 101.

For starters,

Right hand crankcase.               

Left hand crankcase

Frame lugs

Timing gear cover

Bevel gear/clutch housing

Bevel gear/clutch cover

Gearbox casting

Gearbox lid/gearchange tower

Clutch basket/bevel gear

Primary bevel drive gear

Intermediate bevel gear

Crankcase oil pump

Cylinder front and rear

There are several more.

If several owners showed interest , a batch of certain components could be produced.

For example I have used a company here in the UK who manufacture gears of all types and on gears that I have got from them I have been very pleased ith results.

The castings could perhaps be made in hiduminium in place of the usual alloy ?

This could make for a stronger component, but on the other hand could cause problems.

I would be interested to hear other owners comments.

Mike.
