Hello, I has returned to this forum just I has returned to the restore work.
I have a nice, and complete R66 1941, only 39 units builted, It's the first with oil pump to send the oil to the valves...looks like others R66, but it have one external oil return fine duct.

It's running perfectly, but I have one valve sring broked and in the list it don't appears.

Any good old bikes friend coud give me advice abouto to find or the mesures needed to built it?

Thanks a lot, from Chile

Dear Mr.R66 man,

I rebuilt a 1939 R66 with the rocker box drain tubes many years ago. It was a lovely bike and is still being ridden in the UK.

Both cylinder heads required extensive rebuilding, but replacement valve springs were acquired from R5/ R51 stock. Search all European Classic BMW spares suppliers, particularly Mark Huggett. Replacement springs shouldn't be too hard to source.

Good luck,

Gerry

Gerry: Thanks a lot, I will try again.
Best regards.
