Is it true, the 961-cranks are welded?
They don't have all of the prototypes...BritTwit said:Before Dreer decided to introduce the 961 with a 270 degree crank, all of his prototypes were 360 degree units.
Norton UK must have all of Dreer's prototypes, and original engineering data.
Maybe the new 650 twin that Norton intend to build will be a classic 360 unit.

I mean once the oil leaves the oil pump it runs through galleries and how is it introduced to the crankshaft and rods ? Also it seems to me the hollow push rods carry the oil to the top end after they pressurize the lifters . The camshaft seems to be in a cavity all alone , there must be drain back channels somewhere ? I would like to have a few hours with that spare engine of yours to help explain how this engine is oiled . How much of the oiling is just plain old fashioned splash ? The service manual really has no explanation of this. Thanks for your help. Tony
