WB30 before and after...Ian

Impressive! What is the finish on the crankcase? What is the finish on the exhaust? Is there a source for the pancake air filter, either NOS or repro?

Hi John...The crankcases and other alloy castings were bead blasted using a 60-80 grade aluminium oxide grit at 90psi and then finished with a glass bead at 65psi...

The exhaust is stainless steel, again bead blasted but using just the aluminium oxide media...

The air filter is not a Vokes but a Burgess..Standard fitment for late model (1942 on) WB30s but not fitted to any other WD machine I don't think..

There is a very similar but not identical Vokes version. No filter came with the bike but I was lucky enough to find an original during the restoration...

I don't know of a replica...Ian

A fine restoration Ian........I have a few other images of B30's with the "FOM" registration marks not too far away from yours either.........

Did you have any issues with the hairpin valve springs or is yours running on coil springs ?

I wonder if any of the early alternator lighting system components survive, such as the unit itself and the headlight ? Seemingly, they were not too successful........

Mine was the later (3rd.)variant of the WB30 engine where the 'hairpins' had been replaced by plain coil springs...

Apparently problems were encountered with premature valve guide wear on the earlier versions...It wasn't a set up BSA were conversent with...the B29 and subsequent development of it, the B30 were the only BSAs ever to be thus equipped...Only a few hundred bikes in total in fact....

I don't know of any of the early alternator equipment that has survived...Some of the first 50 B30s that had the system had conventional magdynos retro fitted..

I have two period pictures of the same bike with this modification done..

'FOM' registrations were Birmingham numbers that were issued to BSA in a block and which they applied as required...Ian
