No danger of wheelie with 2 BSA drums up front

The thread should be long enough to start the nut without it contacting the spring. Forget the tab washer and use loctite

The timed breather on the camshaft is designed to keep the crankcase at below atmospheric pressure. Adding a breather to the rockerbox destroys this

Singles / Re: BSA B33 Engine Oil Gauge mounting

There is very little oil pressure on a B33, probably won't even register on a gauge. It is a Roller bearing engine so its oil flow rate that matters

Anything fitted between the tank and pump can cause engine damage, gear pumps are good at pumping but not so good at sucking

Your slots are not that badly worn compared to most.
Fit the wider Gold Star mag straps, they hold the mag more securely

I didn't bother with either the BSA on my timing cover (hidden behind the pipe) or the piled arms on the pushrod tunnel (looks classier left un painted)

The best solution is to replace the rims with alloy or stainless rims and stainless spokes

I would say even if it was possible it would be undesirable. The compression ratio would be high and the valve sizes smaller than the B33

The inner drum, basket and pressure plate are Suzuki GS850 shortened by one plate. The sprocket is a standard plate sprocket fitted with a ball race onto a modified BSA centre. A modified rusty old BSA inner drum unites the Suzuki drum to BSA centre

Probably just preloading up old saggy springs

it would be folly not to put a new rod and big end in it while it's apart. A leg out of bed can be expensive
