Re: Rear brake lock-up

OK, That is interesting! Yes, it is downward pointing. I wonder why changing to upward pointing works?

Rear brake lock-up

Hi,

Has anyone a fix for the self locking rear brake on my '53 VB plunger? I can apply the brake quite hard and it's fine but then other times a touch on the brake pedal to scrub off a little speed and the whole shebang locks and the lever is sucked from under my foot. Quite scary! I have tried ...

Re: VB600 compression

I did wonder about the head gasket but it is a brand new solid copper one and was well anealled. I did re-torque the head after the first run out (25 ft/lb). I'll give it another run as soon as I can and see if it does it again.

VB600 compression

I've now got about 75 shakedown miles on the clock of my newly completed VB and it seems to be settling down well.

A couple of things I've noticed which intrigue me are the very high compression when cold and a small amount of oil from the head gasket. There may be a connection between these ...

Re: Leaky chaincase

Yes, admittedly the oiler caught me out initially and I was so disappointed by the lack of improvement when I blocked it off!

Re: Leaky chaincase

I've just removed the level plug and nothing comes from there. I've looked again at through the big plug and the oil is barely touching the bottom of the chain.

I'm starting to wonder if it is coming from the output side of the gearbox?

I'll run it without oil in the chaincase for a short while ...

Leaky chaincase

Just getting the shakedown runs done on my recently restored 1953 VB600 .

I'm a bit alarmed by the amount of oil that comes out of the clutch cover on the primary chain case after the engine has been run. The oil level is barely touching the primary chain.

Is this normal for the VB?
