Re: Oil circulation procedure

Temporary, yes, although it was still working when the bike was sold, but it would indicate where the problem lies.

Re: Oil circulation procedure

I had a similar problem with a 3HW Triumph, oil pump is similar; I packed the pump with vaseline and it worked! might be worth a try?

Re: Experience with Thorspark electronic ignition kit

I've had one on my VB for 6000 miles now, I like it, reliable starting, once I sorted the carburation, easy timing adjustment ( I set it by feel, far to much bother timing it with a degree wheel )

Re: Stripping a crankshaft

I put it on a workmate with the axle in the slot, then put a long tyre lever over the bottom flywheel with the ends clamped to the workmate with g-cramps. if you put it towards one end you can hold the workmate with your hip as you heave on the spanner.

Re: Thorspark Electronic Ignition advice.

I put a Thorspark on my VB. I just set it up approximately so that it would run, then adjusted it until it felt right when riding. I couldn't'd be bothered to strip the clutch 3 times to strobe it, but I'm happy with it after a bit of experimentation. As you say adjusting the advance /retard as you ...

Re: JP piston for a VB

I had a JP +60 thou in my 58 VB; it vibrated quite a lot, especially on tickover; I sleeved the barrel back to standard and fitted a 5631 piston I had, result - much less vibration.

Re: 1946 VB (Iron Head )valve chest oiling

Gary,
Just tried it, doesn't seem to suck or blow when revved from a fast tick over. I've a plastic tube on the breather that extends below the bottom frame tube, don't know if that affects it, certainly it's oily so must be blowing when it's revving on the road. I did the mod about 900 miles ago ...

Re: 1946 VB (Iron Head )valve chest oiling

My VB had a 5/16 in hole on the bottom of the valve chest; the thing burnt oil like it was going out of style. After new valve guides ,resleeving the barrel and a Heplex piston didn't make much difference I turned up a plug with a 2mm hole for it; oil burning ( and smoking ) doesn't happen any more ...
