Re: GPS Speedometer

I think that speedo uses a standard GPS antenna. I has something similar mounted on an old van I had, it eventually succumbed to water ingress. Knowing the size I would be tempted to try to hide it under the seat foam, so unless your arse is made of mu-metal it should perform quite well.

Re: tightening head nuts sequence

IMHO: The important ones are 1 - 4, and there are only 6 in total! I don't "Torque" them up, I pinch them all up then work round 1 - 4 nudging them up (and chase up 5 & 6) until they are tight, doing them up evenly...How tight?

Re: Little BSS cafe racer

I wouldn't put gunge anywhere near the oil pump, it is too close to the important bearings and is probably the one essential organ in the engine that needs to be right, fix it properly or get a new one (better one) or pay the price of a complete rebuild in a few miles.

Kommando has probably nailed it succinctly. Before you have an uncontrollable spanner frenzy: Double check the ignition. 1. Make sure you have the Trispark "B" version....I think this is marked on the stator somewhere. 2. Go through the timing routine again. Do not trust the marks on the alternator,...

Re: Cooked battery

Lead acid should charge about 2.275 v/cell or 13.65v for a 12v block (not accounting for temperature). Your meter is probably reading some ripple as well. New battery and check the voltage again, all should be well.

Re: flywheel balancing

As far as I understand (and I'm no expert on these matters) the knack is to ensure once balanced, that both flywheels weigh the same, whatever balance factor you use. This means you have to make sure the flywheels weigh the same before you dynamically balance the whole shaft.

This is the gearbox breather, gearbox warms up, stuff expands and it cools down, this little hole allows the pressures to equalise. I surprised you say the gearbox is venting (over full? it only takes a splash), and you say the oil is black, have you got a leak between crank and gearbox?
