Re: Rebuild Compression

Loss of compression comes from three places: 1. Valves. Assuming you tested your valve seal before putting the head back on, check you have tappet clearance and you valves fully close. 2. Head gasket. I know you have annealed your head gasket, and assuming you checked the head and cylinder top for f...

Oh, I think (but not sure) that the later B50 style outer cover is different to the earlier ones (my 250 has the later one).

Re: TR5MX clutch/kickstart issue

The major difference is where the points wire exits, but clean up your old one first, despite the swarf it may be OK. I's investigate why it made the swarf in the first place, that nut doesn't look like it is on all the way, how much end float do you have on the mainshaft? Has the clutch fallen off?

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: 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.
