Re: My 46 SQ4 is finished - or so I thought

John, I was lucky, the flange on mine had been repaired previously with an aluminium insert threaded into the timing case. I simple found an oilseal of the right diameter to screw into the existing thread. Whether this will work in practice remains to be seen. thread.jpg If you are going to the effo...

Re: My 46 SQ4 is finished - or so I thought

John, The flange itself is only part of the oil seal mechanism. The inside diameter of the flange hole is such as to give a relatively close clearance with the magneto sprocket. You should find that there is an external thread on the back of your magneto sprocket. As the engine rotates this thread c...

I'll have a look through my other build pictures to see if I can find any pictures from different angles.

Re: Wheel rim alignment for for later tele forks

Paul, The fork stanchions on the 1946-48 forks are positioned closer together than on the 1949-onward forks. This requires a longer front spindle, amongst other changes. Without a set of early yokes to compare, I can't be certain what the difference in spacing is, but I think it is either 1/8" ...

Re: 1949 telescopic forks black or chrome?

Thanks Simon - I was sure someone would know the definitive answer.

Black and black it is then. That's easy, I can do black paint but what shade of black paint should I use?

Wheel rim alignment for for later tele forks

I have fitted a set of "short-eared" forks to my 1949 VH500 which I believe to be correct for the year however, when I fit the wheel (which was laced correctly for the earlier narrower forks), the wheel does not now sit centrally between the forks. Do I need to adjust the wheel lacing to f...

1949 telescopic forks black or chrome?

Anorak help please. Should a 1949 VH500 have black or chrome fork oilseal holders? I need to replace the oilseals and I have got both chrome and black holders available so, while I am doing the job, I might as well use the correct type. Looking at pictures on the internet most people seem to use chr...

NH chain alignment - bent frame

Thank you for the pictures Alan - this is just the information I needed to eliminate the issue being with the gearbox. Unfortunately the bad news is that I am now fairly sure I have identified the real problem. When I checked the rear sprocket alignment relative to the chainline it was significantly...
