Re: Charging issue with 58 Huntmaster

Nick,

Digital multimeters are not very good at measuring dynamo voltage because of all the electrical noise they generate. You might get a more usable reading using an old fashioned analogue moving-coil meter.

Type 6 carburettor needle jet sizes

My iron VH is fitted with an Amal 89 carb and has run a tad rich mid-thottle since I got it back on the road so I am trying to sort out the carburation. The needle is right down to the top notch and it is still a bit lumpy so I checked the needle jet and found it was 107 rather than the standard 106...

Re: VB rear upper chain guard

...what the black slot headed screws at the bottom end does? Nothing - It fills a hole that had been drilled in the chainguard where it had been bodge by a previous owner to fit a different stay. ...your mud guard doesn't appear to have a removable or hinged rear portion to allow the wheel to be ea...

Re: VB rear upper chain guard

This picture is a 1949 rigid with a different mudguard but the stay is the same as a '46. The threaded hole (1/4" 26 tpi) on the top of the chainguard bolts to a small bracket on the inside of the stay.

Re: 4G Engine Shock Absorber Spring Plate.

I believe that the pre-war 4G spring plate should engage with the crankshaft splines when the nuts are done up and is therefore not free to rotate. 4G shock absorber 1.JPG This seems like a much better idea than the later ones which can rotate and allow the nut to wind off resulting in damaged chain...

Re: Ariel singles sludge traps

I am no expert and will likely be corrected by the more knowledgeable but, looking at the spares book, the first year to list an oil purifier was 1931. The cupped plug was part 1077-31 and a centre tube 1075-31. There is a different plug listed for 1933 onwards namely 1077-33 along with the same cen...

Re: First quick ride on the KH

The filter used on the Drags inline base is a Champion COF103101S or equivalent.

Re: First quick ride on the KH

I think you are reading the instructions for the rigid frame, the spring frame wheel removal instructions are probably under the spring frame section later in the manual. KH500 1a.jpg Release the nuts (A) on the L-shaped mudguard stays and loosen the nuts (B) on the mudguard bridge stay (just behind...

Re: VH crankcase joint

Check that the cases are indeed matching. If you look at the bottom of the cases, on one of the ribs for the crankcase bolts, one side or other of the sump plate, are stamped numbers. These are about 1/8" high and are the same on each crankcase half if they match. The numbers are the same on b...

VH crankcase joint

I have a pair of crankcases for my 52 VH project but there is a long section of the lip on the crankcase mating joint missing. crankcase joint.jpg I find that, with the crankcase bolts hand tight, the two cases can slide sideways relative to one another. Will this be a problem for the crankshaft mai...
