Re: Kneegrip threads

Thanks for the info Paul,

Shame they didn't bother to use a 5/16" cycle thread rather than UNF but I guess I can live with it.

Kneegrip threads

Last year I bought a '49 single that came with a spare petrol tank that I think is from a prewar 350 but I don't really know. My question is about the knee grip fixings. 350 tank.jpg The front holes are threaded 1/4" 26 tpi (which I would expect) but rear have studs with what appears to be 5/16...

Re: Expensive Solex carb

Paul

One thing I forgot to mention is to make sure that, when you put the plate back on, the two little notches on the edge of the other plate face towards the big cut-away hole in the valve plate (see right hand picture). I say this from personal experience of doing it wrong the first time.

Re: Expensive Solex carb

The solex I have is not from a Square 4 and the choke works in reverse (pull it out to turn the choke off).

Re: Single frame dimensions

Thats nothing ...I reckon hand pressure would line the holes up. John - You forget that you are talking to a pommie wimp here. I ended up using a threaded puller between the top sidecar lug and the engine plates with a load cell in it. It took just over 70 kgf to pull the holes into alignment and a...

Re: Seat/Mudguard Lug on Anstey Frame

Paul

Are you saying that this type of lug was used on later KH frames? Was it for machines fitted with dual seats?

Re: Single frame dimensions

I've got a podger bar however the offset is bit more than I would be happy with just podging into place.

I am going to set up a jig to pull it a bit closer into line.

Re: Single frame dimensions

Paul I'm pretty sure it's a single frame. The problem is that the distance between the front lugs is too big not too small - a tad over 9" (8-9/16 in the diagram). In addition the horizonal distance between the top front and top rear lugs is about 15-1/2" (15-1/32 in the diagram). I was ho...

Single frame dimensions

The engine plate holes don't line up with my frame lugs so I think some fettling is in order. I found this diagram on the web but I am not clear on a couple of dimensions: Ariel, Spring, Single and Twin, 1947-53 1a.jpg 1) What is this dimension A for a single? Is it the same as that for the twin? 2)...

Re: Seat/Mudguard Lug on Anstey Frame

That blue and black looks familiar - don't suppose the frame came from Pete K. ??
