That's standard road 2nd gear quoted there Jon, you should have 20 / 26 (same as original wide ratio)

Venhill will make cables to your pattern, if required. Last week I sent them a clutch cable, and a throttle cable- admittedly it consisted of two parts because I use a device part way along to alter the ratio, but I was a bit surprised to get a call asking for a payment of £116. Think I will stick to making my own.

Had a look around the Norton today Spen, very nice.

Is Paul Rogers riding the Norton, Spen?

Spen I used to go in to Andy Bones quite a bit in 1972, and they were well into racing then. They had a 50cc Itom at that time, but I remember they were doing a race kit for that Garelli engine in yours, consisting of a big alloy barrel, piston and head, and an expansion chamber which Ray Pettet made for them.

I've got some of Alan Whitton's hubs, and they take standard, not oversize cub shoes.

https://www.bonhams.com/auctions/21897/lot/274/ Looked pretty much as it does now, although this time the buyer gets a photocopy of James May's autograph as well.

Its either one i owned or one which has been repaired in exactly the same way. The frame broke at the headstock and the extra gusset was put in on the front down tube to strengthen it. Its also got some work done above the footrests.

He has edited his first post in this thread - i suspect that he may surface on a Cricket forum somewhere quite soon.

You can get some information here- www.howmanyleft.co.uk But obviously only bikes which are registered for the road

Keith, theres a ring of hardened steel balls which go in the sleeve gear. Hold them in place with grease,or some chain lube that has been sprayed in to the lid and stood for a bit.

Try a search on e bay for- "front fork seals 32". Some of the listings of fork seal kits have an application list of what forks they fit.

Its Inoue Rubber Co, no connection with Indian Rubber.

Cant help myself macdee, But maybe someone will see this and post a pic for you.

Hi Macdee, Early frames were prone to cracking where the box section meets the headstock. This was addressed on later frames with a reinforcing plate brazed over the last 50 mm or so of the box, up to the headstock. Around the same time, the swinging arm support plates on the frame were thickened up as they were very thin on the early ones. The Renold 531 sticker on the swinging arm when the bikes were new related to just the swinging arm, and not the main frame. It might be best to see a later frame to see what was done.

What are you on about ?

No, i wouldnt be interested.There is an event for modified bikes most weekends and quite local for me. Unless the classes you propose were to spring up all over the place i imagine the mileage involved would be prohibitive for some. I dont object to a class in principle, and i'm sure some organisers would consider an additional route if there were enough entrants to make it worthwhile.

So if an original 1955 AJS and an original 1964 AJS are in the same class, where does the "competing on equal terms" bit come in to it ? What year is yours?

Great name, sorry to have mentioned it

I agree, i suspect that nobody has told the spaniard that vertigo is an illness, associated with nausea, vomiting and the inability to balance.

No, they do a range in Aluminium rather than mazak and include a 20mm one, which is smaller than the previous smallest of 22mm. They are of the premier design. 12 ounces lighter apparently, but it would be nice if they didnt wear as quick.

I dont think its a problem on the concentric Dave, so i've not heard of anyone trying it. Dont try a 2 stroke jet on a four stroke though, as they are different other than the lack of bleed holes. Have you seen the new aluminium concentric? They do it in a 20mm too.

The mod referred to applied to the Monobloc. It involved blocking the bleed holes in the needle jet. It helps the engine to pick up cleanly at the end of a long or steep descent. Ariel HT's and genuine AMC Trials bikes had this done as standard, and this is why the original carb of, say, the HT, a Monobloc 375/64T, has the T suffix. The T means no bleed holes.

Tim The 928 (28mm) is the smallest available in the 900 series. Below that it is the 600 series and you have a choice of 20,22,24,26 and 27mm. 900 series carbs are physically bigger than the 600s', and the general trend is to use the 600,sometimes in smaller sizes than originally fitted. Hope this helps,and as said previously maybe one of the regular riders will be along to tell you what they use

The carburettor appears to be a 900 series, if it is, its too big. I would try something like a 624, or whatever the AMC riders on here are using, together with a slow action throttle.
