Where can I get this rocker cover stud? What size thread?

[nidyanazo]

Here is the one I'm talking about:
On the intake side.

Can I get this at a good hardware store? What type of threads is it?
Or where do you recommend?
The head is back from having a clean up. New valves, seals, guides, decarbonized etc. The works.
But I'm missing the one stud here!!
Darn!

Thanks guys!

Norvil Motorcycles have them in their catalogue under part number 067693 for just over 50 pence.

It is most likely cycle thread (26 TPI) Many parts on British bikes are cycle threads whatever the diameter. I am presently working on modifying the internals of the front forks and all the parts I am making are 26 TPI.

I'd like to know what you have cooking up with those forks :wink: .

It's different thread at both ends....Cycle at the nut end and WW at the head end if I remember correctly!

I can't see the picture here at work (blocked), but if it is the intake valve cover stud it is 5/16 diameter with 22 tpi at one end and 26 tpi at the other.

It will either have to be turned up on a lathe or your closest option is probably to order one from Fred at Old Britts. He shows 5 in stock. $1.54.

Me too! Be sure to take notes ....please. I had to replace a fork leg so now it's apart and I'm thinking ... what can I do that won't cost me an arm and a leg? I'm looking at reusing everything that's in there already but maybe plugging and drilling some holes and using longer bushings and $pringing for some variable rate springs.

Here's some food for thought!

Old Britt's website shows it available for $1.54. Looks like it's a 5/16 diameter with 26 at one end and 22 at the other:

NM18033 Stud, Rear Rocker Cover, 5/16x26x22

Good Luck

Went back to the machine shop....He had it there.

Thanks everyone!

Interesting, but like it says in the text, "no rebound damping" I will write up what I have been working on (with major help from Greg aka norbsa) today or tomorrow.

Although many people have inquired about using my kits on an Atlas I could never get anyone to take the critical measurements on their Atlas. I have N-15's and Commandos but no Atlas. So many people had asked I had a form letter saved. Than about the tenth person came along in the form of Jean. I needed a person not afraid to take their front end apart and put it together many times. I am so glad Jean hurt his shoulder hope it's better now Jean. Well after a week or so of emails we worked it out. Jean is a hard working and clever fellow. Many thanks to him. I will let him write up his own findings the real test is to ride it. There is a bit of work to get it were one can try. Greg

Greg,

I would have done it with a good shoulder ;-) I don't mind experimenting, the pain and temporary disability I could do without.
