Jubilee +40 piston set needed

Thanks but I forgot to mention that I asked Russell Motors about pistons when I ordered camshaft bushes from them.

They said they sold most of their stock to NOC!

I never considered re-sleeving the barrels. Good idea. I'll price that up against some good second hand barrels.

Interesting. However, I am going down the cylinder liner route and may have a source. I'll post a reply when I have some news.

Well what a journey! Russell Motors thought they had some new old stock barrels but I had to wait a while for them to confirm. They have some but unfortunately they could not confirm that they were correct and wanted a tidy sum.

Getting a bit creative, I have purchased standard pistons from the NOC shop, a new left hand barrel and a cylinder liner. A company in Cambridge, Meridian Engine Services, assure me that they can reline my right hand barrel.

If the plan comes together, I should be OK.

I'll let you know how I get on.

On a different topic, for attaching a timing disc, the repair manual glibly suggests using a four inch long half-inch BSF bolt. Well I did not have one 'lying around' so I bought some threaded bar on-line. What a monster half-inch BSF is!

LOL!

Hope for mine yet.

From the Norton Repair Manual 1960-68, page 34:

"To check the ignition timing .

Have available:-

A timing disc 022011

A stud 1/2 BSF 4" long and two nuts for the stud."

Nice, but I needed +40 oversize and I could not find them so I am going back to standard (no oversize) by using the only new barrel I could find and re-sleeving the other. At least that is the plan.

Is your manual for the Jubilee/Navigator - the years seem a bit odd ?

The one I have is by Norton Motors Ltd and is titled Maintenance Manual & Instruction Book for the unapproachable Norton Jubilee 250, 1959 - 63 & Navigator, 1961-63. Publication 105.

Price: Three Shillings and Six Pence.

I got the repair manual for 'Norton Twins' as a free pdf download (I couldn't afford "three and six" ). It might even have been from the NOC site, I can't remember. It has proved quite good so far for the engine but lacks details on tin ware and body work in general, hence many of my questions on the message board.
