This is a high quality facsimile of a very rare publication - the Maintenance Instructions for Touring and Speed Models from 1925, and it goes alongside our Spare Parts List from the same year - providing useful information for anyone owning or restoring a Flat Tank Norton.
We print these pre-war catalogs in larger format making them easier to read than the original A5 format - therefore A4 format makes this catalog ures much easier to see. All else as per original - see detail information for more information.
This facsimile has been faithfully coped from a genuine 1925 maintenance manual - and this (like the corresponding 1925 Norton Spare Parts List - Item 1150) is the only copy of this rare manual I have ever seen - a rare survivor from a bygone age.
This maintenance manual is 32 pages long. I will admit, it does not have many pictures - being mostly text information, but it does make very interstting reading, and is very much geared to a very different age of motorcycle ownership where regular engine stripdowns and de-coking were a standard part of motorcycle ownership. Much of the information is still pertinent today though, and is useful for getting a good feel for what is required to run a 'Flat Tank' Norton.
There is also a period and interesting to read chapeter, written by the great Norton Wizard of Speed - D. Rl O'Donovan, entitled 'Hints on Tips on Racing Engines' As the chapter heading suggests - this section gives some useful tips on tuning Norton engines of that era - including original spark plug types and reference to both the flat tank TT, BRS and BS models.
The maintenance catalog does also include valve timing and ignition timing details - but as may be expected of such an early publication - these are mainly shown in fractions of an inch!
Altogether an interesting read, and re-produced on high quality A4 format, which makes is more easily readable than the original A5 format.
Final point - if wishing to buy this publication alongside the 1925 Spare Parts List (1150), we offer them both together as Item 1152, with a slight discount.
