Section Technical Library

Currently the format for this section has not been formalised though it proposed to include specifications, plus useful information concerning maintenance and repairs etc. Each file will open in it's own window so all that you have to do is close it and you will still be in the Technical library. If anyone has any technical information to share please let the Webmaster know. The following files are mainly PDF files and you will need Adobe reader to view them, it is free and obtainable from here.

So far there are sections of PDF files, Engine and Frame numbers, Registration numbers, How to research a reg number and finally a section on where to find some online manuals.

Spark Plugs(Champion) pre 1963 motorcycles, scooters and mopeds
Just in case your plug has been discontinued check this list, then go to the NGK partfinder and you can work through either the Motorcycle catalogue, or, if your machine is not listed and you know the code for the old Champion plug, go to the Product Cross Reference. I've worked through a number of my machines and in every case I've managed to track the modern NGK equivalent.

Registration numbers: -
Some members may well own a motorcycle not registered on the DVLA computer yet would know the registration number. It is possible to recover the original registration number under the V765 scheme, details of which can be had from the VMCC Librarian. Briefly you would need some piece of paperwork to support an application to retain the original number for your machine. Something like the old Log Book or an old tax disc would be ideal. Another option is a certified copy of the original record from the original registering authority. To find the name of the original registration authority and where it's archive now is, needs a bit of detective work. Note that not all registration authority records have been saved in an archive, so you may be unlucky.

Firstly you need to determine the authority that originally issued your registration number, that you can find here in this PDF file. There's a lot of information in the file and it has been put together in country (England, Wales, Scotland etc) order. Having found the name of the original registration authority, go to the kitheadtrust location list and you will find, hopefully, the location of the archive - then you need to contact the archive to obtain a copy of the original record, quoting registration, frame and engine numbers. I believe that some archives charge for the service, so be prepared for that. Having obtained your evidence you would then need to contact the VMCC, who are authorised by the DVLA to operate the V765 scheme - the club would then arrange for an inspection of the machine. Good luck and if you need help then contact the webmaster.

With no documentary evidence, even if you know the original reg number, you will have to apply for an age related number - a simpler procedure. Again, it's the VMCC who can provide a 'statement of search' to date the machine, details of which can be found on the main VMCC website.

Researching a registered machine: -
If the make and registration number are known then go to vehiclelicence.gov and click enquiry. You can then enter the details and the system will tell you if the vehicle is taxed, sorned or unlicensed. The later category indicates that the vehicle is known to the DVLA but that it is on the 'dormant' register. That means that you do not have to tax the machine or sorn it. Remember that as soon as you do tax the machine, it will move permanently on to the 'live' register and from then on you will either have to tax or sorn it.
One of the problems with the DVLA enquiry system is that they provide a dropdown list of known makes - fine if you are looking for a Honda, not so good if you are looking for a Clement-Garrard or a Scott. However, you can type the make in but even that doesn't always work. Quite often a machine may be listed by the DVLA with a name that is incorrect. I had a real fight with them over the make of my WWII Jeep. They originally had it listed as a Jeep, which it isn't, of course, It's a Willys-Overland model MB42. Jeep is nowadays a recognised make but it was only a nickname when my Willys was made. After many letters and wrong changes they eventually got to the make as a 'Willys-Overland MB'. You'd never find it on their search under it's proper name of 'Willys-Overland' as it is still wrongly listed. Even better is the model, instead of 'MB42' they have it listed as '2-axle-rigid body Landrover/Jeep'. I ask you!! There was no such thing as a Landrover when my Willys was made. I gave up trying to get them to correct their records at that stage. So beware the DVLA database is not always accurate and you'll be on an uphill struggle to get them to accept what you say about your machine, as I've found out.
So, if you can't find your machine on the database because of the make: -
Go to the RAC website and click on the link 'car checks and inspections'. Then go for a 'car data check' and click 'go'. Select 'buy 1 check' and key in the registration number and very basic information comes up on that registration number, including the all important vehicle maker as recorded by the DVLA. Note that there is no requirement to progress to the actual 'buying' stage, instead, just close the page. Although this refers to cars it does work for motorcycles. I had to use it for my New Hudson - the DVLA enquiry told me that it wasn't on the database, but I have a V5. Using the RAC system I found that it is listed as 'NEWHUDSON' and not 'NEW HUDSON' - the space making all the difference. Somehow I can't see myself trying to get the DVLA to put the space in.

The following websites can provide online motorcycle manuals: -

Motobecane (Mobylette etc) Manuals can be downloaded, page by page, from this site which seems to have a comprehensive set of manuals - well worth a look if you have a Mobylette or some such.

Scribd There are quite a few manuals posted on this site, especially by a contributor called Thunderbird3. They are not easy to download as the site asks you to sign in using Facebook, which is something that I would not recommend you use, or you can register directly with the site. However, they ask for money for you to be able to download the manuals. Let me know if you need any help with this as it can be by-passed.

Moped Riders Association
Ideal for those moped manuals, I downloaded my Honda P50 manual from this site.

Dans motorcycle manuals
Here's a load of links to sites that have manuals online and ready for downloading, but don't get too excited as I've found many broken links and sods law says that the link won't work for the manual that you're looking for. However, all is not lost as there is a thing called 'The Wayback Machine' towards the top of the page and I've been able to find several manuals that I wanted by using that facility - give it a go. It really is easy to use, although a bit slow in recovering the page that you want from the archive - so, if you find that a link is broken, highlight the URL(that's the bit in the search window box that starts HTTP), go to edit and click 'copy'. Then go to the wayback machine and set the mouse pointer in the search box. Then go to 'edit' and click 'paste' and the URL will appear in the box. Then click the 'take me back' button and wait with fingers crossed, it usually works.

Carl Salter motorcycle manuals
Easy to use site for various manuals - many modern ones, but worth looking through the list.
