Hello Thomas,

The ‘Blue Oil’ is most likely Millers Oils Classic CM2T this is a 2 stroke mineral SAE40 oil, designed for vintage and classic 2 stoke engines.

I use and recommend this for engines I rebuild. 50:1 in the petrol and drips to the mains either through dripper or a Pilgrim.

It is not correct to say the oil runs through by gravity. It is sucked in by the piston on its up stroke. There is a gland behind the crank that closes off the oil feed on the downstroke.

best wishes to all for 2017
regards
Eddie

Hi Eric,
This type of mechanism has indeed been around for a long time. It dramatically reduces the force required to lift the clutch as it makes use of the reaction force of the cable outer that is lost on the gearbox case in the standard mechanism. I produce the mechanism shown below, this is to a design drawn up by Roger Moss. He has used this on his racer for many years.
It is not a direct fit, as there are some small modifications required to the back of the case, requiring the case to be out of the bike. The standard bronze quick thread release is very prone to wear, being open to any road grit. This improved type overcomes that problem also.

Hello Roger
The purpose of these springs is to centralise the footchange lever after each gearchange.
The band is a push fit over the central hub and can be pressed off, it is a little more difficult to get it back on requiring the two springs to be held in place with a jubilee clip as it is pressed back on.
If you find the springs are worn I have new ones as does the spares scheme.
The pins should not affect the operation if worn. The short one held in the centre boss is merely there to hold apart the spring ends so the whole unit can be assembled onto the backplate.
Hope this helps
Eddie

Hi Derek,

Glad to hear that you are riding your Scott enthusiastically this is exactly what they were made for.
Later gearboxes have an oil seal fitted to the clutch end of the box as this was recognized as a problem, however, the felt seal rings inside the clutch nut were retained and these quickly become soaked and less than efficient. The felt seal can easily be replaced with an off the shelf modern seal, in order to fit a seal to the high gear behind the clutch then the gearbox has to be machined to shorten the bronze bush and boss. This obviously means a complete strip down. The kickstart end never had a seal and various attempts have been made in the past to help here usually by trapping an O ring behind the kick start ratchet. If you are having excessive oil loss here it probably indicates a worn bronze bush as this is not usually a big problem. An oil seal can be fitted but it does mean machining a pocket into the hardened end of the Kick start boss, again meaning a complete strip down. In order to solve this problem many owners have resorted to grease filled boxes, I would not be happy with this solution personally, especially if ridding hard.

Great to hear that progress is being made with the website.
I would agree with the suggestions made regarding history, photos, and links.
With regards to all the other issues, this is a rather one sided conversation of course as the only people taking part will be those logged in. Which I am guessing does not represent the vast majority of members.
There has been much talk over many years about the forum, should it be open to all or just members. I am sure that Paul would confirm that spam is a real problem and takes up much of the webmasters time. Whilst I agree with the idea of an open forum, I think we must be realistic and accept that if we are going to move forward with a professional site we have to accept the advice of those putting it together and operating it for us. Links in the open section to Technicalities and Rogers newsletter plus extensive information about models etc together with the modern attractive look of the site should be plenty to attract the new member.
Perhaps it would be an idea to have a two tier membership system (sorry Richard) with members who pay a reduced fee able to access the site but do not receive the magazine. Magazines archived on the site would then need to be at least a year behind if not two.

Try Alan Noakes, his details are in the back of Yowl. He makes new alloy thrust plates.

Send the basket to Saftek they will bond friction disc on for you at resonable rates with a quick turn around.

During the the last ten years of refurbishing gearboxes I have had two requests for close ratio upgrades. It is understandable therefore that David is reluctant to accommodate requests for same. The main problem is not the 26T gear but the built up layshaft as many owners wishing to upgrade will have a solid layshaft.
I can send you a copy of the original works drawing for the 26T gear if you wish or if there is enough interest I could investigate manufacture on behalf of the club although I suspect this could be expensive.

Hi Steve
The nut screws into the inner stanchion are you holding the bottom of the fork leg to stop it turning?

Adjustment of the short connecting link between footchange and gearbox is critical and tricky. With the gearbox cover removed you should check that on selecting second gear the dogs slide correctly into alignment and the ball on the detent arm drops into the pocket on the plate. The detent plate is held in place by two short 1/4 BSW screws and these can come loose leaving inaccurate detent positioning.
If all correct, I would suspect worn dogs.
