Have a look here for as much carb information as you are likely to need.

http://www.jba.bc.ca/Bushmans%20Carb%20Tuning.html

He states that a .106 needle jet is .106Ē diameter which is the size of a number 36 drill, I can verify this having checked a new set bought last year from Amal. However not everyone has a set of number drills, so you if youíre in any doubt jets arenít that expensive so why not replace them as a matter of course.

As far as valve clearances are concerned why bother setting them tight or slack when itís just as easy  to set them correctly. I dunno if youíve come across the tip for setting them by winding them down onto the valve tip by hand and then backing them off. You will have to determine what thread pitch the adjusters are, I would guess yours are CEI, then working out how much of a turn gives you 0.004. This is a particularly good way of setting valve clearances if the valve tips are worn.

British Bikes / Re: Wheel alignment
« on: December 28, 2018, 09:01:39 AM »
Iíd agree the wheels should be in line.

Thereís not much you can do about the front wheel other than checking the offset of the rim if youíve respoked it Iíd also check this on the rear wheel. If you look closely at the rear frame loop and swinging arm you will likely find it isnít on the centre line of the frame and is offset. The quickest way to get a rough idea of whether the rear wheel is true in the swinging arm is to measure from the center of the swinging arm spindle to the centre of the wheel spindle making sure they are the same on both sides. It would be as well to check the engine sprocket is in alignment with the wheel sprocket while your at it just to make sure the spacers have gone back in the right place. If you then check the front and rear wheel alignment with string or timber as R suggests then youíll have a good idea whether anythingís amiss. Iíd ignore the markings on the adjusters and certainly wouldnít go by the tyre or rim being central in the swinging arm. Iím also assuming the frame or forks arenít bent.

The tank mounting nut and stud is 5/16UNF, part numbers 14-0302 and 83-4930. The diameter of the into head exhaust on my Ď77 Bonnie is more canal boat size at 35mm.

« on: December 06, 2018, 10:31:15 AM »
I think you have misunderstood me. I meant it had to be in a roadworthy condition i.e. if it went for an MoT it would pass. It wouldnít need an MoT because of its age. When I did my tractor I believe they could insist I took it to be examined, I did provide them with plenty of before and after photos.

Having had a quick look on here
https://www.gov.uk/vehicle-registration/old-vehicles
It would appear that if your vehicle was of an age where it wasnít MoT exempt then it would need to be MoTíd before you could get it registered.

8 views and no replies so Iíll give you my dodgy twopennorth.

The dating certificate has to be obtained from a recognised club which will probably charge unless you join. The vehicle also has to be in a condition where it would pass an MoT at the point of applying for the certificate.

The reason this could be dodgy info is because itís over five years since I obtained a registration certificate and it was for a tractor, I went to the local DVLA office and I believe they have all been closed now.

your useless painter.
Heís not useless, heís very good.

 I think for him it wasnít worth the hassle of going away from his normal supplier to find a particular colour match from a colour name that hadnít been used for over forty years. If he was to have the paint mixed where was he going to get the original colour sample from and how much had that sample faided over the years.

I did just what R has suggested and chose standard colours from his paint charts that my rose tinted glasses told me were the original ones, but more to the point were colours I liked and looked good together.

This is about the best info I found when l was researching the colours for mine though itís too previous for me and the O.P.

I had my Ď72 T120V sprayed earlier this year. The bloke who sprayed it said there wasnít a cat in hells chance of getting the original colour, mainly because of the different materials used to make paint nowadays. Iím not sure if this was a cock and bull story to make life easier for him but is seemed plausible at the time. I ended up choosing the colours from his colour charts that suited my memory of the bike from 40 years ago.

I was quoted £100 for my Bonnie grab rail to be re plated at a platers in Hull. £10 just to have it stripped if I was to have it powder coated. New ones are £80 ish, which I donít really want because I want to keep as many original parts as possible. So far itís bolted back on as it was until I make a decision.

To have two rims done Iíll raise Mini-Meís two french scrap heaps to four.

Could the tenth hole be a well made plug rather than a cast in blank. Come to think of it, for that size hole I doubt it would have been incorporated in the casting.
