"Or, buy a universal cable to work out the lengths from, then get the cable made by JJ cables or the like" Yes, that's what I am going to have to do

The problem for me is that I can't solder. John what are the dimensions? I could get one made if I knew that

Does anyone know if the BSA A10 s/s 8" brake cable is the same size as for the Eddie Dow Duetto twin leading shoe brake?

Don't know if it's still available, but Hughie Hanncox did a DVD on rebuilding Triumph unit twins. it might even be available through the local library to order

I'm glad the problem is resolved. Lamps in long term storage are unfortunately prone to leaks. In the days when I was involved in lamp making all lamps were put into a 7 hold before being tested as an insurance against capillary leakage. It is also worth knowing that frequent use of the headlamp flasher will cause halogen lamps to fail because the lamp is not lit long enough for the tungsten filament cycle to reach operating temperature.

May I ask, from where did you source your lamps? I worked in the lighting industry for many years, and the symptoms you describe are associated with air inside the glass. Going cloudy accompanied by rapid failure is a sign that either the seal is compromised by a capillary leak or that during the manufacturing process the lamp was not flushed properly to purge out the air leaving the fill gas contaminated. The presence of air will cause the filament material to quickly evaporate due to excessive heat. All incandescent lamps are normally filled with argon to inhibit this process a few others are vacuum lamps. Halogen lamps work in a similar same way the main difference being when the lamp reaches operating temperature the filament evaporation particles are recycled back to the filament. Internal clouding is indicative of air contamination.

British Bikes / Re: Fitting Britax rear crash bars

That's an interesting idea, but my bike is an S/A frame and has no sidecar mounting lugs and the taper is at the opposite end anyway. It is designed to replace the folding rear foot rests, and as you can see the footrest is machined to allow for silencer clearance. The search for a solution continues.....! There must be an adapter of some kind I would have thought which is missing. Always a problem when buying used items. Anyway you can see from the picture how the footrest is connected to the frame. It's how the footrest connects to the actual crash bar that is proving to be problematic. The Britax bars are of course designed to be universal one fits all accessory. The genuine BSA item is unobtainium.

I want to fit a set of Britax rear crash bars to my A10. Can anyone tell me what is the purpose of the bevel on the footrest? It doesn't match the crash bar fixing point in anyway that I can see. I have scoured the internet unsuccessfully looking for Britax fitting instructions. any help or suggestions would be greatly appreciated.second picture is where footrest is supposed to attach to the crash bar

After a lot of searching (years) I have found me a pair of Britax rear crash bars. Has anyone got or know of a source for fitting instructions?  Looking at them it doesn't appear to be to difficult, but one immediate snag I can see is that the top anchorage bracket is to thick to fit between the mudguard cotton reel spacer and the frame. If the spacer is left out then the anchorage bracket is not wide enough. Has anyone fitted Britax rear crash bars, and if you did how did you do it?

Ian, no I have never heard of a mag seizing either, but I am worried by the fact that repro fibre gears have an iffy reputation in some quarters.

Just removed the magneto from my A10 to have it refurbished. I noticed one of the fibre gear teeth was chipped so I'm seeking advice. Go with a new fibre gear or opt for an ally one. I'm leaning towards ally because fibre gear failure appears to be a relatively common occurance. Personal experiences anyone?

That's what I have. Dexron ( Halfords universal actually ) Just to complicate matters there are differing types of Dexron I have discovered. 2, 3, and 4

I just remembered, not all ATF's are suitable,  You need type "F"
John, It seems the difference between "F" type and the others is the absence of friction modifiers. F type is now very difficult to find. It might be possible to find it on the internet but nobody sells it locally, not even Halfords. Apparently it is only used in Fords over 40 years old.

Thanks for your contributions. Today I double checked everything the gearbox push rod lever is parallel when the clutch lever is operated and there is about 1/8" play at the lever with the clutch engaged. I shall refit the cover and do a road test and see what happens.
