This set up is correct the cable inner wire pear nipples hooks into the bracket on the frame then when the pedal is depressed the lever on the brake pedal shaft moves rearward pushing the outer toward the back of the bike.
Because the outer is anchored on the brake plate this movement transfers to a pull of the inner cable which applies the brake.
When the bike was new both hubs had a chrome braking surface but with time the chrome finish sometimes came away. The fix was and is still to machine in a metal liner often cast iron but sometimes stainless steel which has a surface like you describe.
Wezzo in my Cub chain case I put sufficient tqf to cover the primary chain, I keep to hand a piece of wire bent to form a dipstick because you cannot see how much is in there.
The engine is a Villiers Starmaker contact Villiers Services here in the UK for all you need.
Frame is a DOT which would have had DOT leading link forks fitted when new, the forks currently fitted could be MP Metal Profiles.
Uncertain about the wheels earlier DOT bikes had pressed steel British Hub Company 40 spoke hubs, then later usually on the square tube framed bikes Grimeca alloy full width hubs which were 36 spoke.
The filter is usually fitted into the return line on a classic bike to prevent oil starvation, think it's all explained on some of the filter websites.
Any of the above filters would be perfect for your bike.
For the oil tank I would make from alloy, pick up pipe needs to be from the base of the tank with return into the top where it can be seen to be working.
I think it likely to be a blocked pilot jet, it could be as simple as the fuel has evaporated leaving the oil behind.
Best to find a diagram of the carb then dismantle that from your bike check all gaskets and O rings and blow it clean through all the drillings using compressed air, careful with the float and notice the needle position is back where you found it. Check and clean the air filter as well.
Worrying news Alberto. I have just heard that France is closing down all but essential services and talk of restrictions here from early next week. No words to describe the situation.
Electronic ignition or maybe a new carb if either is needed, if the footrests are worn out and hanging down then replace them other than that keep it has it is and enjoy riding it.
Why ruin it with unnecessary alterations, you needlessly mention Pre65 while in the same post ask about modyfing a twinshock.
Can anyone explain how the Ferrari team have made it to Melbourne for the Australian GP when Italian teams and iders could not attend the previuos weeks MotoGP?
See attached picture showing all of the ratios, the swapped second gear can be used in sections ok depending on your sprocket sizes and rider weight . The best thing about the low second gear kit is the higher top gear!
Hope the spread sheet makes sense
Thanks for the spreadsheet ikb very interesting and Paulmac for the set up you have.
It would be interesting to know who first realised that the Bantam gears could be interchanged to give alternate ratios. I read that one major reason why BSA did not produce a trials version of the Bantam was because of the high cost of manufacturing gear clusters as used on the works bike's, yet surely BSA must have known that this could be achieved using the part's they already had.
Is it a good idea to swap around the existing 2nd and 3rd gears, I found a diagram of how to do this on the web but if that lowers second then what happens to third gear. Is it instead better to buy the aftermarket second gear set which is I believe 20/27 ?
Which ignition system and crankshaft weight is the one to get
All BSA Bantam engine build hints and tips welcomed
Thanks trialsrfun it was a hard trials so was v happy with the result. The no gloves is only because i felt over in the river earlier on. This is the bike in question below
You are very welcome, congratulations on your winning ride
Some ride indeed. I'm not familiar with this particular bike, presumably it's not tricked out much, as so many "pre 65ers"are?

No this is an alloy beam frame Villiers engine model
Does anyone know if there a source for new crankshafts for Villiers 9e or 32a engines?
I'm looking to convert an 11e engine, which has the extra bearing on the right hand side and the longer crankshaft. The plan is to remove the additional bearing (and casing) and to fit the narrower crank. I had seen full circle crankshafts for sale on-line, but they now appear to be out of stock.
I'm happy to consider fitting a hammer head crank, but the trend (and the maths) would suggest moving to the full circle version if it were available.
Alternatively, is there a modern 2-stroke crank that can be modified to fit the Villiers cases? Before anyone screams about using modern internals in a pre '65 bike, this will be ridden in local novice and sportsman events where everyone else will be riding mono shocks.
