  1. 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.
  2. 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.
  3. I fitted this http://www.upbuk.co.uk/shop/clutch/100-4-plate-evo-clutch.html to my Cub along with the alloy pressure plate and it works well
  4. 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. You need enough spring pressure to prevent slip.
  5. Online pre event entries with a maximum number of riders would seem to me the most responsible way forward at least in the short term.
  6. 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. https://www.bing.com/images/search?view=detailV2&id=1AECF324898D4A4997662D6A96C460A958C0B0FA&thid=OIP.2GaDQ1durw9lLnBEulx_TAHaE5&mediaurl=https%3A%2F%2Fimg2.thejournal.ie%2Finline%2F4256348%2Foriginal%2F%3Fwidth%3D630%26version%3D4256348&exph=417&expw=630&q=dot+scrambles+motorcycle&selectedindex=13&ajaxhist=0&vt=0&eim=1,2,6
  7. This is the place to go to https://villiersservices.co.uk/index.php?main_page=product_info&cPath=66&products_id=146 good for lots of other trials bits as well
  8. 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.
  9. Yes you can take the rocker feed from there but the oil filter must go in the return to the tank I see a lot of bikes fitted with the Terry Weedy oil tank

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. For the tank http://www.terryweedy.com/products.html
  11. 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.
  12. This year's TT has now been cancelled.
  13. 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.

  15. 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. .
  16. 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?
  17. 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.
  18. Hi Wiggy a great story of a bike that has obviously given lots of pleasure to you and your family. Thank you for the information regarding the gears is second low enough to be useful in sections if you need a bit more speed than 1st
  19. Couple of Bantam build questions please, 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
  20. You are very welcome, congratulations on your winning ride
