  1. I’ve decided it’s spring now so you can get all the toys out again.
  2. That’s really sad to hear and I’m very sorry for your loss. He’s left a fantastic legacy for someone to take forward and finish and I hope your family can one day see it on the circuit and feel justifiably proud.
  3. I think its post war, the long number is national stock number, the predecessor of the NSN.
  4. The oiler on the WD/C and CO is also an engine breather so angle it down. It should have a little disc in the block but I think these are often missed.
  5. Heavy enough to know it’s a good trailer and light enough to not feel like your towing a tank when not loaded.
  6. I’m certainly no towing expert but I think a good quality trailer helps with towing. I once borrowed a car trailer and it put me off towing until I had to do it again and hired a Brian James one. Totally different experience!
  7. This isn’t mine but noticed it on FB for sale. Its a C with CO mechanicals.
  8. Engine oil is as good as any, you can see on some bikes, people tried to fit sealed chains but they are too wide and cut through the chain case. What ever you do, it will likely still leak.
  9. I would try and source a good Cush drive clutch but they are hard to find now so may take a while. The non Cush unit you have now is from a much later machine, I’ve seen lots of them over the years.
  10. Henry Jenkins & Sons.,Unity Works, Victoria St., Birmingham. Produced between 1914 and 1918 under contract from BSA.
  11. This series is also handy. https://www.ebay.co.uk/itm/115719615903?chn=ps&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&mkscid=101&itemid=115719615903&targetid=1814673649102&device=m&mktype=pla&googleloc=1007079&poi=&campaignid=19089547614&mkgroupid=142438599285&rlsatarget=pla-1814673649102&abcId=9303859&merchantid=6995734&gbraid=0AAAAAD_Lr1cADOxPeV243zYz2lGaOTcP1&gclid=CjwKCAjwhdWkBhBZEiwA1ibLmPdDw0ORpn6G0MkZqHxyVaHEKgf3nVaQezgtf727OkFjNJopZli43RoCUIUQAvD_BwE
  12. Have you got a copy of this booklet? https://www.ebay.co.uk/itm/264392878563?var=0&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338343596&toolid=10001&customid=eb%3Ag%3Avms%3Aeb%3Ap%3A264392878563%3BCjwKCAjwhdWkBhBZEiwA1ibLmGj3D2r19XEiAFeOUS2fOmCtOW7sfXcvJeN1HvsW3Nl6fqZV4aYwvBoC1PIQAvD_BwE&gbraid=0AAAAADmMgighZP2AgDls66y9Geq23LcY-&gclid=CjwKCAjwhdWkBhBZEiwA1ibLmGj3D2r19XEiAFeOUS2fOmCtOW7sfXcvJeN1HvsW3Nl6fqZV4aYwvBoC1PIQAvD_BwE
  13. They aren’t CO, the cases are larger at the rear. The Post War CO was assembled from left over WD/CO parts and the very last COs used C crank cases with CO cylinders. If yours were one of these, you’d have a Model CO serial number on the front of the case and if I remember correctly, new drain holes like the CO case. It could of course have been a non factory modification that someone has later ‘undone’ and not realised what the hole was originally for.
  14. No probs, reading back on both posts, neither of them read how I meant them to.
  15. Attached is a photo of a WD/C crank case with oil return hole and WD/CO crank case with hole used for 5th stud and 2 new holes for oil return.
