  1. I have to work from home. The commute is great....less than 1 minute from bed to coffee now. Saying all that, I cannot wait for normality again.
  2. Cheers mate :-). Figured it was after looking at the drawings. The more modern stuff confused me a touch. Not to worry...ordered new bearings and just waiting for them along with some shims. We are still in lockdown mode here in NZ for another week before going to a slightly less restricted level 3 so plenty of time to play in the garage!
  3. Had a look in a manual I had - I really need to look through these really carefully before asking questions! Ring in question is an oil baffle - see item 22. I guess it is better in than out....

    M66 rebuild

    Some photos of an M66 engine undergoing surgery...before I started all the rest!
  5. I used some EP2 grease. Orange and sticky as anything. Stringy too so it got everywhere.
  6. After a long time leaving the poor old M66 is the doldrums, I have started on the gearbox. Got it apart, got new bearings and gave the cases a bit of a clean (soda blasting is kinda fun!). I have a couple of questions now..... This ring I am pointing at. None of the more modern references have it. It was behind the 204 bearing on the primary shaft. None of the vendors have it on their 1° shaft and the pic below doesn't show it: However, my old Russian book does See part #20. I asked a Russian mate and he tells me it is an oil washer, for want of a better term. He knows what it is in Russian but can't translate it exactly into English. What is it and do I need it? It would mean the 1° and 2° shafts need to be reshimmed - the main point of this exercise anyway. If I don't need it I will leave it off.....unless one of you tells me otherwise.
  7. I used http://www.dynamoregulatorconversions.com/ for my 6 volt bulbs.Headlight bulbs are pretty much fit and forget http://www.dynamoregulatorconversions.com/led-headlamp-bulbs-shop.php .
  8. Jonny, try this https://www.aliexpress.com/item/32832751907.html.
  9. Check out the bike in the headline picture :-) https://www.nytimes.com/2019/10/02/travel/kihnu-estonia-women-unesco-folk-culture-tourism.html?action=click&module=Editors%20Picks&pgtype=Homepage
  10. You could contact VAPE ignition systems for this http://www.powerdynamo.biz/eng/systems/7027/7027main.htm. You could then dispense with the battery altogether... https://www.vape.eu/ish-350c495456
  11. Why are you changing to 12 volt? I know all the pros for doing so but there's enough LED technology to cure the lighting issues. My BMW and old Citroen car are still 6 volts - I toyed with converting them to 12 but now it doesn't seem to be much of an issue. Saying that, it's quiet at work and I was up for a challenge so.....https://www.bikebandit.com/blog/lithium-motorcycle-batteries Might be helpful, might not. It is interesting though :-) Any pictures of your bike?
  12. Here you go. As Propwash says, the smaller curl goes around the tang on the stand, the larger curls goes on the rear engine mount spacer. My engine is out but the picture shows the location.
  13. Sorry Paul - best laid plans , etc....mother in law very ill so things are a bit up in the air. I'll see about getting to the shed as soon as I can but in the meantime check this out - You can see one end of the spring on the centre stand tang and the other end off into what appears to be where the engine mount spacer sits.
  14. Think this might help. Centre stand has a tang on it for one end of the spring. Can't recall where the other end goes (engine spacer??) but I can take a pic of my M66 later today. http://sidecarpro.com/BFA-centre-stand-spring.html
  15. Thanks! I am coming to that conclusion too. It's the vertical carb studs I'm after - got to wanting some originality for my M66 :-)
  16. Ebay....only way for me :-) The heads definitely look Ural. The holes for the oil are the same, the valve area is the same, Ural bits fit and they fit Ural engine. The fins of the newer heads are thicker and better finished. Everything but the intake - that's way bigger. I'll take these to a cylinderhead shop and will see what they think. My job changes in a couple of months time (maybe....might be later) and I am hoping the increasing responsibilities also bring more $$$....I'll be able to afford getting these heads worked on :-)
  17. I bought a couple of cylinder heads to use instead of the low, low quality ones I had. The first set had really poor castings. The new set, even through thick layers of cosmolene, look much better. Only thing is the intake holes are much bigger. They are slightly oval and are 35mm at their widest point instead of the 28mm my other heads are. Markings doesn't have the usual IMZ - it's a more abstract mark. Above is the legend AK5M7 and there is 10101502. I'll post pics when I remember how to do that - I have the new heads in my gallery. Just need the heads on the engine then I can bolt the lot together to check if it goes. I want this bike done by this year....it's been way too long in pieces! Edit - pictures added. Much easier on a desktop!
