I took the engine out. Again. Sigh. But I have it down to a fine art now actually. Takes a couple of minutes. Decided the double clutch springs were far too strong so I removed the inner ones to go back to normal. Only I buggered those god-damned horrible mousetrap spring taking them off so I can't reassemble anything till I get more.
I also turned the speedo drive upside down. It needed a little modding to do that since the bolt pattern isn't exactly even and to make sure the oil drain holes weren't covered. Now I can run the cable straight to the back of the speedo. I also fitted the dynamo housing. I tried measuring the backlash in the dynamo gear but I found that near impossible to do so settled for 'some'. There is no binding with the thinnest paper gasket I could manage. Ruairidh pointed me to this article talking about it: http://www.ba7c.org/technicalArticles/dy...Cover.html but it doesn't actually answer the question of what's normal or correct. What do other people do?
That article also answered another question I had I think which is what are the lower two dynamo fasteners? Stud with nuts or bolts couldn't work. Not enough room to do them up. I guess they are slotted screws? In which case I might need to modify a couple of bolts since I don't have them!
