Thanks for the posts and the suggestions!
I'm kinda feeling my way along here, so ideas welcome. I am pleased the tinware is all there and I'm already thinking on ideas to make a filter to fit the airbox.
The replacement regulator has arrived, after a bit of digging around on t'internet. This was chosen after recommendations on classic bike forums, plus it can be used on 6V as now or 12V if I chose to uprate. Another reason for choosing this one is it fits inside the old reg case, so will keep the original look. However, maybe I've bought this too soon? Read on....
The engine was missing the rocker inspection covers. You can buy them new with various words/logos on top, but I wanted something that would fit the finish of the rest of the rocker cover, so eBay produced these, which will come up nice.
The engine machining/grinding requirements are beyond my skills and garage tools, but I've decided to have a go stripping the gearbox. Never done one before, but encouraging comments from a BSA forum suggest it's do-able. If I don't try I won't learn.
I'm in the middle of pondering what to do with the K2F magneto and the E3L dynamo. The magneto is in a very sorry state, as a previous owner dismantled it and damaged it in the process. The magneto is also missing the contact breaker assembly, amongst other parts.
The dynamo is at least in one piece, just missing the screw to hold the cover on, but after so long I'm not trusting it without a strip and rebuild.
One of the quotes I've had to get a company restore the mag could come in at over £500 and the dynamo at maybe over £300
. Before that, I had intended to keep the electrics spec as originally designed, 6V and all, but with those costs I'm beginning to be tempted by the idea of 12V and modern electronics.... I'm only scratching the surface of this subject yet, more quotes, thinking and research needed. (Maybe I did buy that new reg too soon??)
Haven't got as far as frame and tinware finishes, that's next month's research...
(Tunneruk - is that sort of tank resto something you'd take on?)
