Thanks feller, I'll have to track down a 22mm x 1.5mm pitch bolt over here, it's good to have definite dimensions.
I'm afraid there's no real progress to report on my XL project. The crankcases are now separated but the flywheel is still attached. The main bearing I can see doesn't look too hot - the outer race is showing signs of pitting - so that just confirms that I'll replace all the bearings and seals suggested in a previous post.
