Thanks for the reply - the thing about stock is that there are very few all terrain tyres in stock sizes. The only one I've seen is TKC70 4.00-18 64T M+S rear - stretching to 120 gives a much bigger choice. The tip about deflation before assembly may well be a win. BarryH - great data - thanks! Thes...

I don't understand it! I've seen several videos where people have 120/80 metric tires on. I've watched this video where the 120/80 is just rolled in, no problem. But the camera angle doesn't show the brake shoes. https://youtu.be/tGlkR3nYa2Q?si=o5cEbQPBlLbBhpXJ&t=551

Carbs are off and I'm waiting on some rebuild kits. Its been stood for a long time I think. My last project was a Ducati I boug...
