Pre-65 Bikes

I am about to have a front wheel built up by Central wheels . Is it best to go for WM1 or WM2 width, do they give a different profile on a Michelin tubed eg. the WM2 wider width rim gives a squarer trread profile? Thanks.

If you have a spark and you don't get a bang or pop after putting petrol directly into the barrel any ideas what this means, is the timing totally out?

I know very little about these bikes which I believe were ridden by Dave Rowlands and Mick Bowers, do any of them remain, were they very special. If BSA had perseverd with them might they have had a Bultaco beater?

Hi Guys. Here

I purchased a project C15 (1960) with no head steady and then bought one off of eBay. The one I purchased has a flat bar to connect head to frame clamp but it did not seem to fit so I used a simple spacer. It all fits together but is too wide and interferes with the gas tank. Is this the wrong head steady? Could someone describe what the correct one would look like? It looks pretty simple to make....maybe just longer where it attaches to the head. See the picture.

Can someone explain the rules on pre65 yokes ie new billet yokes. Is it something about where the pinch bolts are?
