Here’s the latest bit of interesting activity at Somerset Dyno. The photo’s show Harry’s longtime friend Bill Hodgkins, (ex british sidecar champion, TT winner and world championship competitor) 750 Norton sidecar being run in and set up for this season after an extensive rework and rebuild. It is now making a reliable 66BHP. The First race this year, was due to be Brands however British summertime took over and meant that it was cancelled through snow, therefore the first race will be in Belgium next week end. So good luck Bill lets have another win for Norton
So this weeks challenge is an R6 head that is being prepped for racing, it’s ready to have the relief angles cut for the valve seats, and the seats concetricity checked then we will assemble it with its valves and springs, fit it back with the engine, along with its Kent super sport cams and slotted timing chain wheels, this is where we hold our breathe and take very great care with the valve timing and checking the piston to valve clearances to make sure those millimetres give maximum power. There will be more pictures to follow up our work while we are doing this.
