Velo club owners in the States have mostly post-war swingarm models; MAC, MSS, Venoms, Vipers, and Thruxtons, as these were the mainstay of US sales (not many sales to the US pre-war, although we do have quite a few which were imported later). As our rides tend to be long-ish, there's a high concentration of 500cc Venom Clubman and Thruxton models. The ohc 350cc KSS models are often enlarged to 450cc or more, to keep up with the bigger bikes - this was a common mod in the 1940's and 50's especially, when American buyers were clamoring for larger displacement engines from British manufacturers. Several small motorcycle parts suppliers (such as Webco) provided their own cylinder barrels and pistons to bring the 350cc MAC and KSS engines up to 400-450cc. My own mkIV KTT has been brought up in a similar manner, by fitting a 79mm Norton International piston, which gives almost exactly 400cc.
A few hardy souls brought out their rigid machines on Saturday to brave the

Although pleasantly warm at 70 degrees at the 9am start, by noon the temp had climbed to 101 degrees, as we roared through the canyons and along Lake Berryessa; I'm certain a few nooks in the canyons were 110 degrees, as it felt like a blast furnace at times. My Sunbeam objected a bit by nipping up (too much fast fun and no oiling on the top end), so the remainder of my ride was sedate...
We were graced this year with the presence of fellow blogger Dennis Quinlan, whose site I frequently poach for excellent articles on Velocettes, Chronometric speedometers (used to be Dennis' business), and TT history. Dennis has an interesting KSS-engined special in a Scrambler swingarm frame. We were too busy taking pictures of each other for our respective blogs to get a good portrait shot...
About 25 Velos showed up, with a few interlopers like my 'Beam, a couple of Commandos, and two newish Guzzi v twins, which go like stink, and were ridden down from Canada by Cory and Vivian Padula for the weekend (!). That lovely blue Venom will forever be know as 'Denise's bike', as it
If you're in the Napa area at the end of May next year, drop me a line, and come for a ride.
