I was talking to Charlie last night and he bought up a few points that could be of interest to folks.
In the picture above, the chair was of Charlie's own design,as a young mechanic at the time with little spare cash,it was built with ingenuity in his spare evenings.He believes in the background is the 250 Bultaco of George Wiliiams and his brother,out of Minehead.The venue,probally Lynmouth or Stonedown (Exford).
One of the things he mentioned was the two stroke entry into sidecars,at one trial he watched someone on a big bore two stroke(make unknown,does anyone remember the bike or rider? Charlie thinks he could have come from up north,mind you we're in Somerset most of the countrys up from us! ) and thought that was going to be the way of the future.
After purchasing a second hand big bore twin pipe Greeves,Charlie said he spent countless hours trying to get the motor to produce the power needed for sidecar use.A huge lead addition to the flywheel,1/8" spacer under the barrel,a longer inlet manifold were just some of the alterations.It seemed successful,because after some good showings he was given assistance from Bultaco.
Once again,many thanks hillary for the photo.Regards Gary.
