With the slight modifications of increasing the number of holes in the intermediate pipe, and increasing the length of the fish tail outlet, the exhaust system [text crossed out] is reasonably quiet and efficient. We had trouble with the brass sleeves at the joints. These have been changed to steel. The cutout will not stand dynamometer work owing to the springs losing their temper and the valve sticking. On the road we have not so far had any trouble. There is difficulty in turning the split ring nuts with a spanner. Hs.{Lord Ernest Hives - Chair} | ||
