Paul Dunstall modified stock Nortons to racing specs while maintaining the street legal aspects. From the stock chassis the stock engine was removed and modified. Special attention was given to a well fitting and perfectly aligned lower end. Pistons have a 10 to 1 compression ratio and are spun of cast alloy to obtain a low expansion rate. Combustion chambers were reshaped for high speed combustion, intake valves wre enlarged, exhaust ports were reshaped and polished to a mirror finish, valve train was lightened and Hyde conversion Lockheed dual discs were installed. Dunstall Nortons have won the isle of Mann in England. This bike was originally purchased in England and has had 3 owners since new. It is in excellent condition and runs great.
