Hi All,
I am about to restore a 1955 shooting star and it just happens that a friend of mine has just finished a resto on 1955 shooting star as well.
I have an original BSA data book for 1955 and it states that the engine sprocket is a 19 tooth, clutch 43 tooth, gearbox 19 tooth and rear sprocket 42 tooth.
My friend set up his bike to those ratios and rode the bike and found that it was reving very hard and seemed to need another gear, he has now gone and purchased 20 tooth sprocket for the engine and will try it soon.
Would like to know what other people have experienced with their bikes.
Regards Andy
