Hi this is my first post, i am building a pre 65 bike out of a 1960 B40 star i have almost finished the engine (C15t gears, Alpha roller bearing big end & timing side main, PVL ignition and Amal 626 carb) i could do with some advice on frame mods ie swinging arm ,steering head angle etc

I have built the wheels with bantum hubs 18" rear wm3 R18/4, front 21" wm1 R21/2.75. the rear shocks are Betor 13.5" units and the forks are B25

hack saw time...

get the whelbase and head angle of choice by 'cutting the top tube and 'gently' applying pressure on the front wheel to the right figures are achieved. and for those on a budget i'm told that the engine can be mounted higher and the lowere rail/s raised by removing down tube
