as the BSA Spitfire -Y is doing well, very well with its modified crank (1982) and EI (2012) topspeed and revs are steadily increasing.
the engine and framenumbers still match, I believe it is the last Spit with matching numbers, so I started out to have an extra engine prepared. when a rod drops in a othernumber engine it is a pity but not the end of the world. probably when a cheap frame turns up I will build a extra bike. but engine first.
needle bearing timingside
standard axial setup with shims
SRM oil pump and filter in the oil feed line
newby drivebelt and clutch
9:1 pistons, std bore
