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.

engine specs:
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
reuse the head, single carb

some picture of the bush removal are in the link

anyone an idea how to remove the torrinton bearing from the transmission, which direction to push?

keep you posted
regards Anne
