HI guys need some help, I have a 1971 bsa b25ss goldstar 250 and have had do do some engine work, when removing the inner timing cover the cam dropped out.....
now this is the problem my bsa book says there should be a dash and a v mark on the cam, my camwheel has a
DASH and a
DOT... which are5 1/2 teeth apart..
if you place the cam so that the keyway is at 12 O'clock the
DASH mark is 2 teeth anticlockwise from the centre line of the key way, and the
DOT is 3 1/2 teeth clockwise from keyway centre line.
My BSA book says use the V mark which should be 2 teeth clockwise of the key way. THERE IS NO V MARK.
so can anyone help me and tell me how i should set the valve timing... i will try to add a photo of my cam markings ....help please...
