Title: S28 VALVE SPRINGS?
Post by: DADSBIKE on 10 April, 2017, 12:39:13
I have a 1928 BSA S28 (SV 493cc) the exhaust valve spring seems very feeble, the exhaust valve can be lifted off its seat with my fingers.....is this normal?!....... if it's not, any idea where to find replacement...would an M20 or similar fit?

thanks
