Hi
The head from my BN1 is being repaired and the guy from the shop asked me to supply 1 exhaust valve and 1 inlet valve. However the exhaust valve is different to whats on the head. The valve is larger, 2mm in length and 3mm across the valve. The original valve is stamped with what looks like MOWCO AEC 9/5
Can anyone identify this valve and is it common to increase the exhaust valve size on the 100 engine. The inlet valve was the same.
Cheers Graham
