Valves

[pgnz]

80' valves are bigger than 78' valves but only one side
exhaust or inlet can't remember but think it's the inlet
valve that's bigger by a mm..

I'm looking for valves for XS1100E 1978. I found a set online for "Yamaha XS1100 1980-1983 Engine Valve Set". Are these not suitable for my bike? Colin
