 Re: Copper[?] valve seat One of our members was apparently told by a specialist head shop recently that 1200's had copper valve seats. This is only partly right.
The "inlet" valve seats were made of a bronze/ aluminium alloy, & according to my Gregories workshop manual, the exhaust seats were cast iron, which is not good for unleaded fuel.
