Unknown engine cover

Found this engine cover on a 84 VF1000F. Never seen it before.


It is more than likely from the race VF750,it’s an HRC part and probably made from magnesium

I ask google and the hrc covers on the pictures look a little bit different like this on my bike. What are the plugs for? Ignition timing or cam/crank position? Can i earn a lot of money, when i will sell this piece of racing history ;D ?


Yer a jammy git if it turns out to be a HRC bit :slight_smile:
