Engine cooling shrouds and Exhaust test fit

Waiting for replacement top cowl so got on with trimming down the engine cooling shrouds.

These came in the engine box that I bought and already had the mod that puts an air dam in the back of the shroud so that incoming air flows over the cylinder heads and is then forced down the back of the rear cylinder head instead of just washing out at the back.

I found that all the indented hex heads that secure the cylinder top plate and exhaust manifolds are odd sizes and don’t fit any of my socket drive hex heads or even my allen key set !

I cant get at the manifold bolts as the socket will need an extended head to make sure I miss all the cylinder fins etc that shroud the fittings. These all need to be loosened off so that I can get the exhaust temporarily fitted to estimate where the lower cowl needs holes for outlets.
