Still working on the cooler installation. The right flange has to be modified so that the gap with the engine mount is at least 1/2". The picture shows the alterations I made.



Then I have to drill the two rear baffles for the magnetos cooling blast tubes. The black tube will be attached a bit later.



Then I have to drill the forward raight ramp for the alternator cooling tubing. I have ordered a 1" aluminium flange to install the tubing and have a nicer finish.



And last hole to be drilled, in the forward left ramp. As I will have dual mufflers, I have to ventilate both mufflers so that's where the left muffler will get the air from. (The right muffler gets it from the right rear baffle, installed yesterday).
