As fitted no expense spared
Pic 1 shows how the 400 pipe wants to sit due to the lug it goes on , on the 400 is horizontal .
Pic 2 is not a rocket science fitting . First the original mounting lugg has been removed as it is lies against the breather tube . The pipe which is under no pressure as it only dumps oil in the frame is held in place with a trimmed down ,
rear bracket which clamps a lever to the bars

.
I have done 60 mile since fitting , no leaks
I do not intend to weld lugs to support this cooler as it sits pretty tight as is . I may thread a bar with rose joints and go from one of the tank brackets .
