Cheers folks,
Well I changed the rod after qualifying Saturday and broke it in Sunday pre-finals (half a tank just gentle idle and a tank gently on the track). Engine ran fine, but notably a fraction richer (should of leaned it up for the final!) even though head clearance was same at .51mm. To that point what should the head clearance be?

Will run it a little harder next time, and will get that v3.0 broken in too. Will report on that later.
