I just got an email from Dave Hunter at Micon (UK) informing me my new head pipes are on the way. He says they rejigged the head pipes and had made several changes in addition to the others (flanges, leaks, etc...). The new headpipes now clear the oil cooler, the fanhousing, and the oil pipes with no spacers, there's more fairing clearance on the left hand side, and they got a better angle on the silencer.
