So never having an airhead, and before I go chasing my tail. I haven't done a compression check or checked float bowl levels (winter projects). Bike has 76K on it, accelerates fine and does 90mph easy on a flat run. That out of the way: On long mountain passes I can barely make 75 mph, pinned (only me on it). Particularly Snoqualmie pass here in WA. Or Pocheco pass down in Cal, were with a head wind I was barely making 65. So, I thought I'd 'ax all yous all, how's yours do?
