After 5 hours on bike, I found the intakes were within spec. The exaust were both at 20mm. which is at the tight end of spec. So I pulled out the two shims and they were both #182 pads, so I replaced them with #175 pads. My clearance now is 27mm a little on the loose side. Is this going to be o-k ? I was figuring that the exaust valves would stretch the most from the heat, makeing them fall out of spec faster if I would have left them both at 20mm. Maybe I should have put 180s in there ?
