Hi all, I'm new! I have an XS650 with a Halco 840cc big bore kit and oil cooler and she's fitted with 1 3/4" stainless pipes. Because of the location of the oil cooler takeoff I need to wrap the exhausts... But I've heard that wrapping the headers can increasae the temperature of the exhaust in the ports, and with the bore of the pipes being oversize as well, I'm concerned about burning out my exhaust valves. Any advise or info is greatly appreciated! Cheers Liz
