I had a chance to take my bike on a couple of 25 mile twisty/hilly road trips to work last week.  I've had it re-jetted, Raptor petcock etc. I have the stock exhaust. After two days the exhaust pipe coming off the head was pretty blue. I have no frame of reference, but the bike seems to run fine, it bogged down a bit going up hills at 50-55mph ('86 four speed, so I chalk that up to gearing).  I'll be swapping the exhaust to a Dyna. Do I need to look at the jetting again maybe?
