The bike can take it. Look at options that can make you cooler. Like captain itch or similar deflectors.
The best way to cool off is to get out of the traffic. If you are like me and in hot traffic daily, you'll get used to it.

Oil with fans or at least a oil cooler. Makes a huge difference if u want the bike to run the same all the time. Even my 88 needs one I don't care what some say that you don't need it. It helps keep the motor from getting all clattering in the heat. I also have the head coolers and wait till they shut off before restart, drives my gal nuts sometimes. Today took a while at gas station being it's over 90°F, got off interstate then had a red light or two and the oil cooler fans kicked on head fans been on most the day. Also did DK custom trick with only one crotch gaurd on the right to flow air around rear cylinder, this keeps motor cooler and my ecm is on that side.

hey theres the post Ive been looking for. 09 ultra classic, 501g cams, SE slip ons, SE super tuner pro, I havent noticed the engine getting very hot & the EITMS has never kicked in even tho Im in AZ & riding in 107 degrees in traffic. Only gets 30-32mpg but I assume thats to keep in running cooler.
