i put a oil temparature dipstick in mine. that gives you a good indication. my has never gone over 195 degrees, even when it was around 100 degrees outside and 2 hours straight riding. im not sure of jetting on the 88, but ive got 185/45's in my stage 1 bike, 95 heritage. by the way, beautiful bike. the heritage is the sexiest bike made by any manufacturer period (my opinion).
