The wife and I took a short ride today-80 mile round trip. 35 miles of easy back roads, 45 miles of open highway. Ambient temp around 90. I have a 05 FLHT with 40mm CV, 204 cams, VH true duals, SE Ign Module. On the trip there, I saw 240 on my oil temp guage-sender in the pan. We took the highway home and running 80 on the highway, she climbed right up 290 plus. I slowed to 55-60 and she eased off to about 260. I know there has been lots of discussion about temp with the FI bikes, but I've not encountered such with the carbed bikes. Recently, I changed the mufflers from VH ovals to some modified stock pipes (the wife complained the ovals were too loud) and wonder if this might be the problem. Unfortunately, I installed the mufflers the same time I installed the guage, so I don't have a 'before' and 'after'. What say you, oh great ones?
