I posted this on Flash/Xied's I figured I post it here as well
I have just finished a 700 mile run to the Pa Grand Canyon. (It was great)
Now, the Xied's worked great, I was getting 49/50 mpg, running the bike in 86 deg. weather at 55/60 mph the oil temp never saw over 207 deg. I was also riding with my wife and a bag off the back. Oil temp's in stop and go did see 225 deg. If I saw anything around 240 deg. I would have stopped, or got out of there but, it never got that hot. The plugs were slightly tan and the exhaust tips are like a blackish gray.
This product works well for me:
