Engine Heat

Sharky1948 · Oct 4th, 2007, 11:50 AM

I'm in the process of purchasing my first HD. I've read about issues with excessive engine heat (at idle) for the 2007 models. My question is, how real is it? And, is it a big enough issue to wait for a 2008 model?

It's a real issue but how much time do you spend sitting still. I added the TFI fuel management to mine and while it runs much better, it didn't cool it off that much. The 08's are just as bad from what I hear.

Cams as well as ignition timing will greatly help in this department. The stock cams are EPA compliant and there's another reason for the heat, they can't breathe.

Thanks for the quick response and insight!

my 08' heritage gets very warm but i would not call it excessive but then i have never ridden an earlier bike and my 05' metric gets just as hot.
I have read that a good 2-1 pipe a fuel system and air kit and getting ride of the active intake and exhaust helps them run cooler but would mean they could fail emissions and noise regs when it comes to test time

Some days... I'm just glad that I'm "stuck" with an "antique" Evo.

Good Luck with your decision... whatever you buy, it's doubtful you'll be standing still long enough for a real heat issue.

My 2007 Heritage gets quite hot on very hot days. When air temps run from 92 to 102+, the oil temp gauge reads between 235 after a long run, then hitting up to to 250 degrees in stop and go traffic.

I purchased the RSJOriginals heat shields back in mid August, but didn't get them installed until late September. I only had one good ride with them so far where the air temps reached 94. While I could still feel heat coming off the rear head, it was NOT the intense, blistering heat I had before installing them. Plus they look cool!

I'll keep evaluating them through next summer.
