Had Sampson true dual pipes, big sucker a/c, HD tuner with map, and dyno done on a 2007 deluxe and she runs very hot. Any ideas why?

 

When you say you have the HD tuner do you mean the SERT or did you just get a Stage 1 dowload? Also, don't know if you run it or not but synthetic oil will cool the bike down a little do to less friction of moving parts.

 

Do you have heat shields on your duals?. If not, that and the fact that your leg is next to the left pipe could make it "feel" hotter.

I doubt you'll notice any significant difference in temps by switching to syn. Wife and I have identical year 96Bs, one with syn, one w/o and they run same oil temp +- about 3 degrees. But give it a shot.

 

need more info, was it a dyno tune or run? what fuel management, what do you consider hot?

 

dyno tuned, fuel management was downloaded map from screamineagle tuner, 250-260 degrees
