'08 Ultra overheating

I need some info andhelp from someone in the know please.

I have an '08 Ultra with 2800 miles on it. This past Sunday I went on a 400 mile run with some friends and thebike maintained a 260-350 degrees Fahrenheit temp on the idiot gauge most of the run.This reading came from the temp gauge I had the dealer install, replacing the air temp gauge when I purchased the bike.
I am running synthetic fluids on the bike. I called the dealer Monday morning and they are telling me that I have nothing to worry about becausethat the '08's run hotter, and since I am running synthetics I have nothing to worry about.
Can someone please either tell me that they are full of s**t or I am, either way I would sincerely appreciate some info on this.

RE: '08 Ultra overheating

I had the very same thing. Bike is very hot, specially when not taking the highway.
After a lot of consultation with other riders and mechanics I decided to get the stage 1 done. Replaced the mufflers, replaced the airfilter, re-mapped the injection and it indeed does run much cooller.
IMHO definitely worth it!
Good luck,
Dries

Thanks Diebolt for your reply.

You have the same color bike that I have, I forgot to mention on the post that I have done a Stage I, S.E.R.T., K&N, Filter, D&D Fat Cat Exhaust, Dyno.
I will check into the Xieds you suggested.
Once again thanks for your reply.

Thanks Driesb for your reply.

I have done a Stage I, K&N Filter, S.E.R.T., D&D Fat Cat Exhaust, Dyno. We ran just about all highway miles this past weekend and the bike ran hot in my opinion. I do not believe that it should have gotten that hot. Dealer says nothing to worry about, I have my doubts.
Once again Thanks for your post.

RE: '08 Ultra overheating

Thats running real hot my 07 bike with stage 1 kit with SERT was running 220 to 270. I fitted a Jagg 6 row vertical oil cooler bringing temps down to 180 to 230 with my dash mounted temp gauge.I have the sender unit mounted in the sump for the temp gauge

RE: '08 Ultra overheating

You can do a lot with the SERT, but not all dealers will. My dealer said if I bought a SERT he would tune the bike to where the air/fuel ratio would drop all the way down to 14.6:1. Which would cool the bike abunch. Check the thread out mentioned above about IED or XIED. 14.2:1 and 13.8:1 respectivley. Why spend all that money for a SERT if all you want to do is cool it down???.....Oh yeah, there is better performance with the IED or XIED as well.
