That's what I did... got the XiED from nightrider.com and that enriched the fuel mixture enough to help the bike run cooler, with better low-end grunt, and barely affected the fuel mileage. Only about a $100 plug-n-play change that you can do yourself in about a half hour.

As others have said, it's not really an "overheating" issue... except for YOU when riding in hot weather!... but just more of a lean-running condition that a minor change like this can fix. Or, the major mods you do (later?) can also cover it.

Enjoy!

 

They run what Harley says is normal for this engine.

 

bought a 10 SG in august, been kickin the idea around since I bought it about what I was going to do about the heat from the cat. After riding it for the last few months (approx 4000 miles) and renting one in arizona a few weeks ago and running around in the desert when it was 90' decided just to put on a SE Nightstick muffler and leave it stock till it goes off warranty. It really does run great and now it sounds right with the new muffler.. Know eventually I'll buy that S&S air cleaner and some new pipes but for now I'm just gonna ride the **** out of it.....

 

Well, finally!! I imagine that Frenchbiker is in the same boat I've been in for the past year. Nightrider had trouble getting the IED's to work with the 09 touring models. The other 09 Harley's weren't a problem so getting them for your Deluxe wouldn't have been an issue anyway. As of the release of the 2010 models, and a full year of tinkering, they still hadn't gotten them working to their satisfaction on the 09 touring models. I'd pretty much given up on it after literally checking the web site every month or so for the past year and being told they still don't work. After all this time, I hope they got it right!

Ride Safe,

As others have mentioned, they run warmer because of the lean fuel/air ratios. There are a few things that work: synthetic oil, oil coolers, and fuel management. I use all three and never had any problems.

 

Never seen one overheat. They will shut themselves off if that would happen. Do a stage 1 with a/c, slip ons and fuel management and top it off with Amsoil and you'll be fine. Or, ride it stock and see what happens under warranty.

 

Wow! Someone actually suggested to someone in the "Big Sandbox" that they add "IED's" to their bike? That could take on a whole 'nother meaning with a Vet. Of course I am just giving the OP a hard time. God Bless our men and women who are serving and who have served. If the Corps would take me back I would be there in a minute. But they say I am too old. What kind of BS is that??

 

I don't think you have much to worry about on the newer bikes. Rear cylinder ignition shuts off at a set temperature, then acts as air pump, cooling oil and motor. Adjustment to injection/ignition map on 07 and before, already there on 08's and up, I believe. My 07 will shut off rear cylinder at stop lights if I am waiting for awhile, then ignition/injection kicks in as soon as I disengage clutch or engage throttle. Funny smell and sound, but happier motor, and rider. Syn3 helps too.

 

Syn 3, PC III for re-mapping & no probs here in the Pacific NW. In Eastern WA where the temps are significantly warmer no issues either. I don't believe the rear cylinder shutdown on 08 or earlier models. I believe the 09s & newer however do.
