Adding fuel to your mixture is important but will not notice any huge jump in temperature. Wouldn’t blame the FP3 so long as it’s mapped correctly. Would wrapping the header be okay ? Reply Think maybe the V&H FP isn’t the right step and need a suggestion. Put luv jugs on but the fan just pushes more heat on right leg. Tried true duals with V&H slip ons and V&H FP. Late summer the bike is so hot on right leg I can’t ride it. These motors run hot.I was told the same thing when I visited the Harley plant in York, PA ReplyĢ006 road king running so hot burns my legs no turner stock bike ReplyĢ012 Road King. Harley said thats about right for the twin cam engine. My Heritage with the 103 reads about the same. If you’re concerned about keeping it cooler. I also installed a Jag 10 row fan assisted oil cooler and that very pricey Screaming Eagle extra capacity oil pan. Since I have installed the Love Jugs my bike has never again entered that parade mode or whatever they call it. I watched your video on the Love Jugs cooling fans system & purchased one. It used to go into the single cylinder mode anytime I got in slow or stalled traffic situations. I have a 2010 ultra limited 110″ pushing 130hp/128torque. I had a yamaha roadstar with v&h pipes and I did that to them with great heat reduction but did not have O2 meter. I did put vance and hines slip on mufflers and that is the only modification that has been done to the exhaust system. I want to wrap my pipes and catalytic converter with a wrap to control the heat getting to my legs. I bought one of those digital dip sticks and always interesting to look down when idling and check oil temp hmmm this page is food for thought especially in central queensland Reply I like to service my own bike and with out it no worries. Everytime you change your oil filter you ended up with a small leak it even happened when I had the dealer change my oil. I had a oil cooler installed by the dealer when I bought my bike and it was a piece of crap. So engine temp sitting in traffic can be 400-500 degrees and we want to bring that down to cool the oil. As we all know, oil coolers work to cool the oil and a cylinder fan works to cool the engine. This all depends on where you ride and riding style as Bob mentions in the videos. So what is the normal operating temp on a 96.oil temp etc Reply Hi Mike just read your blog about over heating cylinder on your bike I have a 2013 cvo 110 road king 10 minutes into riding right leg is burning the same problem you have rear pot getting to hot factory mechanic said it’s normal ha rubbish should have kept evo take care Steve Reply Have got a 110 road king cvo.right leg after 10 minutes is burning of back cylinder been told its normal by harley shops the only harley I no that over heat at rear why and its air cooled hmmmm it’s 2013 model Reply Yes 103 runs hotter but this is ridiculous Reply paid over 20k for the bike and were miserable 2 days into bringing it home. I’m running into same deal right leg is burning me and wife on a 2015 SGS I am not going to spend a dime on heat shields etc. You got to be kidding me right buying extra stuff to have a comfortable ride after spending halrey $ The DrysDale godzilla v twinn is another design that would be more appropriate for the street I think. There are large displacement v twins,like the 139 Orca, that are based on the evo that are interesting. I think HD needs to look at the v twin with fresh eyes. I have a friend who also ordered an 01 ultra too, he got the 103, and has had no issues in 60,000 miles. I have always wondered why, when I ordered my 01 ultra, If I wanted a 103 it would have come with heads without compression releases. It seems as though It’s modifications have been troublesome. There are aftermarket oil coolers and cylinder cooling fans, that we review on Fix My Hog, to help bring the standing and running temp down on any model. Finally they added a wet head to some touring models and oil coolers on most touring models. HD is asking more from the same TC 88 design and that is causing the heat issue. Hi Len, Thank you for all your comments on the site. Though now considering CAD design, better material and better engineers I’m just keeping faith in the creators that these engines are fine Reply Not to say Harley hasn’t made design blunders in the past. I’m hoping the Gods at Harley who created these motors have engineered them to take these higher temps. Compared to my sons 883 his bike feels just warm. Even at cruising speeds the rocker boxes are as hot as my exhaust heat shields. Articles on Harley-Davidson How-to and More
