Engine heat

[357454]

Hello all: I have owned several Harleys in the past and have been riding my Ulysses for only a few months and really enjoying it. Now that summer is just around the corner and it is heating up here in Utah I am experiencing quite a bit of heat while riding, especially on the inside of my right leg. I am looking for suggestions to lessen the heat. My last tourer came with Willy wings on both sides to divert the hot air thru the frame, I also wrapped the exhaust which helped a lot. Any recommendations for the Buell?

There is a "comfort kit" available for the Uly that includes a scoop for the right side of the engine and a heat shield for the exhaust.

Does anyone have pics and info on ordering one?

I added the comfort kit to my 2004 XB-12S and it made a very noticeable difference in the heat. It went from scalding hot to warm. That and EZ clutch pull kit (lowered the clutch pull weight), made all the difference in my commute.

Just added Comfort Kit today. Noticeable difference in leg cooking. Followed directions and went slowly... Average+ Bike mechanic. New Castle Harley and St Pauls both have the Kit and vents

What's that box doing? Is there a fan in the new scoop?

Good advice... I also own a 883 sportster and a Suzuki sv1000 (V twin). I am familiar with Twin vibes. Added the circle earth mod and it really helped smoothing out the idle and low throttle acceleration. I check the batteries and top up their charges on a regular basis; So far so good.

No additional fan... The side panels that fit over the rear brake reservoir and the opposite side redirect the exit air flow even more towards the back. Since I have installed the kit and panels the fan only runs when I stop the bike; a big difference then without. My leg is no longer getting even mildly cooked. Highly recommended unless you are a heat resistant type.

The box channels air away from your legs and in combo with the side panels moves the air to the rear of the bike. No additional fan; although if you could arrange for a second fan to have a pitch a third below the first one... If music be the food of Love ride on.

Maybe you can get your fans to do something like this:

Can you please explain what the "circle earth mod" is?

I own five Saabs. Another extinct worthwhile manufacturer. Many ground problems. Many. Since I have been keeping them running since the turn of the century when I picked up my Ulysses I automatically cleaned all the grounds; then reinforced them with the help of the article cited. I think it runs better... Can't hurt. Cleaning and protecting Grounds can't hurt and can keep you on the road.

The comfort kit alone helps some, but the real improvement was realized when I purchased an Ecm with the new fan logic. Fan runs all the time when above 15 mph. It rarely runs at all after shut down and only at low speed.

I found speed based fan control would roast my leg because its the fan exhaust (right side under the seat) that does it. Leaving the fan alone to cool the engine temp-based only worked for me.

FYI, for free anyone can get the ECMDroid program from GooglePlay, use a wireless connection like a Buelltooth, and set the fan settings to whatever you want, including clicking on the "speed based fan control" option.

I live near St. Paul Harley and they’ve always been great supporters of the Buell brand. If they don’t have what you’re looking for, they’ll try and find it for you. It seems the comfort kit is pathetic way to go. Gtreatjob on the install.

You live in a great part of the country for touring. Hope you get the right leg heat thing figured out.

What exactly is the “circle earth mod?”

I agree 100%. I installed the comfort kit on my 09 xt without the fan logic update and it helped some. It wasn’t until I obtained a new Ecm with the new fan logic that I really noticed the difference. My only concern now is how long until the fan gives out since it runs all the time above 15 mph.

One data point for you - I just changed out my fan. The old one appeared to be the original. 2008 model XB12XT (fan also had a 2008 date code), 65,000 miles.
