It takes about 1 hour of interstate speeds for the engine and all the metal to fully heat soak. The hotter the ambient temps, the less the air flowing past the engine cools down the engine. The difference in felt heat between 85 and 95 degrees is pretty significant.

Also, since our bodies run at about 98 degrees, when the air flow past us is warmer it does not cool us down.

When it is below 96* ambient temp, the faster we ride the more air flows over us and the cooler we feel...but when the air get the same or higher than our body temp, then the air flowing past us no longer is cooling us down, but actually feels hotter.

Even if the speed limit is 80 mph, if it is 100* outside, I will probably ride around 70 mph, cause at 80 the ambient air (not from the engine) just makes it feel hotter the faster we go.

Yes, the engine "******* out" is from it getting too hot. When engine temps hit around 270* the metal is expanding at different rates so much that it loses tolerances, resulting in a loss of power, and reduction of engine longevity. This is common with all 07-up Twin Cams, air-cooled or twin-cooled.

Adjusting the tune will help, but it will not solve the problem...the tune/air in (via the air cleaner) and air out (via the exhaust system) all work hand in hand to make the largest difference.

 

I'm not sure which tank lift to buy? Also will it change the seat position to use a tank lift?

Thanks

 

The wife normally doesn't have much of an issue with heat, and we've ridden plenty in very hot weather. But one thing she does notice; when the wind is strong from the left side it definitely tends to get hotter on her right side. The air comes out instead of going back and down. It's only with the wind from the left.

I've partially shut the vent on the left lower and fully opened the right lower, and pointed the right side fairing vent outwards to blow air in towards her, same for the left side to kick the air out, and that seemed to help a lot. You can really change things a lot just by fiddling around with those vents.

 

there is a minor lift to the front of the seat if you go with the DELUXE OPTION.
There are bushings under the tank mount toward the seat. This change for me was a benefit as it gave more of a saddle fit, and I no longer felt as though I slide forward. You can of coarse go without the Deluxe option and just the tank lift. I have tried with and without, I prefer the Deluxe spacers. As stated for seat, and to open up more for the rear rocker box.

 

2.5 inch?

 

I choose the 2" deluxe version for our trike really seemed to help. I just recently added Air deflectors and I was amazed with the temperature reduction. My 09 fuel gage was off before and no better now. ride safely Fearless

 

Fearless,

Thanks a ton for the pics! It looks like you have everything Kevin has recommended.

I don't know for sure yet how to lose the cat. Did you change your pipes for a catless header?

Are you glad to have the Power Vision Tuner over having a Dealer put your trike on a Dyno?

Thanks again,

Brian

 

You can get a decatted head pipe OEM on flea bay but given my choice I would go aftermarket. No dyno around me for miles forva trike PV does it all and more. Tuners are a personal choice .I like DynoJet Power vision. I have a OEM head pipe my is an 09 no cat.

 

Fozworth, check out on of my earlier posts with pics on removing cat yourself.

Yep, what Screwball said! All I did was remove cat and have SE tuner. Of course on a super hot day sitting at a long stop light will get a tad warm!
