Trip Miles: 156 - Moving Time: approx 2.5 HRS - Average Speed: 60 MPH - # of Stops: 8 Data Record Stop
Total Gallons Used: 4.937 Gallons - Miles Per Gallon: 31.59 MPG
Grade & Brand of Gas: 91 octane/10% ethanol, Chevron (Desert Hills, AZ)
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Observations: Contrary to conventional wisdom; my engine oil temps (EOT) tend to rise equally at high speeds as they do in stop and go city traffic. Granted we dont have a lot bumper to bumper traffic around here but my experience shows that when traveling @ 75+ MPH for an extended period of time on a hot day, my EOT rises and if I slow down to about 65 MPH, my EOT drops by at 10-20 degrees. I guess what Im trying to say is: city driving is NOT the only environment which will cause your EOT to rise!
Upon retuning home from my hot weather test ride, I put the TG in the air to check the new Jackpot head pipes for any signs of discoloration. These pipes have approx 4,000 miles on them since being installed and there is some very slight bluing on the cross over pipe but thats nothing like the total discoloration of the entire stock head pipes! Also after parking the bike after this long ride, the pipes did not have that loud/long heat contraction ticking/tinging sound that the stock head pipes made and I was able to touch them after only a short cool down; all of which suggests that these pipes are more heat efficient and do not retain heat like the stock pipes do. And yes oldmsoko; I did detail the undercarriage while my TG was in the air!
Comments: YAHOO! Im absolutely <ecstatic> with a Max. Engine Oil Temp of 240 * @ 118 OAT! If I can consistently replicate these results, Ill be one happy camper! I wanted a test route that would incorporate as many various real world riding conditions as possible; IMO this test ride is a fairly good indicator of how the above listed mods collectively reduce excessive engine heat in a hot environment! My TG performed strong throughout all gears, even when pulling 6% grades; I attribute that to the Wood TW6-6 Cam. As I previously reported, the low end torque on the Wood TW6-6 Knight Prowler Cam is fantastic; as a matter of fact, the TW6-6 provides a noticeable power increase throughout all of the gears. After approx 4,000 miles since installing the new cam, I am unable to detect any bad manners from this cam; it has a nice little lope at idle but definitely not bone rattling, nor will it vibrate any parts off your bike; just enough pulse to let you know its there. I have not experienced any bog or hesitation upon rapid acceleration nor have I experienced any detonation problems with the cam; this was a real concern of mine due to the fact that we only have 91 octane w/ethanol available in my area. If the cheap gas were a problem with this cam; I would think that it would have manifested itself during this hot weather ride and while pulling 6% grades!
Not only does the TW6-6 provide some additional performance boost but as M3 pointed out in another post; the TW6-6 over lap design may also assist in reducing the heat some.
Im a little disappointed with my gas mileage but in all honesty, my style of driving isnt conducive to great MPGs so Im probably not the best person to look at as a gauge for average gas mileage. Also, if running a MAP with a richer AFR and sacrificing some gas mileage is what it takes to make this TG run cooler than so be it!
Conclusions: Prior to the installation of the Jackpot Pipes & Wood TW6-6 Cam; the other above listed mods previously collectively lowered my engine oil temp. by about 30*, from 300* to 270ish on a 110* day; therefore, I conclude that the addition of the Jackpot Pipes & Wood TW6-6 Cam lowered my engine oil temp. by another 230 degrees on a 118 * day! My test results are in an environment that is hotter than most TG owners routinely operate; therefore, I assume that TG owners that operate in less severe conditions can achieve better results with all of the same mods OR possibly the same results with a few less mods; i.e., oil cooler fan, parade fan & 20W60 synthetic oil; providing they dont encounter a lot of bumper to bumper stop and go traffic.
Folks, Im fairly certain that WE either licked or are extremely close to licking this excessive heat problem that Harley claims is just a figment of our imagination. I say WE because, had it not been for the generous, unselfish sharing of experiences, information, expertise and encouragement by many members and suppliers on this forum; I would have never been able to get this close to a solution. This forum has proven to be an invaluable tool and Im deeply appreciative to all that constructively contribute on a regular basis! As the saying goes paybacks are a bitch but Ill try to repay by assisting wherever and whenever I can! Now pat your selfs on the back, dry your eyes; put the handkerchiefs away and pass the Champagne!
I apologize for the lengthy post but after fighting this problem for so long, I just could not refrain myself from babbling on about these results and an apparent victory!

Boys of Summer
It's been a long ride from last August until now and you deserve to relish the moment. I won't bore everyone with my mods, the ones that keep current know I took a slightly different route. We have good gas 93 no ethanol most places here, when I do have to put 91 in I use the 108 Turbo Boost Octane additive. I also top out in the city at 240 deg. on 95 to 98 degree days. Ambient has not been quiet to the 115 mark. It also will climb towards 230-240 for long runs or lugging the engine.
I have not went with a cam yet so I still have a little performance problem riding two up and loaded in 6th gear. I weight 290 myself so I'm not sure how much I will get from a drop in. It is as comfortable to ride as my old 03 FLHT and it was a cool running bike.
I was really bent out of shape when I first got the Tri on Aug. 8th last year. I am satisfied with the Tri now for the most part, still doing a slow burn for having to reinvent the wheel at my expense.
Got a lot of help and a lot of people had some patience with an ol carb guy. If you are new to the forum and bought a 2010 Tri especially, you better do your homework. You have the experience of the Trail Blazers on this forum to fall back on. Or is that Tri Blazers, no pun intended!

That was some detailed report ....
118 Degrees ?
That is insane .... We have finally hit over 90 this past week for the 1st
time in 3 years for an extended period of time. It actually hit 103 at our
house and it was unbearible. 1st time ever were have been running our
AC 24 hours a day in a row ..... YUK !
I'll take a nice 75 degree day anytime over theis heat & humidity :-(

Good report, Jimer!
Do you attribute the gas mileage to the cam and low octane fuel?
I have many of the "anti-heat" mods but stock cam. In 90*+ heat my oil temp level's at about 240* w/20-50 synthetic and parade and oil cooler fans. I wonder if it will run even cooler with a different cam + the 93 octane we have back east?

I think that the cheap 91 octane w/ 10 ethanol has a lot to due with my gas mileage, also I am running richer with my PC-V so that is also a factor.
If you are indicating engine oil temps of 240* on a 90* day; I am actually doing much better in engine oil temp reduction than you by indicating 240* on 118* day. I think that you and I have very similar mods so the only thing that I can attribute the difference to is that I run Red Line 20W60 synthetic oil. However; unless you consistently operate in OATs of plus 80*, its probably not worth the change.

Great info. It seems like all your hard work and dollars are paying off.
Can you tell me what you are using for the heat reflective material under the seat and where you bought it? I ordered the Alaskan Sheepskin Butt Pad and Pillion pad on Wed. but I would also like to get rid of some of the heat that comes up through the seat.
Thanks again

I still can't understand why they would put a hole in the cup of the seat. Certainly isn't a vent for cool air! Unless it's for flatulent riders!!
