NO SOLUTION TO HEAT PROBLEM stop wasting $

[07POSE]

I've tried the Thundermax and the Power Commander. Neither of these reduced the excessive heat coming off the exhaust. The heat has caused the chrome to flake off the pipe and caused browning on the heat shield. The AFR has been adjusted until flames shot out the pipes and the bike would barely run.

Next up is to change cam's.

Harley Davidson Engineers told me the EPA rules do not allow a simple way to circumvent the emissions standards, but HD would not tell me how to bypass how to fix the problem.

What kind of luck has anyone had on changing their cams?

What are the specifications on the stock TC 96 cams?

Eh - Stage 1 (ECM Flash, A/C, SE Exhaust) and a HD Oil Cooler and my bike is running right in the heat range I like.

For the record - if I can feel the heat, then I feel better about the heat rejection qualities of my engine. I'd rather the heat be on me than building up in my heads. Which leads me to my concerns about the loss of the "Y" pipe on the '09s. The "Y" pipe helped cool that rear cylinder at the exhaust port, giving it more surface area for which it could reject heat.

I tried this too, my engine doesn't run hot. The oil is around 260 and the IR thermometer reads around 300. It's just the pipes that. \

You wouldn't know the specs of the OEM cam would you? Or anyone who has changed the cams?

Thanks

I don't personally.

I've been a little timid about replacing the cams with all the talk about runout.

I wonder how much money has been wasted trying to correct this crappy problem. The best solution is to sell the pile of crap. Seems HD impresses those who don't know the problems of the owners who suffer from the problem.

SUMMARY OF INFORMATION

This post was started 12-21-2007, 06:30 PM

To date nobody has offered any evidence of a solution to the heat problem that so many people suffer from.

I have ridden my Ultra with the heat problem for close to two years and the only damage is cosmetic where the chrome is gone from the head pipes and has started to rust and the chrome on the heat shields has hundreds of heat related pitts and are turning brown. This is a small trade off for the enjoyment I get in riding.

I hope all those from Harley Davidson who bad-mouthed the posts on this site have lost, because they have contributed nothing. I had already tried everything they suggested with no significant results, but they had not read the post from the beginning and did not know what they were saying had already been done.

For those who have convinced themselves they have fixed the heat problem - congratulations.

Its time to ride,

cams help a bunch, headwork and cams help even more. a tune (correct timing ) more yet. typical 96 bagger with cam, heads, tune no longer gets hot (except where any HD would heat up---lugging in city traffic). have done many 07 96 inch baggers and they become a pleasure to ride.(neccesary to overcome the steep gearing and crazy timing) only done a couple 08 DBW, but same results. have not done any 09.

bigboyz has a 4 gas on their dyno, maybe they will chime in.

All I can say is since I did SE Tuner, SE AC and Supertrapp Mufflers, my 08 FLHT ran cooler and quicker. It made quite a difference. I doubt I'll even have it tuned, I don't think it would make any difference.

As someone mentioned before. It's time to ride and stop trying to fix what can't be fixed.
08 FXD - Stock exhaust, Xied's, SE A/C kit. That's it for me. I'm not wasting any more money to get mediocre results. Just ride it till it breaks.

It's been a while since I've been on. Since then I picked up a 250cc dirt bike. The single pipe comes off the right side and feels nearly as hot as the Harley sometimes. Hard runs can get the header glowing also, just like my FXD.

Redline 20/50 will drop any motors temp by about 10 degrees....thats a fact.

Atta biker!!

[Bowtie18]

I'm sure it's been said, but exactly what are folks expecting??

Granted, it should be a bit cooler, but how much cooler do you expect?

I ad metrics before my 09, and even the water cooled bike was far from cool.

In case ya didn't notice, that thing your sitting just inches away from is an engine. They get hot.

Suck it up and ride, or don't ride.

Me, I'm getting ready to gear up and ride. It's a sunny 45 degree day here in Delaware! I might be thankful for the warm engine under me.

Bowtie,

The complaint is not heat when riding, it is mosterously excessive heat, particularly on the right leg when one sits in stop and go. I've been riding HDs for a long time and only the strokers I've ridden heat up like my 96ci, and they were not as bad. Going to true duals has helped as has the xieds. I am in the process of adding an A/C and race tuner and then I will have it dyno'ed the way I want it which should help a bunch in stop and go. If it's not enough, a set of cams will be next although like the true duals, cams with a decent overlap will tap into my lower end, but that overlap will cool this engine a bunch.

Any engineer worth their salt will tell you there is no problem that cannot be solved as long as you are willing to live with the consequences of the solution.

Best, harry

whats a good cam for heat solution on a 08 ultra if only running a/c ,pipes and pc111?Anyone?

[Bowtie18]

Well, I've got 4600 miles on this 09. and the only thing I see that is monstrous about the heat is the amount of complaining I see about it.

Honest to God himself, I think it's excessive the amount of whining about it.

Just my opinion, nothing personal!

I have just never seen as much complaining about bikes as I have here.

I had a Suzuki Volusia and a Yamaha Road Star prior to this HD, and the sites dedicated to those bikes have a much smaller amount of complaints compared to the HD sites.

That is no exaggeration either. It is just stunning to me.

This bike is not 1 degree hotter than my Yamaha was. Not one.

It is hotter than the Suzuki, which was water cooled, but not by much.

I think this is a great bike, and in my 4600 miles, I've ridden in heat in the mid 90's, stop and go, and down to the lower 40's today, just a great ride in the country, and I don't see the big issue.

Is it a bit hot, yeah.

But I finally got the Stage I download yesterday, and I can already tell a difference.

I guess if I'd been riding HD's for 30 years, I'd see something different.

But every brand has thier bikes running lean due to emissions standards, and that is the government's fault, no HD's.

Ride any air cooled bike out there, and I bet you find they are all a bit hot. Well, more than a bit.

The stock pipes on my Road Star ran one pipe right under the side cover on the right hand side.

I couldn't even leave my foot on the ground at Rolling Thunder, that is how hot it was.

But some Vance and Hines Longshots, and a re-jet did that bike a world of good.

We all know that the pipes get hot from the lean way the bikes are tuned, and that there are things we can do about that.

But only so much.

I suggest a nice long ride, instead of dedicating 20 pages or ranting about what is really an issue that all bike makers face.

Blame the US government, not the bike makers.

And just go ride the damn things like you've all stolen em, cause it isn't getting any better.

And Water cooling only does so much. Trust the word of one that has owned one. It helps, but it's no miracle cure.
