ST1300 heat - problem SOLVED.

On Ron Ayers parts blowup, it looks to me like rubber mat goes under airbox, on top of throttle bodies
I have a sheet of heat resistant rubber (drop from work) I can make one easy with, am I correct?

I think the rubber pad goes UNDER the throttle bodies if i recall correctly. I distinctly remember it being UNDER the 5 way tee when I added hose/tubing to the tee.

No as stated above me it goes under the throttle bodies. So tank off airbox off very long Philips to get to the clamp screws then a block across the frame with strap to lift the throttle bodies out. The long part of the matt tucks down. It's a big enough job I would consider trying tank bolt spacers first. Are you sure the matt is missing. Can you see all the way down to the engine v?

Yeah, I just replaced a hose in there can see metal
 
Before I've found this topic I was in one step from purchasing new GL1800 (aka ST1800).
That heat in crotch makes me go mad.

I've tried to follow way given in this thread, however did an additional shield to prevent hot air from access in V near thermostat.
It made from 2 layers of non-ferrous foil 0.35-0.50 mm or so.

One could try same before removing upper tank and airbox as a lightweight solution.
I'm also going to add insulation as OP proposed in 1st post.

Happy New Year =)

I'm just glad I've never had the heating issues, and some of the other (wobble / weave, etc.) events some here have reported.

Not saying your issues aren't real, only that mine is well- behaved and loves me lots.

That's what your comment sounds like: :nanner1:

How is that helping Komrad Vlad?

Happy New Year.

Just be aware of one thing….i have repaired several damaged wire harnesses and switches, on bikes that tried this method.
It creates an oven effect, and cooks things.
While the rider may not “feel” the heat because of the foil, your trapping it in areas that can/will cause damage.
But with that said, it was on the internet, so it must be real and correct right?

You may want to compare parts from earlier and older ST1300 models. Honda added some shields to the fairing and frame for heat management and it helps. no doubt, you might be able to replicate some of it on yours.

It also feels like they might have done some work on the mapping over the years. After replacing the ECU on my 03, the throttle snatch was no longer as jarring as it used to be, but also the heat was no longer melting my shoe soles either. But that of course is harder to duplicate.....
 
Honda did not add the metal shields inside the lower cowls for heat management, but rather to keep the header pipes from melting the plastic.
You will also notice that they put a metal heat shield on the inside of the left muffler to keep the heat off the brake caliper and lines as well.
Honda did change the mapping from 04 and up, which is why most the sub wire harnesses will work from 04 to current, but the 03 had a very specific harness.
Think of the 03 models as Honda's learning curve bikes ;)
Our Russian friend didn't say where he was feeling the heat, up high between the seat/tank, the side of the frame, or down lower near his feet.
Heat can be caused by several different issues, from tuning the bike better, choice of oil, coolant issues, seat position, or rider position on the bike etc.
 
This shield only traps the air behind the radiator. The air wil not flow anymore thrue the radiator and then thrue the sides away from the motor.
It is possible that this just will heat the motor more.

My bad, didn't intend to sound like neener, neener, ... only that it's highly unusual for my fortune to bring me a hassle-free bike. In my life, if you believe in luck, I rarely win door prizes, I don't get windfalls, I don't win raffles, but all things considered i do ok.

Bought my low-miles 1300, and all I / we (thanks @Igofar ) had to do was replace the SMC, as my brother in law had quit riding it for a couple years.

This is why I don't go to Vegas or to Biloxi, and why I will never buy a lottery ticket.

Just saying I really, really, really like my ST1300, and of all the bikes I've owned it's only second to my '97 Blackbird in problem-free riding and smiling. I'm often surprised at the number of complaints I see here, but then I just have to realize the internet has two purposes:
1.) Seek out help for issues, and
2.) To vent their frustrations.

All the "average" people who blithely go through life, just ride, wrench and enjoy theirs and we don't hear from them as often.

Hello @Igofar ! Thanks for that pre-caution, I do aware heat currently disturbing pilot only, may possibly cause damage to other bike components, that are more necessary for machine operation =)
The thing is...
This shield only traps the air behind the radiator. The air wil not flow anymore thrue the radiator and then thrue the sides away from the motor.
It is possible that this just will heat the motor more.
... I was targeting to re-route heat flow from radiator to outside side fairing, @PanRider1300 . That foil shield is not interfere with LHS harness and RHS minor wiring. It's only increasing heat in the vicinity of radiator fans, as I interpreting situation there.

Why I thinking it works for better heat routing? - that home-made shield couples with thermostat bracer, which makes it gusset shaped -> this makes (I presume) upcoming flow to be rested on cylinder heads and eventually to spit outside thru side fairing "breath" windows. In other words: I'm not sculpting an oven down there.
This makes main heat channel be routed somewhere, except V and rest "capsule" within upper tank and frame, where the only way out is to pilot's private part - crotch.

<...> didn't say where he was feeling the heat, up high between the seat/tank, the side of the frame, or down lower near his feet.

With regards harness possible harness melting - could you please point out particular sections being affected?
<...> But with that said, it was on the internet, so it must be real and correct right?
Of course I would love to have an advise AND bike operation is more important, than comfort, because fixing things on roadside is not something I looking to end up.

Totally agreed, I was tried "soft" measures, such as: saddle insulation, saddle 3d mesh, upper saddle position. No luck there.
Also, after long day ride motorcycle begins to smell gasoline (from overheated upper tank, I guess).

This winter did full system flush with 2 step cleaner and 3 rounds with distilled water. Also radiator was separately washed with kitchen acid.

Thank you folks for sharing experience BTW. I'm eager to stop baking my testicles while riding =)
 
The two last pictures are the ignition wires on the left side just behind the radiator.
