Damn engine heat!!
It's about 87 here today, just rode on the highway, from my office to my home (7 minute ride) at about 75MPH....damn that thing blasts a lot of heat on me while riding; right on the lower part of my legs...
I've had many bikes before this, but the only bike I can recall blasting heat on me like this, was a recent model Goldwing. The temp gauge was only showing 1 bar...no wonder...the fucking engine runs cool because all the heat vents on the rider...:P

Im going to heat wrap the headers on my 12r.. On certain sports the header is 1/4 inch from the radiater.. I'm also going to add a push fan on the other side..

...adding a push fan to move the air out instead of in? Is that what you mean? Wrapping the headers...won't that heat the headers up more?

find all of this bizarre.. still maintain the ones we rode didnt do that..
I wonder if the complaints are only here cuz we pointed out the "lack" of heat.
still perplexes me.

The engine heat seems normal to me; it's the heat management that's the issue...it's all in the way they exhaust the heat away from the rider/bike. A classic example of this was the 03-05 FJR...riders complained about the engine heat and it seems Yamaha addressed this on the 06. I don't know why the Vegas bikes didn't exhibit these symptoms, but if you were there in January and it was say 65 or so, you wouldn't have noticed nuch heat...

I disagree.. was 70 one day... mid 60s the other day... here at home in those temps, esp if it's colder out the heat is more pronounced on my bikes. the 12R roasted me and it was quite convenient.. kept my warm on cold days... no noticible heat came off the 14s I rode... definetly different than my 12R...
but hey... that's just me... (oh... and Mike.. he noticed the same thing)
oh well...

Wrapping the headers...won't that heat the headers up more?
Wrapping the header would contain the exhaust heat inside of the header and direct it out the exhaust pipe. The only down side to wrapping them would be that the temp of the "downstream" pipes would run hotter, and the temps coming out the end of the pipe might be a bit warmer. Overall though, you would be effectively "moving" the heat somewhere else because it can't radiate out of the header pipes. This is usually a good thing, as the header pipes would normally radiate heat right onto the engine block, and through the body work and onto the rider's legs.
Another not-so-great thing about wrapping the headers is that heat wrap generally doesn't like to get wet. So if get caught in the rain too often, it will deteriorate the quality of the wrap, causing it to break up and eventually come off. Heat wrap isn't always a good "permanent" solution for non-track vehicles.

the stock zx12r double fans 02-05 pull the air in, Im adding 10 inch fan from the other side to push the air..

I noticed on my 10R that the exhaust runs much cooler than the stock exhaust did; in fact you can put your hand on it within a minute or so of shutdown, mostly due to the lack of backpresure I assume. I would also guess that the headers are running cooler too now. So I would imagine that an aftermarket exhaust would generate less heat coming through the rad...anyone running pipes now noticed if the heat factor is less than before?

This is on the 12R or a 14 you are planning to do this?

last sunday was 92 degrees in houston,tx and 95 humidity. that is nasty.
correct if i am wrong guys. i noticed that the zx14 does not have any protection, plastic cover in front of header like my busa had. could that be some of the problem with heat direction to the leg.

Does anyone ceramic coat the headers, inside and out ? That really keeps the heat inside the headers.

On cars, yes. The entire exhaust system on my 944 Turbo is ceramic coated. The coating really holds in the heat, and on a turbo, more heat equals quicker spool-up time... that's a good thing
Seems that for heat containment purposes alone, ceramic coating of headers on these bikes would be a reasonable idea, I just wonder about the added heat on the underside of the bike... the lower plastic panels would likely get hotter unless you coated the entire system.

Mine cooks my knees ...I looked where my knees are at and they are right on the grills ..If i move the 1/2 inch from the grill no more heat...If you look on the back of the grills you will see some tin foil glued to the back side ...Maybe adding more might help the problem ...

There are those of us that understand the benefit's of wrapping the header and we do.

Ya...if I move the legs away from the tank slightly, heat is much less of an issue, but I don't ride that way...particularily when traveling at speeds. I'm most comfortable on any SS bike when hugging the tank with the knees...also provides for greater stability at speeds, especially in strong crosswinds. If your knees move around from air, it tends to have an effect on the side to side momentum.

Well with out the wrap my 14 cooked my ankles. It was about 85 here in Galveston,Tx. Riding slow on the beach and the fan was doing its job by blowing the heat out the vents. I felt like it was cooking on my ankles. The header wrap will definitly work and makes alittle more torque. I had it on my blackbird and because i ride in the rain the wrap started to come lose in places. Mostly under the bike. The wrap on the down pipes stayed tight. I'll do it when I buy a header.

In this case heat is good, it assists with scavenging!
Why else would anyone put that ugly mummy wrap on their machines? LOL

Guys don't use that header wrap... It does work but looks like ass and will take half the life out of your pipes ... I have seen it happen over and over ...Take you pipes to a JET HOT Coating and have them coated inside and out ... They will look geat for years and run just as cool as header wrap...

Do you think that an aftermarket pipe/can will send less heat through the rad?

No, a properly mapped engine, with better flowing exhaust, making more power will create more combustion heat. In fact highly modified engines often need bigger rads....!
(cars) but some nikes could use bigger rads too....turbo, supercharged, all usually need more cooling
More HP = more heat everywhere
