No more hot butt

As long as you keep engine temps below 200f you will be fine.

You will still bake on a hot summer day stuck in traffic below 35mph
 
Gunny, looking good as usual!

I decided on another version of sorts. Found some pipes for the rear cylinder on ebay and had them ceramic heat coated in an 1800 degree titanium finish:



The header section closest to the head was coated inside and out, and I will test out the effectiveness over the weekend. Decided to wrap my pipes in a different way this time, as I had used one piece previously:



I have used the coatings successfully in the past with other applications, so we will see this time if we can get the reduction in the seat area. I will try the front header pipe later as the cost for the coating is only $126 USD.

bestem beware lots of their stuff unless stated 100% is not 100% carbon fiber. they lay carbon over fiberglass.

bike looks good fake gunny

IDK about wrapping titanium, but the 1800 ceramic coating has a nice color to me. I didn't want black or bright silver. It looks different in different light.
 
wrapping ti can cause these 3 things

1 it can't cool as well you can damage the material. Wrapping ti is a big no no. Some companies like akra use other alloys so i can withstand more heat then pure titanium.

2 titanium can crack from the heat

3 Because they can trap moisture and ti does corrode

simple internet search found this
 
So, update on the thermal barrier and Gunny, not to thread jack but I figured why start another thread.

Took her out for a spin yesterday with ambient temps in the 75-80 degree range. Immediately I noticed the bike ran "smoother" if that makes any kind of sense. I don't think I was imagining this and the bike "felt" like it was breathing different. I will have to do the front header and see what results when I get back on the dyno. One thing I read was that this helped reduce backpressure, so that might be the phenomenon I felt after firing her up and getting out onto the highway.

The ceramic heat coating has certainly worked as advertised. I have used it on my old Suzuki GSX-R 750/1100 years ago, as well as headers on cars, but actually sitting on top of a coated pipe is much different.

I would think that there was a different amount of heat. Some folks estimate a reduction of 20% and I would think that number is close. I did wrap the pipes as well but left the header tube section alone, since they coated inside and out.

All in all a low cost mod which help get rid of hot butt.

It's plausible it's having an effect on performance. If you maintain a higher temperature inside the pipe by 'insulating' then the gases essentially will be lighter/less dense and should flow quicker or certainly smoother? Like a decrease in back pressure? Having said that I would consider it quite a small change, who knows, maybe there's something in it.
 
Mutt, I have to say that I could tell a difference. With the Audi its a "butt dyno" but really stuff for cars is hard to quantify for sure, much like how it drives after you clean it. Haha!

However, this ceramic coating seemed to have reduced the backpressure on the engine a degree, which is probably why it "felt" different. I have over 13,000 miles and it is strange but seems effective.
 
Road my 1299s for the first time yesterday.

Jesus, it's ridiculous. Hot summer days in full leathers will suck. Im going to do everything possible reduce this.
