Exhaust Header Temp.

[Super D.]

@Super D. I have 2 Rockets...an '09 standard running a Reband system and a '13 Roadster running a CES system. Both bikes have been dyno tuned. Both bikes run hot on the leg. Sitting on my bike lift absolutely cold at ambient temperature then fire up and let it idle for a minute or so and my little laser temp gun puts the header temp right at the block in the 500 F range...not revving...just idling for a minute. So the answer to your question is YES...aftermarket pipes are hot, and YES I will eventually get tired of it and fab a heat shield. Both sets of pipes have been coated by the original manufacturer and two different shops since in an attempt to reduce the heat. My problem is that I like black, and black ceramic coating does very little to reduce heat. If you like the silver look you can have them put a ceramic coating on your headers that contains aluminum oxide which I'm told will provide significant heat reduction. Haven't tried that yet as I'm not a fan of shiny stuff so much. Hope this helps

BTW...I would expect that the header temp gets well above 700 degrees when the rpms come up. As a frame of reference the tip of a cigarette burns at about 750 degrees F when not being drawn on. Anybody want to volunteer to get a cigarette put out on your leg every time you go ride?

Thought not...

Edit: Having said all of this I still want one of Paul's systems to replace my Rebands. Them things are moto **** in my opinion. Sexy work there @Paul Bryant

Than you sir.

I thought I read on here somewhere about relocating the rear brake reservoir. Any know about that?

Some of the headers require the reservoir to be moved because of the much larger collector pipe being too close to it. It's just because of the shape of the pipe.

It has to do with the header exhaust heat Champ. I was riding yesterday, and I'm pretty sure the rear master cylinder got hot enough to boil the brake fluid.
Is this how it's going to be moving forward?

Yep, I think I boiled the brake fluid. I am going to put in some high temp fluid in there and see if that fixes it. Relocating the rear master cylinder will be the last option.

Don't use silicone based brake fluid! That will rot the hoses.

I bet you could get a couple spacers and longer bolts to space the master cylinder out some from the mount. not sure how much you could go but heck 3/8" would make a difference on heat. I think that's what Carpenter did on the earlier pipes they had made @Steel would probably know?

Yes on the Roadster you have to move it out about 3/8 of an inch. Carpenter supplies the spacer and bolts with their exhaust.

Good to know. I just flushed the system, and replaced it with Motul RBF 600. It has a much higher boiling point. If that doesn't work, I will go ahead and move it out three eights of an inch. Thank you very much for the information it was very useful.

I have not experience this problem. Yesterday was stuck in traffic at a dead stop for about 10 minutes. the air temp was 92 degrees with about 82 percent humidity. Pipes got very hot but no harm done to brake reservoir. Just went out and checked brake fluid. It is fine, no problems. Not saying you do not have a problem but it just seems rather odd that you are having so many problems. I have placed over 700 miles on the bike since installing Paul's system and really have not experience any major issues. Did use the heat gauge borrowed from work and after riding hard for 57 miles in 90 degree weather pipes temperature was at 550 degrees. Average speed was over 70 MPH. Warm yes but I wear these wile riding. Naw I wear them all the time. Just food for thought. Knowing that the exhaust system from Paul was a Naked system (No Heat Shields) Kind of expected the pipes to run warm. Even the fancy pipes on the Harley run hot (Vance and Hines) At times due to the location of the floor board can get rather warm. I spent a lot of time prepping the bike prior to installing the pipes from Paul. I do all my own work and maintenance on the bike. Ran Tune ECU, double checking everything. Even replace fuel filter which turned out to be required anyways. Not trying to stir the pot but find it very strange how one person can be so unhappy with the system while another can be so Tickled Shi$less with the system. Just saying.
