my hrc kit for my new 08 just showed up anyone have any imput on if i should wrap the head pipe or just put the gaurd back on it from the stock one[/b]
i just wrapped mine last weekend, its kind of expensive ($40) and smokes like crazy for the first 20 minutes or so. but it does keep alot of heat off your leg. i only wrapped mine so that i can ride in shorts in the dunes.
We wrapped the header on the black 450r in the quad-innovations 450r build topic. We used the same method used above. It works really well and looks very nice. We wash our machines after every race / practice and the black does come out. We have to re-spray the black thermo coating every time after we wash it....

i doubt it. proably take longer for the motor or at least the pipe to cool down.
some say moisture penetrates the wrap and depending on the pipe it can cause rust.
but for me, Im wrappin it for the look and to keep the dam heat off my leg.

It is "claimed" that there are performance advantages due the heat being kept inside the pipe causeing the exhaust flow to exit at an accclerated rate. or something like that...
i used the thermo-tec 1" wide also. it looks pretty good if you take your time. i bought the wrap at napa but i didn't use the coating "yet". no one around here seems to have it. for the guys who did use the coating where did you get it at?
I never knew there was a different thickness... but it makes sense....
I use 2" cuzz its far cheaper in the long run.... but it is more difficult to wrap and make it look NICE where the neck bends...... however, this stuff doesnt last forever, and I have already wrapped my header several times, and the 2" goes a lot further.....
I have used both the supposed 'best' copper impregnated wrap......... and the 'tech' black thermo wrap...(actually Kevin's wrap....sshhh)..... both last about the same time and both will turn almost white after just a few heat cycles..... not sure if its the added heat from Nitrous use or not....but my black wrap turned grey before the engine was even broken in....and it is now almost pure white....(about 3 mos old)...but is still in good working shape..... what happens is the wrap begins to deteriorate over time and will need replacing...... mine usually lasts about 6mos of normal riding.....
I have never had an issue washing my quad and rusting the pipe......so I cant say if that is true or not, but in any case, all you have to do is start your bike up and let it warm up for a short while to burn all the water out of the wrap......
is there a performance difference? according to some.... yes, due to exactly what Martin explained above...the higher the exhaust gas temp, the faster the exhaust gases flow......... maybe John will do some experimenting/dyno testing with header wraps one day...but until then..... I cant really say for sure....
but it DOES keep the heat off the leg and is a HUGE improvement in this department........quite a noticeable difference if you ask me.....cuzz my pipe can really get hot.... hot enough to bake OFF my ceramic coating.....
what does the 'coating' do or 'suppose' to do for the wrap?
1. Helps keep the heat in the pipe
2. Seals the wrap to help keep it from deteriorating
3. Helps keep the wrap colored black, since the coating is black also.
I'll post a couple of pictures here shortly, along with my application method.
Ok, here's some basic application instructions that I had posted on another forum:
The header wrap can be a pita, but it definately gets easier with practice.
1st off, I started with the black 1" wide wrap (much easier to work with)
2.) I soak the wrap in water before applying (this probably "pre-stretches" it and makes it easier to apply)
*The directions on the wrap don't tell you to soak it, but the instructions on the can of sealer tell ya to soak the wrap before applying
3.) Start wrapping from the rear of the pipe up to the front (this keeps the overlapping ridges of the wrap facing rearward so it's harder for sand, etc. to get stuck in it)
4.) After the wrap dries overnight, it kind of "shrink wraps" itself to the pipe
5.) And lastly, I spray about 3 coats of the header wrap high temp sealer on the wrap.
To answer one of the other questions someone had, you can buy the Thermo-tec wrap and sealer from car performance warehouses like Jeg's Automotive or Summit Racing. A 50' roll runs roughly $30 and a can of sealer runs about $9.
Here's a couple of pix of my Raptor pipes...
I've had this wrap on now for probably 15 hours of actual run time and it still looks as good as day one.
As stated above though, after washing your machine, you should start it up to evaporate all the water out of
the wrap before putting your baby to bed...
as for the wrap i dont kno that ill want to have to rewrap every 6 monthes so another question wat does everyone think about this the hrc kit comes with bigger brackets to use the stock heat shild on the hrc header im sure honda put some r and d into this concept i just really wanted to du it if there was gona b a beneficial proformance increase
So i bought this kit(06+ Honda TRX450R TRX 450R 450ER Kibblewhite AZQP +1 Intake Valves Springs Seals) from ebay, for my 07 Er and i paid a “motorcycle mechanic” to install them, when he install the intake valve he didnt use the springs that came with the kit, he use the stock ones, because when...
Hey guys new on here but not new to 450rs. Anysways I bought a fixer upper 2004 450r and the first time riding it, it was getting extremely hot so I decided to pull the carb apart and check out the jets anyways it had a 118 main (stock) in it. Air box lid was on but has a full white brothers...
Hey everyone, I have a 2004 450r. Everything is stock except i removed my air box lid and has k&n filter, I ride from 6000-8000 elevation. Main is 118 pilot is 48s, before I removed the lid the bike ran great. Now it dies if you stab the throttle at any givin point while riding or sitting still...
I jetted to HMF recommendation on jetting 165 main, 48 pilot. Got the tusk adjustable fuel mixture screw.
HMF competition full exhaust, uni filter with lid removed and green wire mod done. Riding at about 500 ft above sea level.
It’ll fire right up with choke on then idle high. After I turn...
Hey its me again, so I've done the oil change and the manual says .82 quarts and thats exactly what I put in. I started the bike once everything was dine and it ran like normal. But when I checked the glass it was almost empty. I thought it just needed to be left alone and I did but the oil...
