Not normal. Get an EFI controller.

It'll make the fuel ratio more rich should you adjust it that way.

It's glowing because it's running too lean, you need a efi controller to richen the mixture. it's like changing the jets on a carburator. if you continue to run with it like that you will damage your engine!

Why would you let your quad idle for 5 to 10 minutes? That's the worst thing for a motor.

Every quad I've ever had, the header would glow red especially if left idling for a couple minutes. These headers are made from really thin metal. You may be lean, but even if you're not, it will still glow somewhat.

I agree, most people don't notice unless it is dark. All try it at night and you may be shocked at how red they get. No wonder we all melt boots and pants.
I also agree it's best not to leave any quad idling too long,

its just somthing iam used to from riding sport bikes, on my 600rr its supposed to idle untill the temp guage displays "99" so i fired up my quad last night to let my dad hear the exhaust and noticed my header was red

I noticed this on mine several months ago. I called my local dealer and they said its because of the titanium content in newer head pipes now and not to worry. I don't know if that's true or not but I'm runnin a map from Dave that is extremely rich and my pipe still glows if it idles too long.

So in my own research several buddies have a variety of different bikes, from stock to built, and every one of the headers glows after extended idling.

So in conclusion, I'm not worried.

I have had 5 quads over the last few years, and every one of them the header glowed red after a little while of idling. Idling a motor should not hurt it any more or less than running it at high RPM. As long as it has oil pressure, you are good!

I was at little sahara last weekend and a friend of mine was also on a stock 700xx both of us had glowing exhausts after riding at night, They would calm down to a dull redish glow after a minute or two of idling. He was running 87 octane gas and i had a mix of 91 and 110, and both our exhausts glowed about the same. I think its partly due to the high performance level of this engine and partly just the thin design.

Take your pickup out on a dark night, let it warm up, then get out on a secluded road, and hammer it. Run it up to 100 mph or so, then hit the brakes, stop, kill the lights, pop the hood, and look. Unless they're covered up by heat sheilds or something your exhaust manifolds will very likely be glowing red.

So I take it yours is not stock and runnin a 11:1+ piston?

atleastitsnotaford
10-29-2009, 06:34 PM
My apologies for the confusion............I have a 13t front sprocket, but other than that, bone stock. I know I don't need 110 gas but:
1. Honda recomends no less than 91...............so having a bit higher eases my mind when that half a gallon of 87 thats still in the hose from the person in front of me gets mixed in with my 91.
2. At little sahara, it's convienient. You ride up to the pump on your quad, fill up then go pay.
3. Well, I just love that grape soda exhaust smell you get running 110!

My friend uses 87 cause "It didn't hurt my last 4 wheeler." I guess he thinks he's saving a bunch of money on those 3 gallons!

I was meerly noting the difference in gas as it made no difference in the exhaust glowing. A fuel tuner (while a very good idea) may not be the 'fix' for this. My opinion, the fix is either get used to it, or get an exhaust with less iron content.

Did anyone else notice their stock exhaust glowing in the dark (red hot), even just from idling? Would exhaust/header wrap be beneficial here?

vfm2010
12-12-2009, 11:06 PM
yep, don't worry it's from the lean fuel settings to pass emissions. Header wrap's only benefit here (there are other benefits for modded engines, but not much for a stock engine) would be to keep your leg cooler, but i would recommend ditching the spark arrester to decrease backpressure if you do it with a stock exhaust. I would also recommend getting an efi controller( PC III/5 or dobeck/clone) first to correct the fuel curve especially if you plan on adding an aftermarket exhaust and air filter ( the big 3) later, you'll need it then anyways.

atleastitsnotaford
12-19-2009, 10:58 PM
do a search. there was another post about this subject already. The short of it was it's not a problem, but a fuel controller / aftermarket pipe is the fix if it bugs you that bad.

Will it hurt the engine to take the spark arrester out? i noticed when i did,it smelled like the engine ran more rich.The dealer told me it wouldnt do any good but make it louder.Any truth to that?

as far as i know.. it does nothing at all if you take it off... it's just there because some riding areas require it... and yea it'll make it a lil louder

atleastitsnotaford
12-27-2009, 04:36 PM
a friend of mine has his out, and comparing his to mine..........his is a little louder, and more prone to stalling than mine. Not bad enough to really consider a problem, but I do believe its because of the spark arrestor being out. It didn't seem to make his any faster.

12-27-2009, 04:47 PM
The chamber design is the power robber in the stock exhaust, As you said his shouldn't be any faster without the spark arrestor

Yep, he's running too lean.

Lemme guess, when at low RPM's he stabled the throttle it would bacfire through the throttle body and die.

How'd you know? lol. A light blip of the throttle as you ease out on the clutch, to get over that little ridge without going too far, and pop, got to restart.

Yeah these motors are set as lean as can be from the factory for the crazy California emissions. If you make it run even leaner by removing the air lid or removing the spark arrestor it's even leaner.

Sunday DBLxx and I were riding up the same sand hill and before he would get to the top his fan would kick on. Mine didn't kick on until my 3rd gear donut at WOT on the top of the hill and that was a good 5 circles or so at wide open throttle. (I must admit though, I'm set a little rich.)

Removing the spark arrestor will not make it run any leaner. The front of the muffler is where all of the restriction is, not to mention the header is what makes noticable changes in A/F ratio.

scuzz
12-28-2009, 08:47 PM
It will noticeably run worse I've tested it with spark arrestor, with the spark arrestor cut off and only the tip and with the whole thing removed, it runs worse for each part you remove. (besides sounding like poop)

I'm not making this up, nor do I have any reason to.

atleastitsnotaford
12-28-2009, 09:21 PM
Lean or not, it did seem to stall a lot more without the spark arrestor in there. And the sound is a matter of personal opinion. Granted I agree with scuzz, there are ppl out there that like the way it sounds without the spark arrestor.

scuzz
12-28-2009, 10:35 PM
Yeah, preference on sound is totally subjective, just like favorite colors and music.

I meant no offense.

Are you sure you removed just the spark arrestor? Spark arrestor's do not really limit flow which is what causes A/F ratio's to change. We dyno'd numerous quads in the past and none of the SA changed HP or A/F. They will change the sound but the restriction is in the actual muffler/canister configuration.

scuzz
12-29-2009, 08:47 AM
Yes.

I actually have two stock mufflers and cut the spark arrestor off of the "extra" tip I had. If you look at it it's actually perforated metal "screens" and I use "screen" lightly as it seems to me that it was more metal surface than empty or holed surface.
I agree with you that the muffler design is very restrictive as the outlet, which is on the bottom of the last chamber is barely big enough for me to get a finger in. None the less though, the spark arrestor would even further reduce exhaust velocity.

Thats due to extremely hot exhaust from way good power and thin metal in the pipe if you had headers on your car you could see the same thing at night on it too no problem at all just don't touch lol, I wrapped mine with exhaust wrap so I don't see it, that does help some on the leg but not a lot.

Ok we done some riding today and checked some exhaust temps pn the header. I used a laser thermometer that i have to use when testing welders for pipe temps , My son rode his 700xx up a hill (approx 110 ft and 60 degrees) the temps measured 4 inches from the block were as follows first run temp. 911 degress #2-935 degrees #3- 878 degrees Ok a wrapped header with him riding on my wifes 700xx #1-555 degress, #2-745 degrees #3-777 degrees once again both measured at approx the same place maybe it helps everyone maybe not but i know its hot hot hot on the leg.

Yeah, totally normal... it does have it's good points though. Will cook hot dogs without the need for a campfire. Great if you want to heat up your lunch on the trail. At night, you don't need a night light.

Glowing green? You sure that's not the drugs you were taking? Or was it on St. Pats Day and your quad just wanted to be Irish for the day?

saying it will run too lean with the spark arrestor and filter lid removed, wouldnt that mean that fitting a slip-on with a filter lid would mean it would be alot leaner?

So...I was riding the other night and noticed that within about 2 or 3 min of it running, the header pipe started glowing red. I have a FMF slip on with the stock header pipe and switched to a UNI air filter.

Just wondering if anyone else has their header pipe get this hot and start to glow so quickly of if I have a problem.

I have not messed with the fuel injection...I don't have a EFI programmer.

Any feeback on this issue would be appreciated.

It is common for header pipes to glow. How quick and intense is the question. Sounds like you are lean from your set-up. I would get a programmer and get it dialed in.
