I know theres been alot of Questions about this. But last night was by far the reddest I have ever seen my header. I was riding in the snow and there was alot of high revving and tire spinning (no air on the header), lol. I'm Running...

Rossier
UNI filter
CRF needle on the 3rd clip
185 main
50 pilot
Open airbox
AF screw at 2 1/2

Should I try a 52 pilot? I heard this will fix the problem...?

It's normal at night. They get red in the daytime too, it's just not as noticable. I wouldn't worry about it.

First several inches of the pipe WILL glow at night.

Like previously stated, you don't notice this during the daytime b/c you can't see it.

BUT...if you think you're lean. Do a plug chop and see how she's runnin. And, if you're not popping on decel, I would leave the pilot alone....not very many people run a 52 pilot.

Thats another thing, is does kinda gargle on Decel, no backfiring or anything like that though

I'll try putting it on the 4th clip, getting to the 450r carb is such a PITA!!

I went with a fatter slow jet.My glowing pipe never came back.And it gave me a little more on bottom end too.

I agree with that, i have worked on both and the 300 is a big PIA but i think the 450r spark plug frustrates me more to get out.

Also i started my quad a few days ago to go riding and my pipe started to glow and stuff, but i read this thread a few days before riding and was like oo i guess its normal due to the cold weather and stuff......It turned out i F*cked up pretty bad and rode for a whole day with no jet in my carb because it fell out. I havent started it up yet with my bigger jet for the cold weather installed, and i have been crapping myself that i screwed up my engine work. Do you think it would have screwed it up for riding 3 hours like that?

i dont think so. You were just getting way too much gas, surprise you were able to ride.

Also, i have no problem getting the 450 spark plug out without removing any plastic.

450r spark u need to use your tool kit tools.I have no problem without removing the plastics too.

turn the timing screw ( right above the header) counter clockwise till the bike stops glowing and you can turn the screw till you think the bike sounds just right!!!

honda sent a "WRENCH" paper like usual to there techs explaining that if a customer complains about a glowing header to explain to them that it is completly normal.

i aswell agree that the pipe should glow the few inches but should never glow towards the end.

True, but at the bottom of that letter it explains how to fix it. They just don't want to have to fine tune every bike they sell.

there explanantion as i remember was a quad running really lean, but that would result in the header glowing deep into the header and i would rejet if this is a issue with anyones bike. also they said it was because the light weight alloy they used. but im not header expert

I'm a honda fan for years.I really think honda is trying to out of helping out there custumers for there own mistakes.If a peice of metal getting cherry red there is a problem somewhere and it's not the custumer.

Posted by: 450rJam

when the temp drops it changes the air fuel ratio much like altitude or humidity.

if its a little lean at 70 degrees it will really lean out at 20 degrees.
alot of winter riders rejet for the cold.

better rich than lean for reliability.
