how hot does the hottest part of the bike get?

JIBTEXHNKA · 06-25-2008, 07:14 AM

above 451 F, possibly? probably not anywhere close?

The hottest part is probably right at the bend in the top of the headers. I've never measured it though.

Jonathan is probably right, I accidentally touched that part once (don't ask) and my hand had moved itself back before I even knew what had happened. That was how fast my skin and muscles responded to the heat. And in the 1 second it took me to bring my finger up so I could see it, the blister was already there. It was HOT, and I felt like an idiot afterward for not wearing my work gloves. This happened about 2 weeks ago and I still have the blister on my finger, though it doesn't hurt anymore, it is just healing/going away, still hard cracked skin though.

I have touched many a hot car part, even a cars cat which is one of the hotter places, and it didn't burn nearly as much as that pipe right at the engine. God that was hot, my finger is starting to hurt just thinking about it again.

i've got a similiar burn from the muffler on my elbow... just barely touched it but it blistered up nicely. don't think it's as bad as yours... but i doubt the end of the exhaust is a whole lot cooler than the beginning (for lack of a technical term which i'm sure exists).

At least by the time the gases have reached the end of the muffler they have had time to cool down some. The metal at the be bend in the header is in direct contact with the explosive gases right out of the cylinder.

true... i just doubt your skin really cares all that much about the difference.

**jonathan180iq** · 06-25-2008, 04:45 PM

word..

I'd also bet it's hotter than 451

I did the exact same thing a couple of weeks ago while screwing around with my highway bars. It really didn't hurt when it happened, and the blister was more like a really hard callus for the first day or two. After that, it broke open and bled and all kinds of nasty stuff. I've had numerous muffler burns and they don't compare at all with the burn from the header.

Yeah, at the instant it happened, i didn't even feel it, it was a few seconds later when i stood up and started to walk away that it felt like my finger was still touching the exhaust. And it seemed to hurt everywhere else on my finger except at the actual burn.

I know that this was mainly Started as a motorcycle related topic but with everyone chiming in on exhaust burns, I

thought I would give you guy's a good one. I work on alot of chainsaws for a living and one day I had been trying and

trying to get one adjusted right and I had it running for about 10 minutes straight trying to get it adjusted right, finally

turned it off set it on my work table, proceeded to sit down on my stool, fell forward, put my hand out and grabbed

nothing but chainsaw muffler. Had a burn in the palm of my hand shaped like the bolt pattern and shape of a

husqvarna chainsaw muffler for like a month.javascript:emoticon(':curse')
