Hey, Has anyone tried ceramic coating the exhaust on any of these bikes before? Did it help with the burning legs and hot plums? Was out riding the other day and literally boiled my legs to a point they swelled and then was to painful to walk on for a day…. Not a fan of the heat wrap stuff And was curious if ceramic coating worked. Thanks for any info…
Ceramic coating might drop it down by a couple of degrees at the most. It really is more cosmetic then anything else.
50,000 miles is impressive stuff sir. You must have magic legs! I need some of those… mine and my mates do exactly the same. It’s like a torture procedure form Henry the VIII.
Lol, no magic legs and ridden in all weathers and for all sorths of things, commuting to London, euro trips, trackdays .... maybe just go faster ;-)
We've been using a coating from these people on Formula 1 exhausts for a long time. https://zircotec.com/ It does reduce the heat loss quite a bit. Obviously the heat has to go somewhere so components further down the exhaust, like silencers, will get hotter. It's an off white coating. I like the look of it when it's new but, as it has a texture akin to 100 grit sand paper, it attracts the dirt like nothing else. Once dirty, it stays dirty.
I suppose this might be an issue in traffic or city riding... but my 996 runs very cool... I wear proper gear mind... so cannot comment on your plums ;-P Compared to the SFV4 or the 1198 or, dare i say it, the Desmo, the 996 is a "breeze" Sounds like it needs more airflow ?
Funny you say that as I had a vintage gentleman come up to me and asked how I was getting on with it? he had a 916 for 20 years, I said about the heat problem and he laughed and said “ Lad you ain’t going hard enough!”
I’m not to sure really, it could well be just not enough air flow around. I’m not long past so not going at to hard and suppose couple that with predominantly country roads could just be that.
Interesting, thank you. So potentially could damage the silencers with in time maybe. I suppose it is that problem of eliminate one issue then it’s passed down. Food for thought though. Cheers
Here is a picture of a MV Agusta F4 exhaust that was wrapped to keep the heat away from the belly pan etc. The retained heat completely destroyed it. It's always preferable to protect other components from the generated heat. Perhaps wrap your legs and balls
That’s interesting thank you. always best to see people’s experiences to see if it’s worth while. Maybe I’ll ceramic coat myself from the waste down!
Over the last 26 years I have been riding (and still do) a 750F4 (36,000 miles) a 748sps (34,000 miles) and a 1098(38,000 miles) each one is hot round the nether regions but never uncomfortable. Swollen legs and inability to walk what can I say other than I can't believe the bike caused that
Surprising to me as well. I have been riding 916s, 998, and a 996 a few times and never had any of them running hot like that. On the other hand, my 2011 848evo, and later, my 2018 939 Supersport were both horrible frying pans… I recently helped a friend whose 996 was running hot as well. My assumption was that it was running lean. So we checked/adjusted the valve lashes and then reset TPS, synchro and finally set the %CO. I found an AFR that was nearing 20… Reset it down to 12.8 on the horizontal cylinder and 12.4 the vertical. The bike doesn’t run hot at all anymore. I would check how the mixture is set.
Hmm that could be what’s making it kick of heat like that. As a reference, normal riding open roads it sits on the temp gauge around just under the 80c. It will creep up to 80c slow moving but stationary for short period that will creep up to just under 100c before fans kick in. Cheers
