Exhaust Wrap

[lawson17]

Hi,

Has anyone used exhaust wrap before? Its for my SV trackbike, I got some new fairings for it, and they are a bit of a pain to fit. The catchment tray or bellypan, fouls the exhaust pipework under the engine.

If I stick some exhaust wrap in the bottom of the tray do you think it would stop the bodywork getting too hot?

Thanks in advance for any help.:-D

Yes it will.

I wrapped my exhaust last year and it worked fine until I did a few wet races. Then it starts to get a bit shabby. This year i'm using some heat shield (same stuff from underneath the tank) and placing it between the downpipe and fairings.

Great,

Thanks Sideshow. I'll get wrapping today. :D

Also good stuff for maintaining temps and gas velocities in the headers which can equate to improved exhaust scavenging from the cylinder.

Read that, probably not enough to notice.

I hadn't seen that thread... or ever even visited that site. Some flawed math and arguments there, plus a fair bit of willy wagging.

That info has been around for a 100 years. Whether it produces a noticeable difference is dependant on a lot of things, but in some cases it can be used as a tuning aid. I don't know if the SV is one of those cases.

Aaah... The subtleties of the English language - two possible meanings to YC' words. I only looked at the first three pages of that thread to make the above assessment. Just skipped to the last page and a half and it starts to make a little sense. But still... A link to a forum thread with one guy anecdotally poo-hooing an idea as a definitive reference? The science is sound, results may vary.

mmm i have been thinking of doing it as my exhaust system burt through my bellypan, there are so many wraps, what is best, the narrow stuff or wide, also how much do you need to wrap a full system, do you go all the way up to the exhaust can or stop lowerdown?

[MattCollins]

Narrow tape will wrap tidier around the bends.

they sell it at Demon Tweeks mailorder. Stops the bodywork damage.

On my bike it also protects the Elka race shock from heating up next to the rear exhaust pipe.

[Sideshow#36]

Ah another elka user... awesome shock.

Dont buy it from demon t**ts

I really wish people would stop using them. Overpriced!

Thats true for some kit, but the main advantage is that its not too far from me, and they always have everything I need right there in one store. For bits and bobs they are quite reasonable but on expensive kit they take the pi$$ I agree.

Any other cheap sources for exhaust heat wrap, I need some for my winter service on the bike.

[lawson17]

Thanks for your help people. :D

I got mine from ebay, was a bit cheaper than other places I'd been looking. Theres plenty of choice on there too.

I'm sure someone will be able to advise you on whats good and whats not though.

Yes, or lay some heat proof tape/paint inside the bodywork.

Also good stuff for maintaining temps and gas velocities in the headers which can equate to improved exhaust scavenging from the cylinder.
That depends on the headers though, it won't work on every exhaust you put it on.
