Wrapped the mid pipe on my Arrow exhaust on my GTS.

Why? Not for looks. Not for expectations of performance. Please don't turn this thread in to arguments about this.

Why then? To try and move some of the heat away from the coolant hoses. Once the bike is fully heat soaked at the end of a long day on the road and then get stuck in traffic coming home the temp rises crazy quick at the lights which bugs me.

Only thing to note is that I painted in black with high temp paint before wrapping because it was in really shite condition and was concerned about the wrap holding moisture against it when parked.

My one concern is mud ...

And sand. You never know what that wrap will attract.
Be afraid. Be very afraid.

forest roads are not good for wraps

Not sure I care that much. Wraps are cheap iirc this was aud$15 for a roll that is several times longer than needed.

But i might do a little search for a more robust material than the fibreglass that this is made of. Alternatives might be expensive though.

Whatever material you go with it will trap moisture and cause corrosion
It surprised me because I've never ridden in the wet or Stored the bike outside so I've took it off.

Don't know if you're just protecting the hoses above the pipe or something behind but couldn't ride without these heat shields on my scoot. Without them shoes melt and pants get burned. Just a piece of stainless pipe cut with a standoff. Hose clamp secures them and never seem to loosen up.

interestingly I just saw on the Vespa 946 that it has a heat shield in the area that interests me.

just looked at the parts manual and it doesn't appear to wrap around far enough to protect the cooling fan area of the engine. It's probably only to protect the legs of the rider (or passenger) when their feet are down.

Still interesting that it's only on the 946. Hmm

It looks like they welded on some nuts to the pipe and screwed the shield to it. Like the heat shields on old dirtbikes. You could always have yours facing up to protect your hose.

I'm working this weekend on a friend's plane and here's some more heat shields. These ones are aluminum.

I am tempted to try and make a heat shield

this stuff looks fun. (Might start a new thread)

You aren't worried that adding insulation to the exhaust might increase the head temperature which might cause issues with…. well, you know.

well no I'm not.

wrapping exhausts is a common thing with some engine classes and vehicle types with causing what you fear.

plus with my compulsive monitoring of the temp in C on both my dash and in my ride records (auto always recording) I'll certainly know what the coolant temp is up to all the time.

and the latest tactic of using a shield that will catch some airflow when moving should direct air away from the engine bay altogether (wait for pics on my shield that I'm planning)

Approaching this the other way round, can you insulate the coolant hoses or get thicker ones if you feel they're absorbing more heat than they're shedding?

As for the extra heat shield on the 946, this is also on the Euro 5 Sprint / Primavera (2022 onwards). I'm not sure if this addition is just for the air cooled engines but is part of the changes to reduce emissions.
