Many are familiar with resin impregnated fiberglass header wrap.... and most that have used it hate it at least a little for the reasons or others I mentioned above.
Good news, I have a new source Im using for wiring sheathing.. They supply the little guy to Aerospace, to Military Air Forces and race car teams with unlimited budgets .
Company is called TechFlex https://www.techflex.com/ and they have a product called Volcano Wrap> https://www.techflex.com/high-temperature/volcano-wrap
VOLCANO WRAP (VW) is made from continuous filament basalt fiber and is engineered for protection from temperatures 1,500°F. When wrapped around exhaust pipes, the unique construction creates attractive and durable finished product.
Volcano Wrap is 25% stronger and provides a 300°F increase in temperature protection over fiberglass wrap. The product is very rugged, and will not exhibit any vibration damage over long periods of use.
The volcanic rock fiber wrap is easy to install and will provide years of protection and good looks.
I have ordered some and some stainless steel bands to install and see if I like it.
I'm sure the "It will rot your pipes" comments will crop up. a response in advance.
I used standard resin impregnated fiberglass header wrap for 4 years on my first VTR, I had those headers ceramic coated later so unwrapped to send in..after unwrapping them, they had no observable damage, corrosion issues at all. Now that's here in the US, in a state that does not treat streets with chemicals except for a few days in the winter months when we might have black ice..Im not riding those few days.
And I ride in a US state that likely sees less raining weather days then many in other US states, or places outside the US. .So that might make a difference in my results vs yours.
...
My Volcano wrap should be here today, and my personal workday, Sunday is coming up fast ...so hopefully it'll get installed then.
My goal is to keep heat away from the radiator hose, and oil cooler, To lessen the radiated heat to the motor and radatores in general.
And on the rear header, keep heat away from the shock and shock linkage.
