• Silent Sport motorcycle heat wrap tape: 10m x 50mm x 2mm• Ideal for insulating, resistant to high temperatures (750C)• Highly flexible to be wrapped around pipes
Hot, hot, hot! Temperatures of up to about 500C can develop on the outside of the exhaust manifold when driving. By way of comparison, the manifold will begin to glow visibly red at 650C. Even though, in most cases, the manifold is cooled by the wind blast, it is still sometimes necessary to provide additional insulation in order, for instance, to prevent the rider and passenger of a motorbike from being burnt by awkwardly positioned manifold pipes. Although the insulating effect of the protection strip does lower the external temperature of the wrapped manifold pipes, and therefore protects against accidental contact burns, the insulation is in no way total, and care is always required!
Newly applied heat protection strip will smoke and smell a bit on the first journey, this does not impair the performance of the material, and soon fades away.
Note, however, the following:
- Chromium exhaust components can be permanently dis-coloured (tarnished) by the high temperatures that develop under the strip.It is possible that the change in the thermal behaviour and the different resonances in the exhaust may cause the carburettor to need readjusting. In extreme cases, or when other components are also involved, the jets may have to be changed. (As a rule a richer mixture needs to be set.)
- If used incorrectly (e.g. if the temperature exceeds 750C for long periods) residues can also be left on the wrapped components, and these can be difficult to remove.
- An exhaust manifold wrapped with heat protection strip can cause the engine to come to operating temperature more quickly. Air-cooled engines can be hotter in operation than before.
