Am I going to fry my valves with this exhaust setup??

Hi guys,
I wrapped my header pipe with fiberglass cloth and machined myself a end plate with a one inch hole (better airflow...) on my supertrapp exposed disc can.

Am I paranoid, or is it possible to burn the valves with this setup. I guess I thought this might be a problem because my dad told me about when he was in high school, and everyone dumped their exhaust without hardly any muffler action. He said the noise produced was out of this world, but the teenagers would burn up thier valves, because the hot air inside the cylinder meets the cold air outside the cylinder, and warpage to the valve occurs. :shock:

Is this going to be a problem for me?

Take care!!!

I have no ideal !!!!!
But race cars run open headers. But they change motors often.

I am not an expert by any means on this, but here is my thinking on this.

You wrapped the headers, which should keep the heat in. You still have the full length of the exhaust and I assume the baffling inside also you just opened up the end?

So I would doubt that any cold air would get down to the exhuast port of the bike...Doug

The best part is since I have a 14t countersprocket and this exhaust, coupled with my .030 washer carb shim, wheelies w/o clutch are hard NOT to do!

The pipes that warped the valves/head were cut pretty short, if your system is as long as the stock one the cold air shouldnt 'rush' in that far.
