I have a full Bil Balance pipe and it glows red in the front as well. Jetted to perfection. Doesn't cause me any problems.

If you take a stock motor and make it flow more air (taking the baffle out) without giving it more fuel its obviously going to run lean, which means run hotter.

You'll get more power, and run cooler, if you simply go up a couple jet sizes on the main (with the baffle out).

As for a full exhaust, i've never had a YFZ. So i couldn't help you there.
