Most 4 strokes exhausts will glow up around the head.My YFZ and my Z-400 have done it since day one.That is not to say that there couldn't be a problem but, I have seen this alot on 4-strokes...............

The red head pipe is normal. Could you be more specific about what it sounds like in fifth gear? Does it only sound like that in fifth?
