I think it's a good bet that the blued area is the one where the reducer extends to  :o

That's gorgeous!  I love that blue colour.

Is that with a carburetor or with fuel injection?
If it is with fuel injection, do you have an O2 sensor on the exhaust pipe?

I haven't seen it. I just read from users that it was there. It may or may not be the same as the earlier header from H.
Anyway. If there is some length inside the header that continues the same port exit diameter for some length, that would be a good thing for tq.

I thought hard about this, and I remember noticing that the starting of the new header pipe's ID? did match the exit diameter of the port, before I installed it.

No, no!!  This is a Royal Enfield we're talking about.  Your contribution to the greater good is to keep installing stuff until it doesn't work any more.  Every RE owner knows this.   ;)

Seems like yours is running good also. Does your commute involve a lot of start/stops, short trips?

That looks like a nice healthy burn there.  :)

On winter there are  short trips and the  engine does not reach the optimum operating temperature.

......... Just wanted to ask what you guys/girls think of the condition of the exhaust valve, as shown in attached pictures........

That's exactly what mine looked like three thousand miles ago, after running the stock exhaust for the first 2500 miles.

I havn't looked at it since....  but, B5 is still running  8)
