Coolant change. Is all this necessary?

I have a 2007 Honda VT750C shadow aero.

I am overdue for coolant flush and change. I bought a aftermarket repair book that is helpful in many ways but the info I see on the coolant flush is minimal . It refers to gas tank removal, speedometer removal, various other steps before the flush process. I went to Youtube to see if any info would help and I cant seem to find anything detailed.

Does any one know of any detailed instructions on this? If its not necessary to remove the speedomter(tank mounted) and the tank, it would seem a little less confusing.

Any ideas or help would be appreciated.
