Hello everyone, I have a 2014 Cb650f with 72k km on it. I am planning to get major service that includes:
Oil pump
Camshaft tensioner
Camshaft chain
Spark plugs
Air and oil filter
Oil change.
Valve adjustment and clearence
Bike runs and sounds fine. Do you guys advice anything else to be checked or replaced?

Unless the cam chain and oil pump are called out for a maint interval in the service manual I’d simply test, or measure in the case of the cam chain, to be sure both are in spec. 72k km is only 45k miles, both items should have much more life left in them, probably double.

Start with all fluids (I do not see coolant or brake fluid in your list), all filters, plugs, then be sure chain, sprockets and tires are in good shape and go from there as needed.

Your bigger issue right now is age more than the miles. Everything is 13+ years old so radiator hoses and brake lines should be looked at due to age. I’d also look at any vacuum hoses for cracks.
