The reported symptoms might result from fuel starvation due to inadequate fuel tank venting.
If not already done, would test ride with the fuel tank cap ajar (i.e., not snapped down), which assures ample venting, and to rule out inadequate fuel tank venting as a possible cause of the bogging when accelerating.
A similar cause could be crud of some sort (such as paint over-spray or whatever) suspended inside the fuel tank that collects around and clogs the filter screen on the petcock intake that protrudes up inside the tank.
The better fuel tank "flush" is imo a
fast flush which entails tank removal in order to turn the tank upside down and fast dump out the contents through the filler hole.
There are also additional causes of fuel starvation, such as petcock malfunction, clogged petcock, clogged or pinched fuel line, water in the tank, etc.
Petcock positions --
ON relies on vacuum to allow fuel from the tank's main "upper" section.
RES relies on vacuum to allow fuel from the tank's reserve "lower" section.
PRI (Prime) doesn't need any vacuum, and allows gravity flow of all fuel from the tank through the petcock.
Good Fortune!
