I have aftermarket pipes and the OEM #195 jet.
It does struggle above 90 MPH (GPS) but I rarely, rarely go there.
Honda VTX speedometers generally indicate 10% above true speed and odometer indicates about 4% high.
Funny you should mention the speedometer - I have a few of those speed signs to/from work and compared. 10% appears to be spot on.
The correct amount of motorcycles to own is always N+1, N being the current number you own.
