Depends on what you consider "issues". The load induced by a smaller rear sprocket will mean more stress on the clutch, and possibly engine issues with the lugging. Same thing applies to driving a car by upshifting at very low RPMs: you can get buildup of fuel and carbon, necessitating some high RPM time to burn that off.
This may not be a problem with this type of bike, as high RPMs are de rigeur during normal operations. I also assume the Honda engineers went through that process, changing sprockets and ratios until they achieved a nice balance of performance, economy, and comfort/noise. A conservative method might be to change the ratio by about 10% and see how that goes. Beware of More's Law: If enough's good, then more's better.
