I'll try to keep this simple. Like me.
Reducing the size (number of teeth) on the front sprocket lowers the gearing, which means higher engine revs for a given road speed but quicker acceleration. Also, it will increase fuel consumption at cruise speeds.
You have a larger front sprocket, though, which on its own would raise the gearing and give the opposite effects to the above.
However, you also have a larger rear sprocket than standard which changes things again. Stay with me.
Fitting a larger rear sprocket (more teeth) lowers the gearing, the same as fitting a smaller front sprocket. In your case, the PO has done a bit of each.
The extra tooth on the front sprocket has a greater overall effect than the single extra tooth on the rear, meaning you bike is higher geared than stock.
In theory, you have a little less acceleration on tap but cruise rpm for a given speed will be lower, hence marginally better fuel economy.
Usually if owners change the gearing on a Gen 1, then drop a tooth at the front - and possibly go up one or two in the rear - to make bike more responsive.
I've never tried lowered gearing on mine as I'm perfectly content with how it performs on stock cogs.
