I agree with the smaller logos... maybe even use the logo on the alternator cover as a reference to scale the tank logo. Also, maybe consider removing the grab rail from the rear, see how that looks. It seems to detract from the rear fender line. You would have to run a ground lead to the taillight since it would have to mount to the fiberglass fender. Look at it both ways, with and without, then decide which you like best 'cause you're the one that has to live with it! Keep us posted.
Can't tell from the photo but if the rear turn signals mount to posts on the grab bar there are other options for mounting the turn signals. You could substitute front turn/marker lights that are post mounted to the headlight ear like the early models (just don't hook up the running light lead with rear-facing amber lenses) or find some rear turn signal mounts from a later model that did not mount to the grab bar.
