Many ICE motorcyclists I know regard this as a bs stealership tax, but I can attest to the importance of that first service.
Before taking my last two new bikes in for that first service, I loosened one motormount bolt and set the rear wheel slightly askew with the chain-tension axle adjusters, and let about 10PSI out of a tire. Both times, all of my traps were found and corrected.
I still like to do the initial service myself after they're done--remove all of the fasteners and apply the correct level threadlock, carefully Honda Spray* and clean every surface and get everything perfect. I'm not a dealership mechanic, but I do like working on my own bikes. It's a satisfying feeling to roll down the road knowing you have perfected every valve clearance, every spoke tensioned, and every fastener tightened to the correct torque by your own hand.
*And in case it hasn't already been mentioned in this forum, Honda's polish spray is great, great stuff for keeping your steed shiny, pretty and protected. I gave up on Honda motorcycles after my abysmal experience with the VTR1000F Superhawk, but still slink sheepishly into the dealership for Honda spray every few months.
