Yes, you do need to adjust to the higher revs and that takes a little adjustment. I cannot comment on bikes as I have a scooter (which sounds like an angry hair dryer) but I once did have a Honda S2000 (sports car). That thing did not come alive till 5000rpm and went all the way to 9000rpm screaming like a banshee. Once I got over the initial shock and realization the engine was not about to explode it became music to my ears. If you do not grow to love that sound then you might just be a cruiser guy.
