I had a 2004 Cbr600rr in 2006. I did every bolt on but no tune, had it for 3 years. Now fast forward- I got my second cbr exactly a year ago. 2009 with 8000 miles. So, the bike is ~17 years old. I also have done every bolt on, sprockets etc. New power 6s. No tune. The previous owner did not say he did any maintenance on the bike. Should I replace plugs, coolant, bearings (front, rear), and steering bearing to make it feel “newish” again? For some reason I keep comparing it to my first Cbr which was essentially new and saying “it could be smoother” steering wise, etc. Anyways- let me have it or be honest with your feedback. Much obliged
