Ive had my CBRF3 for over 12thousand kays now, changed the plugs when i first brought it and have changed the oil and filter 3 times. Now comes time for me to admit i cant do much else and assume its time for a "major" service at a mechanic. What should i be getting checked out? I dont want to walk in and say, can i get the "major" service thanks (as being skeptical i can only assume this would mean, please ream me!) Any advice welcome.
