i have a 2003 and it developed a whining noise. i'm going to listen to the motor with a screwdriver to kinda pinpoint the noise. no loss in power, no problems shifting. i'm confused on the replacement of the cam tensioner... if it is just the outer do i just change that one? i'll inspect the inner also, but i dont think i wanna pull the cam case to do the inner. i'm not sure i have the right tools. i know i'm capable of wrenching, just limited with garage space, tools, and i have a small bike lift.
