Its not under extended warranty. I changed out the CCT about 3 months ago because it had been making a bunch of noise. I didn't have any issues re-timing the cams then. The intakes do have some carbon build up. Not a lot but probably more than A bike with 24,000 miles should have.
Does anyone know if its an interference motor? It doesn't really specify in the manual.
