I recently bought a used 2015 FJ09 with 11,500 miles on it. Bike runs and sounds great. Today I called Yamaha USA and asked them to run the VIN for me. I was told that there is a Tech Service Bulletin regarding the CCT. It says that it should be replaced if making noise. With the mileage on the bike and it not making any noise I am wondering if I should see if the dealer will change it or should I just not worry since it appears the bike is fine.
