A – the model year of your FJR
-->FJR 2007 ABS
B – the number of miles on your FJR when the cam chain noise became apparent
-->43500 miles
C – what action did you take, i.e., replace the CCT yourself, have the dealer do the work, ignore the noise, etc., and at what mileage
-->I have replace the CCT with a friend
D – did replacing the CCT eliminate the problem, i.e., the chain noise
-->Yes, after replace the CCT, no more noise
E – was the problem diagnosed by a dealer and if so, dealer name and specifics
--> it's strongly advise by YAMAHA MOTOR FRANCE (YMF) to change it on FJR without the CCT reference 1MC-12210-00 (with a green dot) before 45000 miles for a normal utilisation, and for cops, it's every 25000 miles. THe two first generation of CCT ,5JW-12210-10 with the blue dot, and 5JW-12210-00 without painting dot are more delicate.
In europe the new CCT appear in 2009
F – were there any problems related to the CCT failure, i.e., cylinder head damage/engine replacement
--> N / A, changement before all problems
G – if the repair/replacement was performed by a dealer, how many days
--> Repair by myself, and a friend in 2 hours
H – paid for by Yamaha or not/under conventional warranty or Y.E.S
--> for YMF, it's a wearing part
I – have you replaced your CCT more than once, including how many times, mileage at replacements
--> Just once
J – did the chain noise begin randomly, or did it begin following valve adjustment, where the CCT needed to be de-tensioned to facilitate cam removal
--> It start randomly.
K - if you are needing to change your CCT are you confident Yamaha's redesign is sufficient or are you considering replacement with a manual aftermarket design
--> Yes, the new spring of the new CCT is realy stronger. with a more turn, and a range shorter.
