I recently purchased a Renthal 16 tooth front sprocket for my 2009 FZ1. ..... After fitting I noticed the transmission was noisier and slight vibration in the pegs . After a day or two the Fairing was buzzing and vibrating at different rpms and worse when on the power.
I tried all the usual 'cures' such as greasing all the fairing joints etc, but the buzzing kept returning . Anyway, I noticed that the Renthal sprocket was a lot lighter and also didn't have the rubber cush either side to cushion the links landing on the sprocket....... I managed to source a 16 Tooth sprocket from Yamaha ,(Early R1), with the same weight and cush rubber as the original...... After fitting this the vibration and fairing buzzing disappeared.
I tried to claim my money back for the unusable Renthal but they, (Demon Tweeks ), refused , saying it had been used !......:cuss:
