Hi all, Reading this has made me feel a load better. I picked up a F4 a few weeks back and after a bit of riding and getting used to it i noticed this small ticking sound. Bike was over due it 16k service (wish i checked that when i payed for it) But its done now buy a great local garage and he had a really good look and could not find any problem when he had the bike in bits and said the same, just one of those things. So back to enjoying every second of the bike. Any tips on after-market exhausts? What about Delkavec?
