i have 99 f4 with 25k when i bought it it was very quite but after a while the valve train became chattery so I had the valves adjusted and put a new cct in and it helped now it has been 2 month and now when the bike gets warm I get a tapping sound in the top end please help thanks

 

I'm guessing the new CCT wasn't the manual one?

Around how many rpm do you hear it?

 

low rpm and at high it is vary noisyI did not put a manual cct in factory replacement
