Engine Noise, NOT CCT, slides??

Engine Noise, NOT CCT, slides??
Got a 98' with 25K miles about a week ago. At idle there is a loud ticking comin from the top of the head, at about 4K revs it goes away. Gets slightly quieter when its warmed up.
Really doubt its ccts, I was thinkin either valves or carbs?
I dont know anything about twins, this is my first. My old cbr just had loud valves. My pops thinks is just rocker arms?? Do hawks have rocker arms?? Or am I just being paranoid?
ONE MORE THING. DONT REPLACE YOUR CCTS UNLESS U DO IT RIGHT.

Yeah, I wondered about this when I got my SH. Doesn't really sound like a cam chain slapping against metal, kind of like a fast "poof" sound under the tank? I just figured it's the carbs since it is most proficient around 2-3k rpm. I've searched and I think it's just one of the bikes quirks.

i would put money down that it is your valves!! that matches perfect to others discriptions of valve clearance being off. i have never experienced it because i have kept my valves adjusted.
so what do you mean dont install your new CCT unless you do it right? explain! im about to put one in on mine before a long trip. i have 22,000 miles on my 98

Doubt is a dangerous thing if she goes poof cause you ignored it.
Twins are the same as most other late model in-line fours as far as how CCT and valves work and adjust. Just double the cames and CCT's of a 4 banger.
VTR doesn't have Rockers, reference the on-line parts fiche below. The cams (#3,4,5, or 6) sit on top of a bucket/shim type of arrangement and the cam lobe pushes directly down on the bucket (#9) that sets ontop of the shim (#16) that sits on top of the valve (#7 or 8). You adjust by changing shim thickness.

I took it to honda and they told me i was being paranoid. They said that the Hawks should make noise. Something about the valves being real tight from the factory especially the exhaust valves. Anyways, its good if u hear them. If u dont is when u should worry.

I don't know about that. I have nearly 30 K on mine and each time i checked them they have been in spec..
First check was at 800 miles , last check was a couple of months ago

Yeah, don't freak out, but still check the clearances, the front is a bit of a PITA, but it's doable.
I did mine this spring, might wanna check it out
