Crapping Myself

Hi guys,
been out on the RC a few times recently, performed gr8. Yesterday, I started it up (cold) and could hear a ticking noise, (not a tapping, but ticking). Only way I can describe it is it very close to the ticking noise that a car manifold makes then its perhaps got a slight crack in it.

The RC is still performing great, but Im crapping myself that its a head/top end issue.

Gonna try putting a little more oil in as Ive seen one of these where the issue was down to oil starvation.

If it turns out that the valves need checked (they havent been done while Ive had the bike b4 you ask), then ill need to put it in my garage for the rest of the year as Ive just moved home and am now skint, for pretty much the rest of the year.

Any advice, or things I could check?

Check all your exhaust header pipe joints for leaks. Could also be a failed exhaust gasket at the head.

Check for an exhaust leak, especially at the heads and at any part of the exhaust where there are joints. Some exhaust leaks also sound like ticking.

Just throwing this out there, but double check valve retainers. been down that road myself. Verify cylinder pressure to validate opening it up.

Ok, Ill look over the exhaust, but valve retainers and checking cylinder pressure is out of my mechanical capability.

I should have added a disclaimer that your bike would barely run properly if a valve was not opening/closing correctly, especially an intake valve.

Ok, topped up the oil a tad, trhen took the RC out with my bro (on his NC30) for a couple of hours. Stopped halfway for a coffee, fired up the enging and we both listened (as by this point we had our helmets off) sounded fine, no issues. Maybe its just when its cold. Getting paraniod about the noise, but will keep an ear out for it and will keep you updated.

TBH some parts of the exhaust and the headers are starting to look pretty tired, so could be that.

either way Ill keep you guys posted.

I can hear a ticking on mine, but it started when I was trying to bend the exhaust back into position after it fell over. Just assuming it is an exhaust leak at a joint. My old CBR had a going bad CCT for 20,000 miles and never gave me an issue. I have faith in Honda.

I had a little look at mine again, On startup you can see a very spall amount of exhaust smoke excaping from the rear exhaust flange (where it joins the engine)

Otherwise its running fine.
