Ticking... Help please?

Alright everyone. I need a hand trying to find out what is wrong. I know it's a long shot but here we go.
2004 CBR600RR
Hardline slip on
K&N filter
Recently changed oil and spark plugs. Also installed PCV.
Since the recent work done, I have had no issues. Today I put about 250kms on the bike. Was running great. Temperature sat at about 80-85 C. Started riding in the city. Stop, go blah blah. Temps were sitting at about 95-100 C. Started to hear a little ticking noise. Didn't really think anything of it. Until it got louder and the bike jolted. Pulled over and called a tow truck.
So I'm standing here now with a bike that has a nasty tick in the top end that gets louder as the rpms increase.
Help please.

usually when i hear a ticking or knock in the motor on my rmz250 its time for a valve clearance check. more than likely your shims are needing a replacement with something bigger. i know if you have a k&n air filter with a slip on your bike will need to be tuned with a PCV to make it run correctly. so hopefully your pcv is running the correct set up. if not you may have a fuel air ratio incorrect and its throwing a few things off.

just go to a dealer and have them check your valves.

but if anyone else has a better notion on this feel free to speak up.

but this is my best bet.

You can be a fast and highly skilled rider with chicken strips. All that means is you understand the limits of traction and speed as it relates to your cornering ability and road conditions.

Hard to know without more info, if it where me I would post a video. It would help to hear what and where the sounds is coming from and what it sounds like at different rpms from idle and up.

Sounds like tight valve clearance. Could be legit knocking of the piston.
