Valve ticking and other problems
Hi everybody, this is my first post and its kind of a doozy so here goes. I picked up a f4i on craigslist for a good price but it has an issue I can't figure out. It seems to have an exhaust valve ticking at any temperature but it is louder when the engine is colder. Here is a video of the sound with my GF on my bike LOL.
YouTube - CBR600 F4i ticking Maybe you guys can help me figure this out because I'm new to bikes and need some help. Also I checked for engine codes and it throws a code 1 and 9 which are the map sensor and iat sensor. I will take the tank off tomorrow and check the connections. Any help would be appreciated. |
first thing Id be doing is pulling the valvecover off and pulling the cams to check valves...
|
Any power loss, or lack of power for that matter? start with the easy stuff. maybe unseated spark plug?
|
I do not hear any ticking noises.. O wait.. got distracted
|
If you already suspect of an exhaust leak, check that first.
But it sounds way too metalic to me... Check exhaust 1st, then timing, valves and cctl |
Thanks for all the help. today is my day off and it just happens to be raining and I don't have a covered dry spot to work on the bike. I'll have to wait for another day
|
Definitely sounds like bad valve tap or rod knock. Hopefully not rod knock. How many miles are on the bike? Did the seller disclose any info on the tapping?
|
not to be a buzz kill or anything and my biek does it too but can you hear that buzzing noise anyone? isnt that the cctl gone bad? my bike does it to so i want to know. It sounds like a "can of bees" or is that a honda thing?
|
doesnt sound like cctl to me. Usually cctl is consistent around 4-5k. At idle like that, Id be suspicious of the valves. Id be checking clearances. Just checking isnt too bad of a DIY job, having to adjust is a pain the ass though since you have to remove the cams.
Hell if you lived anywhere near Charlotte, NC, I offer free f4i service! LOL all other bikes work is done by donation only LOL |
I have the CCT noise at 5-6 k. but at idle it does not sound like yours. So I suspect its the valves as well.

doesn't sound like CCT, more like valves. does it go away or get louder under load?
