Has it been run low on oil at any point?

Have the valves been checked recently?

It is also possible the cam chain tensioner isn't working properly, but it's hard to say.

 

[aruninchoor]

no the oil changing has done properly, mechanic told me it might be Valve clearance or tensor problem. but just want to make sure if someone has this same issue.

The sound is definitely something to do with the valve train. The first thing to check is the Cam Chain Tensioner. They are pretty cheap so I would just buy a new one test it out. Past that it could just be the valve clearance could be too much.

Has this sound started all of a sudden or has it gradually gotten louder?

 

[aruninchoor]

gradually got louder i guess,i was not aware of this sound unitil i hear my friends bike sound,which is smooth.thanks for your tip

How many km's on the bike?

Source of the noise could be the cam chain tensioner, as others have suggested. But I'd also have the valve clearance checked, and adjusted if clearance is found out of specification.

 

[aruninchoor]

bike has almost completed 27000km on odo,is this normal?

 

[Schroeder]

Some people have had problems with the cam chain tensioners and some early models had a tendency to have their valve clearance out of specs though the latter one should have been corrected on the very first service after 1000km.

 

[aruninchoor]

my cbr is 2014 version,one mechanic told me the problem is with tensioner and maybe shim,hope fixing this will sole the problem.thanks

I'd say that it is definitely due for a valve clearance inspection.

 

[aruninchoor]

ok thanks.i will get the bike checked Tomorrow,
one more thing is at low throttle their is missing feeling,after that no problem.. any idea what is the problem?

Easy thing to try would be to add a strong fuel system cleaner like Techron Concentrate (1oz per gal) to a full tank or 2.

That will clean the injector and also the intake valves and combustion chamber of deposits which can build-up and cause detonation and other issues.

I run it every year in the cycles after running my storage gas (with stabilizer) just to make sure the system stays clean. Also run it in each vehicle after the winter season when there is an overly rich mixture due to cold temps.

I'm big on preventative maintenance.

 

[aruninchoor]

thanks,i have fixed the sound,and as you guys said it was shim problem..but still their is a slight tik tik sound i can hear???

 

[cbrlocal]

Probably the tensioner. Factory ones are noisy to begin with, then as they age they knock more and more. Mine got so bad I thought I had a bearing going. Replaced with some Lowes hardware and made it a manual adjustment; never had another issue.

 

[aruninchoor]

it is not annoying but still i can hear a slight tik tik sound,and cant hear while riding

You can't hear the tensioner when riding. At idle you can hear it, and if bad enough you can feel it chatter in the handlebars.

 

[aruninchoor]

ok,is it ok to ride,its not a major problem? right?

Finally, someone from past 2015 to talk about this [email protected]#ing engine rattle... hope you're talking about the bb's in a can sound like as you accelerate in gear.
