i've had my '00 F4 for about 2 or 3 weeks now and im starting to hear a strange noise. i can only hear it when someone else is driving the bike, my dad said he could faintly hear it when he was on it. it happens when you start from a stop and are accelerating through first, this tinkling/rattling sound comes out. the best way id describe it is like placing a small nut or bolt in an aluminum can and shaking it around. does anyone have an idea as to what this could be or how to fix it? thanks!

 

Hey,
It could be alot of things:
Low on oil
loose parts/fairing
bad rear shock/strut
any bearing
Engine somewhere needs adjustment

Like everyone always tells me, KISS (keep it simple stupid)
do the easiest first, check the oil then go from there. Sorry I can give more spacific help, but I am not that long into
these bikes and havent delt with alot of this stuff. Good luck!

 

my dad thought it might be something to do with the chain? like it needs lubricant or somethin?

 

The only way I could see the chain making that noise is if it was extremely loose, hitting agains the chain guard. I am not even sure if your bike has a metal chain guard. If you think its that, spray some WD-40 on that puppy and see if it goes away, Im betting it wont. Good luck!

 

It sounds like a cam chain tensioner.

I will second the idea about the camchain tensioner..they are known for failures in CBR600's

 

how can i fix this camchain tensioner?

 

I have the same problem with my 02 f4i. Right at about 5500RPM up to about 6200RPM i get this weird rattling noise. Its perfectly fine in lower and higher revs, but it kind of confuses me. I only have 4200 Miles on the bike and i dont think it should be doing this.

 

yea, only 6500 on mine. almost wonder if i should take it to a honda shop to look over everything

 

well i feel retarded. i took it to a honda dealership and the guy said the only rattling sound he could hear was the chain and thats how its supposed to sound, oops
