Rattling sound help!
Hi I am new here I thought this site could help me do some troubleshooting.
I bought a 90 cbr 600f with my life savings ($2000) and It seemed to make a quiet rattling noise at low rpm. The noise has gotten louder and it now sounds like a deisel engine. It still starts fine and seems to have power but I don't want to ride it again until i figure this noise out. I live in Banff and there is no mechanic for miles so i was hoping someone here could help me out. I could take a video and put it on Youtube and put the link on here if you think that would help. Thank you!

No need to panic just yet !
The 1000F and 600F's all suffer from camchain problems, so if it still quietens down when warm it should be OK for a while. You can replace it yourself with a bit of knowledge and maybe the manual.
Here's a link
www.blackbears.ru
I think the manual is listed - if not, let me know and I'll look for it.

Thanks for your reply
It doesn't seem to get quiter when warm.The only way I can describe it is like ticking/rattling sound like a deisel vw rabbit. When I rode it last it seemed fine. It backfires a little bit too I didn't notice that before just pops here and there nothing major. Is this normal for an older bike? I am worried about riding it do you think I should stay off it until this gets checked out? Could it be anything else other than that?

Well it does not sound terminal... as you say , a little rough though..
She has got the std cam chain rattles going , that's for sure..
Should be ok to ride though ...
Do know when the cam chain was adjusted lasted ? might be worth a look ?
Has anything else on her been altered ..
eg/ carbs jetted ?

Can't open the vid - I get some message about skimlink or something......aaaaaaaaarrrrrr
Does it backfire when running against compression ? If so my old 1000F does it too, not a problem - if it's backfiring under load, it could be valves need setting, dirty carbs, or just that the camchain is causing the valvetrain to be out of whack.Even just dirty plugs.
Hard to tell from here.
You may wish to ask the boys in the 600F section too

Thanks again
I am only planning on riding this bike for the summer then selling it so hopefully the timing chain holds steady.
Here is another question. Speaking of chains I have a very strange issue with the drive chain. With the bike in neutral I can sometimes move the chain about an inch or so. But when I push the bike so the chain rotates to the other side I can only move the chain like a cm or 2. I can also pull the links off the back sprocket a few millimeters. No wear on sprocket that I can tell. Time for a new chain? How severe is this issue?
This site is so awesome!
What a day and age I live in that allows me to do this amazing.
I love this site thanks again yoiu guys are great.

If you can see no visible wear on the rear sprocket , I would check the front one as well ...
Sounds like the chain at least is near its used by date though..
If you don't ride it like a mad man possessed it should be ok for a while though, but if you sell her , do the right thing and tell the next owner that may not be mechanically inclined about the chain, for gods sake...
No CBR'S are great !! ...we are just proud CBR owners that like helping other get the most from there CBR's
your welcome :-)

Hello 90Hurricane, congratulations on your new bike. My bike has similar issues as well, although I'm changing the CCTL this weekend. Let us know how it goes...
Welcome to CBRF
EDIT: Sorry, just saw the video and yeah, it sounds lousy. Definitely try and give it a good tune-up & see if it doesn't improve. Post your question (with vid) in the "general tech" section to get more more suggestions Good Luck
