Question about 2004 Honda CBR 1000 RR Fireblade

Honda CBR 1000 -87 slacky oil pump chain

Some time ago I tried to find out what could cause rattling noise when
engine idling, I was told to suspect camchain/tensioner or clutch. I took
the engine out from frame, removed oil pan and it appears that oil pump
chain has really lot of free play, it can touch the edges.
I did not find chainlock from chain, it seems that original chain has been
installed round crankshaft before attach crankshaft to engine. Is there
such replacement chains (with lock) available that could be installed
without removing crankshaft ?

Possibly but there should be a lock on the chain if think there has to be a way to adjust it id re look the chain and if not id get the dimentions of the chain and look for one on the net but make sure this one has a lock unless it will rattle so much that the lock will fail and the cain will come undone and that could cause one hell of a wreck or a ride bud

The oil pumps chain is driven by a sprocket behind the clutch basket.All you have to do is remove the clutch basket and the sprocket will come out really easy.

My 2002 St 1100 when i rev it at about 2000 reves it sounds like a loose chain in the engin, it goes out of it above and below 2000 reves

This type of problem is hard to diagnose without hearing the actual sound in person, but it's possible you're hearing the oil pump chain.

Does it sound like the rattling is coming from the front, bottom of the engine?

There is a chain under the clutch basket that drives the oil pump. Over time, the chain stretches and gets loose, requiring replacement. It goes without saying that failure of this chain will cause catastrophic damage to your engine, so it should be checked if it sounds like it's on its way out.

Here is a link to info on accessing the oil pump chain on an ST1100:

I am have just purchased a cbr 600 ft and there is a slight rattle from the engine which a mechanic has told me is something to do with the cam chain tensioner. The last cam chain was put in about 12k ago...

They should last a bit longer than 12k, but wear in the guides can also make then rattle a litttle sooner. Sometimes the tensioner can wear premiturely
The bad news, the more it rattles, the more chance of damage, On some bikes I have seen the cam chain rattle through the side of the barrell until it leaves a hole and leaks oil, If the chain breaks, the pistons usually bend most of the valves.
Basic mechanical knowledge is also going to need the help of a manual. or at least mark the cams and take a few photos to reset the valve timing, or you next problem will be like many requests on this site"how do I set the valve timing"

Clunks when starts rattles at low revs

There is three chains inside the engine that stretch due to high milage. One is for the starter, one for the cams, and one for the oil pump. I replaced these for a friends bike and it quieted it down.

Rattling noise from valves need free manual to trouble shoot

If it only rattles under load (when riding, not when parked up) then it will probably be your cam chain tensioner, a cheap and easy part to replace.

P.s remember to prime the tensioner by subermersing it in fresh oil then pumping it until all bubbles have disappeard.

Hi,when the engine is cold i hear a noise from the right bottom side of the engine,if i rev it to 2000rpm and up it stops,also when i push the clutch the noise stops.when the bike gets the idle tamberature...

Hi there, what you have is a very common problem called Cluthe Rattle.... I say problem but its not really, unless it is really really load its not going to cause you a problem, might be worth whipping the clutch cover off on the next oil change and as long as everything looks like its done upo it should be fine.. when the cover is off iff you grab the clutch basket in your hand and try to rotate it forwards and backwards you will probably be able to replicate the noise your hearing just slower....

chance is something is loose and as the engine warms up it takes up the slack due to the metals expanding, try to track the location of the noise. this is an older bike and internal components may be worn out, and until oil gets there and engine warms up this would be normal. try using oil for high milage engines and some slick 50 treatment if you dont find anything loose. (like engine mounts, pipe mounts etc)

Rattling noise from engine sometimes . mostly when choke just turned off or slowing to stop early on . not as bad when done a few miles . 15000 miles on clock . suspect cam chain tensioners ?

Its probably the automatic cam chain tensioner. Honda told me to ignore the noise because nothing bad is happening. My bike shop said I should replace it with a manual tensioner. I have 15300 miles and will leave it be.

The motor has a rattle when first cranked...after 10 minutes its not as loud...above 1500 rpms you cannot hear it... bike has 33,000 miles on it and is completely stock from factory... is it time for a...

I've got a 1995 cbr600 and it had the samr problem- it's a well known fault with hondas- it's probably the cam chain tensioner. It works off oil pressure so sounds like a tin full of marbles until the bike warms up. The best solution, if you can't live with the noise is a manual cam chain tensioner. APE make them and it stopped the noise on my bike as soon as it was fitted. I'm not sure if you can get one for your bike but a little googleing should tell you.
