Cam chain noise on a CBR1100 from 1998 Can this be ajust ? if so where is the bracket on the engine

if its upper noise eg folowers and lifters if they are hydrolic lifters where these replaced are the cams ok if they are manually ajustable tappets these can be ajusted unless the following are goosed again the cams are pitted or mishapen will need new cam shaft the lifter rods are worn or week valve springs
but if they are hydrolic will have to be replaced inc cam shaft hope this makes sence ivan

It can't be adjusted, it's self adjusting with a tentioner. If it makes too much noise, replace the chain and don't forget the guides and tensioner!

Timing Chain & Gears Removal & Installation To Remove:
NOTE: Keep the cam chain away from magnetic fields.
Crankshaft set at TDC marks

1. Turn the crankshaft pulley so its Top Dead Center (TDC) mark (1) lines up with the pointer (2).
2. Raise and support the vehicle.
3. Remove the front tires/wheels. Front undercar splash shield
   
   
4. Remove the front undercar splash shield.
5. Remove the drive belt.
6. Remove the cylinder head cover (See section on Valve Cover).
7. Remove the crankshaft pulley (See section on Crankshaft Damper). CKP sensor and VTC solenoid electrical connectors
   
   
8. Disconnect the Crankshaft Position (CKP) sensor connector (1) and Variable Valve Timing Control (VTC) oil control solenoid valve connector (2).
9. Remove the VTC oil control solenoid valve (See section on VTC Solenoid Valve).
10. Support the engine with a jack and wood block under the oil pan. Ground cable and upper bracket removal
    
    
11. Remove the ground cable (1), and remove the upper bracket (2). Side engine mount bracket removal
    
    
12. Remove the side engine mount bracket. Timing chain cover removal
    
    
13. Remove the timing chain cover bolts both from the front to the block and from the bottom to the oil pan.
14. Remove the timing chain cover.
15. Loosely install the crankshaft pulley. Compress the timing chain auto-tensioner
    
    
16. Turn the crankshaft counterclockwise to compress the auto-tensioner. Lock the timing chain auto-tensioner
    
    
17. Align the holes on the lock (1) and the auto tensioner (2), and then insert a 0.06 inch (1.5 mm) diameter pin (3) into the holes.
18. Turn the crankshaft clockwise to secure the pin. Removal of the timing chain auto-tensioner
    
    
19. Remove the auto-tensioner. Removal of the timing chain guide B
    
    
20. Remove the cam chain guide B. Removal of the timing chain guide A
    
    
21. Remove the cam chain guide A (1) and tensioner arm (2).
22. Remove the cam chain.

hi, it may be timming chain, or gudion bearings, things sound louder in engines. (is your drive chain slack as this is easy to ajust)

It is likely that your noise is coming from either the cam chain or rocker arms. As the engine gets hot, the oil gets alot thinner-especially if the oil is in need of change. This would explain the extra noise when it is hot.

First thing to check is the valve clearances to be sure they are within tolerance.(Intake:003-.004" an exhaust:.004-.006") Be sure to check the valves on a cool engine only.

If they are in spec, and you've got fresh oil in it, and the noise continues-next is the cam chain. You can check this by removing the valve cover from the top of the engine. You have an automatic adjuster on this bike, so there should be no slack in the cam chain. Specifically, check for slack on the rear side. If there is slack, you'll need to get your cam chain replaced.

If you've verified all the above, next thing to suspect is piston noise- usually from wear on the piston skirt. This can be verified by having a leakdown test done on the engine, since an engine with piston noise will also show alot of leaking past the rings. I hope this helps you out.

BALANCE SHAFT LOOSE?? CAM CHAIN TENSIONER FAULTY?

I don't know that exact model but all cam chain tensioners are automatic these days & have been for over 20 years

Hope this helps (if so please mark as helpful !!)

dont replace parts just because u get one opinion-mechanics r like doctors. I think ur timing chain is out of ajust or is worn-hows the oil level-purchase a repair manual or a pair of hiking shoes

does it sound like a chain rattle if so could be either cam chain tensioner needs replacing or even the cam chain itself is the noise bad because all chain driven cam engines make some noise
