Bike is a 1996 ZX6R. Cam chain is very noisy. Removed tensioner and it seems to work fine. I saw manual adjusters on ebay. Is there more adjustment in a manual one? Could I get the seaon out of it with a manual adjuster?
If your chain is makeing nois it would be a good idear to replace the chain a manual cam chain tenshioner will take the slack up but what about the valve timeing a worn chain will throw it out due to the chain stretching plus the manual tenshioner will make the guides wear faster if ya auto matic tenshioner has reached its limit that means replace chain no ifs or buts

Hi, Mcninjamick the vast majority of service, parts, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee around $10 sometimes more and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, then there is eBay where you may be able to find what you need at a very high price because of its age and rarity. Most of the "FREE" manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have.

Put the motor at Top Dead Center "TDC" on the compression stroke of the number 1 cylinder. Then loosen and tighten the cam chain adjuster bolt on the back of the cylinder. If you are dealing with an automatic cam chain tensioner that has gone bad. Unbolt it from the back of the cylinder and replace it. Or if it is internal, take off the valve cover, unbolt the tensioner from the back of the cylinder, slide it out the top of the head, slide in the new one, set the motor to TDC , and set the tension on the new tensioner.
Here is a picture of what your cam chain should look like. Note the carb is in the upper right of the photo (so this is the left side of your motor facing backwards towards the carb)
This particular photo is from a CRF250F but the diagrams I saw look almost identical. It will be obvious that there will be some tension vs. losing tension when you screw in or out the adjuster. Just make sure that you aren't over-tightening it. Just take up some of the slack if its noisy.
Well I guess the type and model of motorcycle would help.
However, most camchain tensioners are basically automatic. They bear against a long, curved nylon dampener that rides the slack (trailing) side of the chain. This pressure is made by a spring inside the chain tensioner housing itself and is not a serviceable part.
If housing is bolted up tight, all available tension is employed. If chain is still slack...camchain is worn out must be replaced.
Camshaft and rocker arm gaps maybe providing all the noise also, maybe time for a top end service, whatever the bike!!
hi,if it is anything like the 400r,the tensioner will be automatic and non adjustable,normally the chain guides wear out before the adjuster reaches it outer limit,they are quite esay to replace but you need to take the cams out to do it,you will probably find that a lot of the noise coming from the motor is the clutch basket,as a matter of course they are quite noisy once you start to get a few km on the bike...cheers
YOUR MECHANIC IS SOMEWHAT RIGHT TO AN EXTENT. KAWA 1500'S ARE CHARACTERISTICALLY NOISY IN THE VALVETRAIN! BEEN AROUND THEM SINCE THEY WERE BORN. NOW IF YOURS IS PARTICULARLY NOISY, HAVE THE MECHANIC CHECK THE VALVETRAIN AND CAM CHAIN TENSIONERS FOR PROPER ADJUSTMENTS. THIS IS CRITICAL FOR THE LIFE OF THE ENGINE!
Cam chains are self adjusting. They have a tensioner that takes up slack as the guides wear and the chain stretches. You may be able to get away with new guides if your chain isn't too stretched. Look for pieces of plastic in the oil, which will signal work guides. It is possible you are hearing the valves rattle, and it would be time for a valve adjustment.
