On the older Sportsters you check the chain for freeplay on bottom.shuold be 1in - 1 1/2 in freeplay.Check in a couple dif spots.
to tighten loosen axle nut,loosen jam nut ,turn bolt in until correct freeplay is there turning each side the exact same amount.Retighten and measure from axle to a set point on each side to insure wheel is lined up close.Remember this isnt rockett science you dont have to be percice just close.Check freeplay at least once a week and every ride for awhile after a new chain is put on.
BTW I ride a old Harley too

Every 600 miles or 1000 km. Your motorcycle’s Owner’s Manual will have directions. With most motorcycles, you check the tension with the bike on its side stand. I found that with my Honda CB-1 up on a shop stand, I could get the tension right. The key is to have the suspension at the correct sag. You need to check the tension at several points along the chain’s travel around the engine and wheel sprockets. The tension should be set so that the loosest spot and the tightest spot are still within the slack tolerance specified in the owner’s manual. If the tightest spot is at the tightest allowed and the loosest is beyond the tolerance, then it’s time to get a new chain and sprocket set.

95 gpz chain tighten how to


hey Dominico,
This is the way PROFESSIONAL mechanics do a chain/sprocket check and drive chain alignment and tension.. Proper chain tension is very important to the life of your chain and sprockets and performance of your bike. First, you need to check to see if the chain/sprockets need replacing. (Chain and sprockets are ALWAYS replaced as a set (-all-3)..if you replace a chain on worn sprockets.. the chain will stretch out QUICK.. and if you put new sprockets with a worn chain.. the sprockets will be worn out QUICK too!!) ...To do this..the bike needs to be on the center stand or bike stand...NOT on the side stand...
...now...--remove the chain guard-- next..Sprocket check time - take one hand and squeeze the chain (grab the chain above and below the swingarm) at the point between the axle and the swingarm bolt.. as hard as possible. to take all the slack out of the chain and put the tension completely around the back sprocket.. while you are squeezing the chain as hard and tight as possible.. - with your other hand - try to lift/pull the chain off the rear sprocket.. IF you can pull the chain off enough to see if there is a .200" or 5mm max. gap between the chain and sprocket - under the chain... or MORE THAN A HALF a tooth groove under the chain..or the chain pulls up more than two teeth...OR the teeth on either sprocket are "pointed thin" or rounded inside....you need to replace the chain/sprockets.
...ONCE you are sure the chain/sprockets are good..its time to CORRECTLY align and adjust the chain tension. Loosen the axle nut.. DO NOT remove it.. now - tap it gently to make sure its loose...loose the chain adjuster nuts.. back them off a good bit, but do not remove them...you may,also need to loose the rear brake caliper mounts ..you should be able to move the rear wheel forward and backward with your hand.(this is to assure you have sufficient "looseness" to make the proper adjustment...NOW - pull the rear tire backwards until it stops.. - run the adjuster nut(s) until they are just snug..ALIGNMENT - This is CRITICAL - (did you remove the chain guard yet?) - do that now. You must be able to see down the entire length of the chain (above the swingarm)..The chain MUST RUN IN A STRAIGHT LINE!! .. The little marks on the swingarm are just "guides".. never use them as perfect.. the only way to assure CORRECT ALIGNMENT is a visual check of the chain to make sure its in a straight line!!!! - ...ANY bend, crook, or mis-alignment will cause premature wear and tear, and make it harder for your engine to make it turn. - Now - Rotate the wheel and find the tightest point of the chain... there is one, and its normal... LEAVE the tight point located between the two sprockets on the top of the swingarm. This is where you will "feel" for the correct tension.
The biggest thing most people miss when adjusting the tension is having the AXEL/NUT and the SWINGARM PIVOT SHAFT and the COUNTERSHAFT C/L (front sprocket shaft) IN A STRAIGHT LINE - ALL THREE ARE ON THE SAME PLANE!!!!!
. NOW, You may have to get a buddy to help pull the swing arm up.. (I use a tie down strap through the rear wheel and over the seat pulled tight enough to make AND KEEP the STRAIGHT LINE!!)
..Once you have established the straight line - --- - --- - and MADE SURE the chain is RUNNING STRAIGHT on both sprockets.. NOW _ its time to adjust the tension. There WILL be a tightest and loosest point of the chain..(normal).. you MUST adjust the tension using the TIGHTEST point of the chain....set the tension so you can move the chain up and down (total movement) about 1 3/8 inch to a max of 2 inches!! Once you have established the chain is straight and the tension is correct, its time to TIGHTEN EVERYTHING in order... start with snugging the axle nut.. then snug the adjuster nuts more..-- DOUBLE CHECK you chain alignment.. now - tighten the axle - TIGHT!!... tighten the adjuster nuts..lock down the lock nuts.. tighten the caliper.. TRIPLE CHECK the alignment... double check the tension...double check all the nuts... install the chain guard... REMOVE whatever you use the keep the straight line straight..

TRIPLE CHECK ALL NUTS!!! NOW ROTATE THE REAR WHEEL AND CHECK FOR BINDING AND MAKE SURE THE CHAIN IS WORKING CORRECTLY AND NOT TOO LOOSE..
KNOW you have done a job correctly!! (I am a factory trained mechanic, race engine builder, port work guy, race tuner.)..
GREAT JOB!!

StarTrac NXT Chain Tensioning & Alignment Video


About This Video


Adjusting Chain Tension and Alignment on a StarTrac NXT


  • In this video, we show how to tension and align the chain and flywheel on a StarTrac NXT bike


  • First you see an example of a chain that is way too loose


  • To correct this loosen the flywheel bolt on both sides of the flywheel


  • Loosen the tension nut on the sprocket side of the bike and tighten the tension bolt until you get the proper deflection on the chain



    • A properly tensioned chain will have roughly 3/16" of deflection




  • Tighten the tension nut and the flywheel nut on both sides as shown in the video


Check the Alignment of the Chain and Sprockets after Making a Chain Tension Adjustment


  • Misaligned chains will look like they are walking from side to side where they enter and leave the sprockets



    • This can cause noise, premature wear, as well as making the chain look to be jumping from side to side during use




  • To correct this, loosen the flywheel nut on both sides of the flywheel, then loosen the tension nut and adjust the tension bolt to move the flywheel in the proper direction needed to align the chain with the flywheel sprocket, as seen in the video



    • Note: If you have already achieved proper tension of the chain, adjusting the tension nut on the opposite side from the sprocket will help to keep the same tension on the chain




  • Don't forget to check the chain tension after making an alignment adjustment

I can't tighten the chain on my stihl ms 251 chain saw


Pull the side cover and check for a broken or misaligned chain tensioner. I assume that you have loosened the bar nut on the side cover before attempting to adjust the chain tension. The methiod varies depending on whether your model has the side chain tensioner or the quick chain tensioner.

Need to put a new chain on a Husqvara 235 14 inch chain saw?


Check that the chain brake is in disengaged position by
moving the front hand guard towards the front handle.
Remove the bar nuts and remove the clutch cover (chain
brake). Take off the transportation ring.
Fit the bar over the bar bolts. Place the bar in its rearmost
position. Place the chain over the drive sprocket locate it in
the groove on the bar. Begin on the top edge of the bar.

Make sure that the edges of the cutting links are facing
forward on the top edge of the bar.
Fit the clutch cover (chain brake) and locate the chain
adjuster pin in the cut-out in the bar. Check that the drive
links of the chain fit correctly on the drive sprocket and that
the chain is in the groove on the bar. Tighten the bar nuts
finger-tight.
Tension the chain by turning the chain tensioning screw
clockwise using the combination spanner. The chain
should be tensioned until it does not sag from the
underside of the bar.
The chain is correctly tensioned when it does not sag from
the underside of the bar, but can still be turned easily by
hand. Hold up the bar tip and tighten the bar nuts with the
combination spanner.
When fitting a new chain, the chain tension has to be
checked frequently until the chain is run-in. Check the
chain tension regularly. A correctly tensioned chain
ensures good cutting performance and long life.

I hear a clunking fron the front chain sprocket . I think the chain needs adjusted on my 1995 kawaski zx1100.


Get the rear wheel off the ground and adjust the chain tension. When checking the tension spin the rear wheel and check that the tension does not go slack or get tighter. If the chain is riding up and down the sprocket teeth then the chain is stretched and needs to be replaced. This is the grinding/clunking noise you are hearing. If the sprockets are worn consider a chain and sprocket set, it can be a less expensive option than buying the parts separately.

Tighten chain?


Depending on the model, you adjust the chain tension using the screw that is located either between or below the two nuts that hold the sprocket/bar/chain cover. Loosen the nuts and turn the screw clockwise to tighten, counter-clockwise to loosen. Once you have the tension set, lift up on the bar from underneath and tighten the two nuts. Proper tension should show about half of the chain drive, and should only be done when cold. After 4 to 5 minutes of run time, stop the saw and check the tension again. A little heat in the bar/chain will cause it to loosen up. It will need re-adjusting.

My first chainsaw...am seeking general advice on product use etc


Ok to get correct tension on chain, basically loosen it a little until the chain on the underside of the bar is hanging a little... Now start tightening it up again. Basically you want the chain (the main part of each link) to be just touching the the underside of the bar. This will give correct tension... Note that chain does expand as it heats up so it may loose tension... so this is perhaps best done when the saw and chain has warmed a little. Also, new chain will stretch a little naturally so check tension each tme you use the saw.

If you do not know hoe to sharpen a chain properly, it is best to get someone else to sharpen it, or buy a new chain... Eventually all chains will need to be replaced because they can only be sharpened so many times before the cutting teeth become too small to work effectively or safely.

As for oil, if it is an electric chain saw, you only need chain/bar oil. Any good name branded bar/chain oil designed for chainsaws will work well.

Chain's tension


Every 600 miles or 1000 km. Your motorcycle’s Owner’s Manual will have directions. You need to check the tension at several points along the chain’s travel around the engine and wheel sprockets. The tension should be set so that the loosest spot and the tightest spot are still within the slack tolerance specified in the owner’s manual. If the tightest spot is at the tightest allowed and the loosest is beyond the tolerance then it’s time to get a new chain and sprocket set. ,
