How To Check and Adjust Your Motorcycle Chain | MC Garage

Checking and adjusting chain tension is a fundamental bit of maintenance, right up there with checking your oil and tire pressures. Very basic, pretty easy, and also really important! Run your chain too loose and it’ll slap around and may jump off the sprocket and throw you on your head. Run it too tight and you’ll wear out your chain and sprockets and inhibit rear suspension action. In this video from the MC Garage, Ari shows you how to check and adjust that chain for optimal performance and longevity.

Motorcycle chain slack is a fundamental piece of maintenance, right up there with checking your oil and tire pressures. Very basic, pretty easy, and also really important.
Why does chain slack matter? Well, if your chain gets too loose, it could jump off the sprocket, jam up, and chuck you on the ground. A loose chain is also going to slap around and make a bunch of noise and create a lot of driveline lash.
A too-tight chain, while less common, is also bad. If your chain is too tight it’s going to wear out the sprockets and chain faster, plus it can inhibit suspension action.
How much chain slack you need varies based on the bike, so check your owner’s manual or the sticker on your swingarm for the spec. For streetbikes, the figure is usually between 30 and 40mm. Your owner’s manual will also tell you whether to measure the slack with the bike on the sidestand, or with it held vertical on a rearstand.
Armed with a slack figure, it’s time to take a measurement. Using a ruler or tape measure placed against the underside of the swingarm midway between the sprockets, pull the chain down and note the measurement, and then push it up and check the number. Now calculate the total deflection by subtracting the smaller number from the larger number.
If your chain needs to be adjusted, the first thing you need to do is crack the axle nut loose. Don’t spin it off, just loosen it enough to allow the wheel to move in the swingarm. There are several different styles of axle adjusters out there, but most will have a lock nut that you need to crack free. Then turn the adjuster ¼ turn at a time to shift the axle position and change the chain slack. Make sure you’re moving the left and right side the same amount, and check the reference marks on the adjuster to verify that the wheel is straight in the swingarm.
Once you’ve made an adjustment, recheck the tension. It might take some trial and error.
Once you think you’ve got the slack set, stick a rag or a screwdriver under the chain and rotate the wheel to pull the axle forward against the adjusters, then tighten down your rear-axle nut to the proper torque. Then pull the rag out and tighten the locknuts on the adjusters. Finally, recheck the slack one more time. With that done, you might as well wipe your chain down with some cleaner and give it a shot of lube.
And that’s it! One of the most basic maintenance procedures there is, so you don’t have any excuse not to do it! I hope you enjoyed this vid. If you have questions or video topics, leave ‘em in the comments section. Until next time, ride safe.

For new riders attempting this, listen to what the advice he is suggesting as a 1/4 turn at a time with the adjuster nuts. A full turn or two moves the wheel a significant margin and you will know right away in the chain tension or looseness. Do one quarter turn each side. Check chain tension. Check twice. Adjust as necessary. Check chain tension. Check it twice. Adjust as necessary. The only thing I wish was the notch marks on the bike were large lines with 3 smaller lines in between the large ones for finer adjustment.

So you loosen both adjusters on both sides in a progressive way to bring the wheel back in an equal amount? So 1/4 - 1/4 each side then check 1/4 - 1/4 correct? snug the locking nut then check wheel alignment?

@@izzy8609After loosening the rear axle nut, I loosen both side locking nuts and then one side at a time, I turn about 1/4. Then I turn the other side 1/4. Then I check my chain slack. I check the chain slack like 2 or 3 times to ensure I am confident with my observation. If I need to tighten more, I do 1/4 turn on the adjuster bolts, one side, then the other. Then I check my chain slack again. Once I am satisfied with my chain slack, I use a flexible (fiberglass?) tape measure with Millimeter markings to ensure my knotch marks and alignment lines are within 1mm. My bike has markings that are 5mm apart. This matches the tape measure perfectly. I line up my tape measure to the bike markings and then check the opposite side. If my alignment line is in the middle of two alignment knotches, that would be on the 3mm line of the tape measure. I ensure the opposite side is also on the 3mm tape measure line. Not the most efficient method, but it is very accurate. I also use a Milwaukee fat tape measure to measure my chain slack. I set on level surface, raise the tape measure. Identify my lowest point and highest point but the tape measure never moves. The tool in the video looks even more accurate. When done, ensure you are using two wrenches to tighen the adjuster nuts. You don't want to use one and then turn the adjuster nut a tad more. You must hold it in place while tightening the lock nut. After all that, make sure you torque the axle nut properly. Mine is 95.9ft lbs. I set for 95 ft lbs and use the last .9 to rotate the nut to where I drop the cottle pin in. The manual says 95.9, and then up to a 1/4 turn more for the cottle pin. I just don't want to over-tighten it.
Brilliant video just saved me £50 and now my gear changes are so much better. Videos like this make me want to do more work on my own bike
Been at this for literally my entire life, as in, I started riding at 9 years old and am 54 now, never not having a bike in that time. I have still never heard the rag in the sprocket trick. Thanks for that one!

Good vid, one of the most important bike maintenance that many riders over-look. Liked the 69 tribute on the side, RIP Nicky Hayden.
would like to add that its always a good idea to adjust the tension in the tightest part of the chain, otherwise you risk over-tightening... great video as always

As with most maintenance jobs, the manual will tell you not only what the slack should be, but exactly where on the chain to measure this slack. You can see it if you pause at 1:19, the manual shows you precisely what to do.
1:22 this is correct but it’s important to spin the wheel and measure the slack when the chain is at its tightest point during the rotation meaning find the tightest point and then take your measurement per most manuals

Another very informative vid! Good job guys! I like the trick with the rag. Need to try that next time. I think a good topic to cover would be suspension. I feel that suspension adjustments are a very underrated necessity to getting the optimal performance / handling setting out of your bike.
I'm looking forward to the video showing the alternate methods for aligning your rear wheel straight to the bike. Love the vids, Cheers!

Thanks. Your video clarified a few steps that were not explained well in either my BMW manual OR the Haynes manual.
The best video out there -straight to the point. After several videos i'm convinced. You got a subscriber buddy.
I wanted to say thank you for the video. I had to keep readjusting and readjusting. Once you have the chain tightened the right side will move when you are tightening the axel nut, keep the wheel pressed where you need it to be as you tighten or it will move and throw off your measurements. Took me three times doing this to figure this out. But taking the measurement was the best method.
Thanks Ari, your videos are simply excellent.
Clean and lube chain first. Take a short ride. Chain will slack even more after lubing. Then adjust. I found this out when I adjusted first then lubed,. chain got loose, went back and had to re-adjust.

I am coming from a video from 'Fab Motorbikes' and he said the upper section of the chain should not be moving while you are raising/lowering the lower section. With Ari's measurement on 1:35 it was moving. Bike manual doesn't say anything also. I am lost on this one.
@Mech.E
Жыл бұрын
@ fab motorbikes is most likely right. Otherwise you are taking or adding slack from the upper side as the tension changes. It's also in line with what the picture in the manual/swingarm shows so I assume that's the way.
@jridenour31

@@Mech.EYou don't need slack on the upper side. All of the slack is going to be on one side when you're riding. If you leave slack up top, your slack measurement is going to be tighter than the actual number.
