How To Adjust a Motorcycle Chain and Sprockets at RevZilla.com

[@Eunostos]

You made this simple enough that I managed to do this maintenance task for the first time... despite Autism. So, thanks. I will be checking your other material.

[@ZTRCTGuy]

Ben Richards... Really? Having autism doesn't impede doing maintenance work on your motorcycle at all... On the contrary, the eye for details and perfectionism (just a few examples) makes you more likely to do a better job. I've got Aspergers myself.

[@Sfekke]

@@ZTRCTGuy 8 months late but, while Autistic people have an eye for detail, some have trouble following steps if they aren't clearly laid out. It depends from person to person, I for one don't but I know someone who cannot get most things done without step by step instructions.

[@davidverba3431]

@@ZTRCTGuy you have no idea how bad his autism is so you should let him be happy and proud of himself without downgrading the fact that he did it and you have aspergers. maybe hes new to bikes and is really happy with himself and just wanted to share it. leave him alone.

[@ZTRCTGuy]

@@davidverba3431 I'm not downgrading anything. Simply pointing out that it makes no sense in the light of autism that one would have trouble adjusting motorcycle chains, especially considering it's symptoms. This video is a clear step by step instruction. I do not understand how you can think I'm purposefully downgrading someone with autism, because I aren't. Also, I could use the same argument you did. You also don't know how bad my autism is.

[@xaviermccloud4586]

@@ZTRCTGuy I agree with you. People who like to point out their disabilities in situations that don't require it are usually trying to gain acceptance and attention like all humans ;). We all need attention sometimes bro.

[@randybone3148]

Most (all?) states have a deal where you can get your motorcycle learner's permit, then take an accredited motorcycle training course (if you can ride a bicycle, you can handle the little 250 cc bikes they use in the courses). If you pass, and pretty much everybody does who makes an honest effort, then you get your motorcycle license for a very small investment. I know people who never got around to buying a motorcycle, but are still very proud of the fact they earned the license.

[@slimshadyowns]

im not sure how that is a deal...that sounds like getting your license...i live in communist canada and it is not any harder to get than that. just like getting a car license but with a bike instead...as the name would imply...

[@RedxFaction]

By "Communist Canada" you must mean "a nice place to live called Canada, which I have minor gripes with that I blow out of proportion" because you just seem kind of that guy. Anyway, you can get your license in the US just by showing up with a bike and taking the road test. The motorcycle course coupled with the road test is to actually teach you how to ride properly. It also lowers your insurance premium because it doubles as a defensive driving course. Motorcycle riding is inherently dangerous, and proper training can save your life. That's why it's a deal.

IS a half inch to tight on your chain?

[@willturner397]

Yes but Lemmy's balls need to drop. That high pitch, cracking voice requires face crush.

[@DillonMartin]

First time adjusting my 2002 Yamaha FZ1 chain. My bike rode noticeably better afterwards. I was a 1/2 inch over the max slack measurement per my manual. This was a great demo! As the man said, look at your manual and apply the knowledge in this video. Personally, I ended up measuring off the bottom of the swing arm instead of the top. This is the only thing that was not verbally expressed in this video, but (based upon other videos) should be totally fine to measure that way. LOVE this channel!

[@NubsWithGuns]

Put the ruler and manual away and learn what your bike wants instead. My manual tells me to make my chain so tight that it will mushroom rollers in a week.

Lemmy good instruction. I'm an instructor for safety and you do a fantastic job, both with your voice and knowledge.

[@sammyscrap]

I just got one of those ChainMonkey tools and have only used it once so far, but I really like it in terms of eliminating the whole guess and check approach to achieving proper tension. Chain tension is one of the most frequent maintenance items to perform so it makes sense to invest in tools that make it a breeze.

[@zeez9053]

Cannot begin to think off a better how to video instruction

[@broderp]

Hey Lemmy, it's not so simple if you dont have the nice lift and are having crouch down and do this. Also "floating" the ruler is a bad idea. You can be off by a considerable amount leaving the chain out of speck. I use the back side of a tape measure, or paint stir stick. Using your bike as an example, rest the stick or tape measure on the swing arm. I mark the low point of the chain on the stick then mark the high point. I now have two marks that I can accurately measure. Because the stick was resting on the swing arm, its repeatable with no floating ruler to mess with. Many manuals stay to measure the chain slack while on the kick stand. Isnt this the same as being on a paddock stand? The point is to have the suspension compressed. How much difference is there in chain slack between a motorcycle on a kick stand vs a paddock stand? I will tell you there is s ton of difference in the labor required to recheck and readjust! Awesome video Lemmy, as always.👍

[@idnic19]

[@172389]

Even though this is a "one bearder", for someone who isn't good with tools or with mechanics in general it looks like it would be really easy to F this up. Video was very helpful so I know what I'm getting into before I take everything apart and realize I'm in over my head.

[@Bass1923]

Terrific maintenance videos, Lemmy. One suggestion for this one. Go ahead and let your ruler rest on the top of the swing arm because this is the only way to hold it steady when measuring the slack. You can't hold it steady in mid air while raising the chain. The starting point for the pin will now be at say, 3/4 inch. Lift the chain and see the upper limit of the pin, say it tops out at 2 1/8 inches. Subtract those two and you have 1 3/8 inches with the added benefit that this is accurate because you can be sure the ruler didn't move during the process. I will watch your other vids because they are always informative and give me confidence to do my own maintenance. Thank you.

This dude's the real deal and not just pulling our chain. Sorry, that just came out. No pun intended :) lol

[@memine5723]

The KLR comes with the tools you need, less a measuring stick. So if you bike comes with a tool kit you can check it to see if it comes with the correct sized wrenches.

[@patdennis3751]

The motion pro alignment tool is nice, but for those of us without all the fancy tools you can just eyeball it for square and spinning the wheel. Spin the wheel and the sprocket teeth should self center on the chain rollers if the wheel is squared up

[@showtime813]

Information in this video is priceless.

[@skidz8426]

btw when you measured the chain slack 5:45 you said it was 2 3/4" it was more like 2 1/4. you had the ruler on the swing arm so the bottom of the chain and you were measuring to the top of the chain I'd say the chain was about half an inch. you should either measure from bottom to bottom, or top to top of the chain.

[@drew657]

Out of spec is out of spec. Could've been 5" and the result is the same: needs adjustment.

[@DarxusC]

I'd love a video on what to do when, for some reason, the manual's specs aren't useful. For example, on my bike, when tightened to spec, the chain gets way too tight at its tightest point. So, maybe a suggestion of amount of slack at the tightest point (possibly with both sprockets and the swingarm pivot lined up, if you don't have any tensioners).

[@ldrider82]

I noticed you don't stuff a rag in the rear sprocket. I have seen other videos where they do or even use a screwdriver in the sprocket. Is this really necessary?

[@jelleschele4398]

I need to tighten mine as wel but if i put my axle way back my chain is still to loose but im concerned if i take 1 piece of it will be to short

[@themza912]

You should've mentioned the chain alignment check tool when you mentioned special tools.

[@phantomshtter]

Okay... what if you've changed rear sprocket size? Factory spec goes out the window. What then? Total deflection (bottom to top) isn't a listed spec for my crf300. Increasing diameter of the rear sprocket moves the chain further away from the swing arm. How much at the measurement point I don't know.

[@MrFameone206]

Thank you I knew I needed too adjust the on 2k R1 but didn't really have the confidence to do it... but watching this made me realize it's not that difficult to do... love your video bro thanks for all the great tips

[@jessiedivincenzo5215]

I wouldn't trust the stealership to do it. Recently had a blowout on a ride up in the canyons and had to get towed back to the stealership and I don't believe they got my rear wheel perfectly aligned it's off to the naked eye. Better to do it yourself rather than put your life in someone else's hands. There are good mechanics and then there are those that in no way should be working on bikes.

[@thealvaco]

watch out for uneven chain slack people. One part of the chain may be slightly longer than another. Find the tightest spot on you chain and work with that slack.

[@chrisc6874]

thealvaco yes, he should have mentioned that. it's often overlooked. also, the trick with the screw driver in between the sprocket and chain when tightening. I'm also wondering about the floating ruler as he's measuring. that's kind of inaccurate cause your hand is moving around. i didn't understand why he didn't just set the ruler against swing arm, push chain down and measure range of travel from where center of pin was. that way the ruler is held steady

[@thealvaco]

ZLA Lemmy thanks for the reply.

[@paulkazjack]

@ZLA Lemmy if your chain has tight spots its because there's ovality in the running gear.

[@172389]

Kawasaki Vulcan S owner here, just bought it and haven't had to adjust the chain slack yet. The owners manual says "set the bike up on it's side stand (bike does not have centre stand), rotate the rear wheel to find the position where the chain is the tightest, and measure the maximum chain slack by pulling up and pushing down on the chain midway between the sprockets" My question is, how do you rotate the rear wheel when the bike is on it's side stand? The wheel is under weight in that situation.

[@Hermelin.G1]

172389 ask a buddy to help you. he should lift the back slightly and then you spin the wheel.

[@alialnasri6972]

[@the_original_Bilb_Ono]

I have a cb250 and at 65mph on highway my bike is revved way too high. How do I know what adding/subtracting teeth will do to my RPM/speed combination? Do you MUST change both sprockets if you change the teeth to one of them? I just need a bit less RPM at 65mph. Can I use the same stock chain as well? I'm so confused what I need to lower my RPM at 65mph...

[@RevZilla]

The change in speed is a simple fraction or percentage, as the sprocket sizes are a ratio. Generally sprocket averages are around 3:1 or so, like 45 rear and 15 front give or take a few front or rear. If you know the RPM at 65mph with the stock sprockets, use the fraction of the new sprocket sizes to calculate the change in RPM. There are online calculators that will do it for you as well. As for changing sprockets, you don't have to change both. You can just change one if you want. The cheapest is generally to just go up a tooth for the front sprocket (the countershaft sprocket). That should drop the RPM at 65 enough to make a difference. However, understand that acceleration will be slower. -DrewZilla

[@punterash]

Nice instructions Lemmy! I need a quick consultation if you can help me. I am from India and own a Royal Enfield Thunderbird 350. My O-ring chain makes a clicking sound every time I accelerate from idle or very slow speeds or go over a fairly bad surface. I tried cleaning the chain, lubing it with both wet and dry lubes but it did not help. My spoked wheels are slightly bent from an ugly patch of road but otherwise everything is according to factory guidelines. What might be the problem from your experience? I do not hear the clicks during high speeds.

[@RevZilla]

It could be the chain slapping the swingarm during acceleration or when the suspension moves through its travel over that bad surface. -DrewZilla

[@nomadpi1]

Noticing comments - some applause. However, as a math teacher, I critique this as you skipped two points. (1) you didn't show, or tell the distances, the marks on the bar , along the guide forward/backward are in lengths. (2) Putting on the chain link guide, there was nothing said re: what to do after mounting it - how to read, or where to examine the data. Also, show an example or two of common error someone might encounter. Rock on!

[@quez.designs]

First find the tightest spot on you chain and work with that slack. It's often overlooked.

[@jonmulack4226]

If you have a tight spot, your chain is on its way out.

[@Fyrespit]

@@jonmulack4226 Tight spots are caused by eccentricity between the rear sprocket and axle, thus even new chains can have tight spots.

I need help finding the right chain size for my 2017 KTM 690 Duke. I was looking at the EK chain 525 ZVX3 which says it's compatible with my bike on your site but I don't know what size. Also a compatible rear sprocket to go with it.

[@johnscott9829]

Does it make a difference with it on the kick stand or like you have it on the center stand?

[@blob2092]

You should check your manual. Many bikes specify that the tension should be checked with the bike on the sidestand.

[@wbrownati]

Great video. Very professional sounding.

[@TheJazzhandz]

putting the ruler against the swing arm is probably what you should do instead of just floating the ruler. seems kind of like the way everyone tries to measure things by holding up their hands.

[@TheJazzhandz]

Yeah I get that it's pretty leanient and I see that you do have to remember about the production, I too work with cameras and production occasionally. But it's just odd that you wouldn't place the ruler against the swing arm and then just use whatever numbers the chain moves too. But hey it's arguing semantics so whatever. Keep up the good work tho

[@TheCodesterr]

When you measure the chain slack do you measure the start of the bottom end on the chain to bottom end when you pull it up or bottom end to top end? Or vise versa?

[@RevZilla]

It depends. The manufacturer generally specifies where and how to measure the chain slack in the owner's manual. -DrewZilla
