Dirt Bike Chain Maintenance & Adjustment

[@badgumby9544]

Chain lube is a dirt and dust magnet. No matter how long you let it set after application.

[@Hanibul_Lecktor]

Chain wax, 100% never used properly. Bike on stand, in neutral. Spin tire, use heat gun on medium heat. Slowly heat chain to 140f or hot to the touch. Apply chain wax or lube while spinning the tire, 2-3 rotations. Let stand for 1 min, then take a rag to wrap around the chain while spinning the tire. 2-3 full rotations. Let sit 15+ mins before riding. Done !!! You now lubed the inside of the chain, removing the excess that collects dirt.

You should do a video over the best brands of dirtbike chains

My sprocket is the shape of a cd on both sides

[@AdrianOdobescuod16]

nice!! so put some magnets on sprocket and some magnets on chain and ride safe!! :D

[@borntwice4724]

You’re good.

[@hamburgerklay7679]

Its probably good

[@djp3819]

Are you still running it today?

[@gynn4622]

by the time you spend the money on a chain brush and specific chain lube you might as well buy another chain. Because you go through the chain lube let me tell you. just use some waste oil or 3in1 oil or really anything

[@bellyacre1]

I just use 90 weight gear oil. I always have extra in my garage. And it's not used very often. Also, I replace chain before it can deform sprockets. Chain itself not so expensive.

[@gray_wolverine63]

Great video 👍🏼 I also need your help on how many ft-lb did you do on your front sprocket someone else said 52 what did you do yours at ? I own a 2020 KLX300R. Hope you can help. Thanks

[@amryamaha]

I don't recommend spraying chain lube towards the direction of the brake rotor....

[@rmatvmc]

That's a good point to make. Some chain lubes can overspray. Thanks for sharing

[@vsrziege4872]

Also i would spray in the bottom not the top of the chain

[@Josh_Wright992]

I never use chain lube it's sticky and it'll wear your chain and sproket, just think the chain lube is sticky right, so what's the dirt doing when it catches that sticky lube on the chain, it's like putting sand paper to your sprockets and chains, I only use WD-40 after every wash and every time I go for my motos and it leaves the chain clean

[@johnnyaltomare2422]

josh wright WD-40 is a degreaser, so it takes any type of grease or lube. Chains have lots of moving parts and they move fast so they need some type of lube. And about the sticky part-anything wet will allow dirt to stick to it easily, so you just have to let it set in and clean your chain frequently.

[@Otravistafoto]

HI. Could you advise? I have got a new chain fro my Derby Cross City 125 moto. At the begining i was hard to even put it on as it was so tight. Right now after 2000 km and 6 adjustments every 10days The wheel is already 2cm to the back. Could chain stretch so much? Would the Chain tenser solve the problem? Thanks for any advise

[@JohnsonsNonsense]

great videos! keep them coming

[@rmatvmc]

johno258 We are glad that you like them! Thanks for letting us know!

[@Soloman1]

After changing new roller, my chain started producing sound! Is that the problem of dry roller??

[@rmatvmc]

No, if you're roller was pretty worn out, it's normal to have some noise. Especially if you put an aftermarket roller on with a harder compound.

[@SketchyKirby]

Which chain is the one used in the video?

[@azrida9543]

I got all brand new, but the bottom of my chain seems like it's rubbing the chain guide. I'm thinking shaving the inside of the chain guide what r your thoughts?

[@greaselover3248]

Awsome awsome awsome video helped me out so much thank u so much

[@tomsprusis7560]

What's the golden part called that is between the front sprocket and the engine?

[@rmatvmc]

That is a case saver 👍🏼 - Wes

[@jackadams3185]

To Measure the chain just put 3 fingers behind the chain slider.

[@cyclesdraw5341]

When you get the chain 3 finger tight where you want it and when you sit on it and chain is really tight, is that normal or no??? Thanks!

[@masonhill4065]

Did you ever find out the answer? I'm curious too

[@Johns367]

Can you add a few links?

[@Jacob-wr7ch]

When you're cleaning and lubing the chain, couldn't you just turn the bike on and put it in first while it's on a stand so that the chain will spin for you? That's what I do. I clean it and lube it while the chain is moving.

[@rmatvmc]

That would be a safety hazard, sorry. We would not recommend doing that. Spinning the rear wheel by hand, works fine. Thanks for sharing your method Jacob! Vinny

[@Jacob-wr7ch]

Rocky Mountain ATV MC I was wondering why you said it was a safety hazard but then I thought about it, and it's common sense. If the bike tips back, there goes the bike! Sometimes when I go to clean it, I get scared that my hand is gonna get caught in the sprocket and get pulled down in between it and the swingarm. I don't want to lose a hand.

[@atc2239]

is there a way to repair rear swings career where the chain adjustment goes in because mine is broken and cant really adjust my chains. also sorry for bad english so i hope you understand what im trying to say

[@rmatvmc]

***** It depends on what is actually broken. They make adjuster bolt repair kits for certain bikes and that may be the best option for you. What bike are you working on?

[@LGR_LGR_LGR]

I found spraying the chain with wd-40 first then pressure wash the chain once dry lube the chain 🏍👍

[@bradleythomsen3083]

Doesn't wd-40 dry out the o-rings?

[@SachaBernasconi]

@@bradleythomsen3083 no, has been tested and prooved multiple times, it doesn't

[@drongojonkins8945]

None of these tutorials mention whether the rear suspension is slack, loaded or neutral when making the adjusments. Whether the bike is on a stand or weighted can mean the difference between five fingers and full tight.

[@GametimeSlime]

If the bike is on a stand when you are adjusting it, it will read incorrectly. Use a wash cloth stick it inbetween the chain and back sprocket rotate it a little towards the back and than make your adjustments that will give you the tru slack measurements as if the bike was already dropped

[@connor3288]

Yeah thats the problem with these videos and even service manuals. Best way imo is to put on centerstand or workstand, disconnect shocks/shock, and align sprockets and pivot point inline. That is the tightest the chain will ever be, set a small amount of slack there. Then reassemble everything and make a reference chain slack measurement you can use easily/quickly to know chain is loose enough. As long as you use the reference measurement in same way everytime, like always on sidestand, or center stand, so you can keep the swingarm angle the same, should be good. Better too loose than too tight.

[@gkling33]

​@@connor3288ain't nobody disconnecting the rear shock when adjusting their chain

[@oBlackCoffee]

I went to check my roller and it was totally missing, must have fell off on the trail somewhere.

[@rmatvmc]

I know a place where you can pick one up! :) www.rockymountainatvmc.com/p/3186/9522/Primary-Drive-Chain-Roller

[@borntwice4724]

Is olive oil ok to lube my chain?

[@rmatvmc]

I would not recommend that. I have heard of people using it on bicycle chains when they are in a pinch but motorcycle chain lubes are usually a lot thicker and able to withstand higher speeds without flying all over the place.

[@borntwice4724]

Rocky Mountain ATV MC I’ve got a 2019 yz450f, I had the sag set for my weight but I feel the factory settings for the forks are a little soft for my liking, what should I do to stiffen or firm it up a little bit, much thanks.

[@kalamite.enduro8426]

Yep , if you are Gordon Ramsay

[@WILLY52368]

It would help to someone make a video of snail type adjusters for a change

[@bobbystafford8753]

Can you raise the handlebars?

[@rmatvmc]

Depending on your bike you will most likely need some sort of handlebar risers. You can click the link below and enter your machines year, make, and model to see the risers that will work for it. www.rockymountainatvmc.com/parts/dirt-bike-handlebar-risers

[@MMin3r]

Can you guys do a video on how to remove the timing chain on a dirt bike? Possibly something similar to a 2003 yz450f?

[@rmatvmc]

MMin3r Are you just replacing your timing chain or what are you wanting to do? If you follow this link Motorcycle Top End Rebuild For Yamaha Four Stroke (Part 1 of 2) it will take you to Part 1 of our Top End Rebuild on a Yamaha which will be very similar to your bike. This shows how to properly dis-assemble the top end of a bike and once you get that far you are basically ready to remove the cam chain as well. As that's left is pulling the flywheel and then carefully dropping the cam chain down into the crankcase and around the sprocket on the crankshaft. You can also refer to your bike's service manual for instructions.

[@MMin3r]

I'm getting ready to do a top end rebuild on my bike. New gaskets, rings, and a timing chain, because I can hear it a tad bit when it idles. I have a service manual, but it looks so complicated in the manual, so I try to find better examples on KZbin. I've seen the Rocky Mountain ATV MC top end rebuild on that yami 4 stroke so many times. I really love how it makes a top end rebuild look so much easier than in the manual.

[@rmatvmc]

MMin3r Ha I know what you mean! They are saying the same thing, they just have to make it more complicated for some reason which doesn't make any sense. Yeah, definitely if you are already into the top end it's always a good idea to put a fresh chain in at the same time. I would refer to that Top End video as much as you can and then also follow along with the manual and it shouldn't be too complicated. If you run into any questions just let us know!

[@bornepic1626]

What happens if u dont change it??

[@Rcoombes40]

What’s the black padding that’s in between the frame and the chain that’s what I’m trying to look up and I don’t know the name can somebody help me.

[@rmatvmc]

I believe you are looking at the chain slider there! The part that goes around the front of the swing arm to help protect it from the chain.

[@P00P_]

[@cameronscott576]

Can someone please help me, on how to tighten my apollo 125 dB-18 chain!!

[@mxjoe1777]

When can you realy know that the time is to change chain ?

[@rmatvmc]

Look for signs of chain ware. Lot's of side play, flats spots on top and bottom, rust, or the method of trying to pull the chain away from the center of the rear sprocket. If you chain is worn and needs to be replaced, typically you'll have a small gap that appears when you pull on the chain. If the chain is in good shape, it will be nice and snug and not pull away from the sprocket. And as always, see what your service manual recommends.

[@boost219]

When it snaps lol

[@charlotteharliboyd1189]

Open end should face backwards away from drive direction

[@OGTylerP]

refer to manual... gotcha.

[@MrOmgSkittlez]

My manual says the chain for stock is 520x112 and my new chain is 520x120 so do I cut my chain to 112 links?, and what do I do with my chain adjusters it's almost all the way back? Please help

[@rmatvmc]

MrOmgSkittlez Yes. You will need to cut it down by grinding off the two pin links where needed. Before you cut down your chain, make sure you have the stock sprockets on the bike as well. Once you have the correct length cut, you can adjust your chain adjusters in and out for proper tension. Refer to your service manual for proper torquing. Check out our other related video at "2:16".

[@nflgreatestmoments8875]

@MrOmgSkittlez dont cut it just adjust it

[@rmatvmc]

gaming like a pro awesome pro Thanks for the comment! But in his situation he would need to cut the chain down due to the limited adjustability in the chain adjusters. An 8 link difference is a lot to compensate for. Cutting it down would be his only option or to simply return the 120 link chain and get the correct length. Thanks for watching!
