How to Change Your Chain & Sprocket on Yamaha R3

After 13K miles I noticed that my chain has been stretched to its limit and hear it slapping the rear swing arm so it was time for a replacement. Had my friend Vern help me out with the making of this video, and wanted to give him a Big thanks!. below is a link to what chain and sprocket I used for this install. You can also change the Gear Ratio to ADD or Decrease speed.

At 8:42, the purpose of the sprocket guard is to keep the chain from catching the studs should it ever come off the sprocket and instantly locking your rear wheel.

[@brosephjoseph9178]

It's like a chain catcher bro! If your chain broke it keeps it from jamming up on your sprocket bolts and locking up your rear tire.

[@ACProductions77]

thanks for solving the mystery of that part for me , for the longest time I didn't know what it was for, not even the dealership where I bought it at the time didn't know what it was for. So im wondering if that's the main purpose of it why doesn't all bikes have this!?

[@brosephjoseph9178]

AC Productions Yeah I'm not sure man! I left mine off and my old dirt bike didn't have the studs it had thous set bolts that sat flush with the sprocket. with proper maintenance it should be fine.. Ride safe man!...

@@ACProductions77 Seriously replace that rear sprocket guard man!

[@ACProductions77]

@@maxpressure1063 what do you mean? it has been removed when i had did this video and is long gone.

[@maxpressure1063]

@@ACProductions77 look. It's a safety device. It keeps your chain out of wheel if thrown.

[@330.Custom.Diecast]

Awesome video as usual 👍. I don't see the reason to break the chain off when your replacing the rear sprocket and removing the wheel anyways?

[@ACProductions77]

its because I was also replacing the chain as well.

[@330.Custom.Diecast]

@@ACProductions77 I really appreciate your videos, you cover pretty much all the bases on this bike. Your HID projector retrofit video helped me immensely; reviewed it many times with great results 👍.

[@coolwip32]

Yea I’m with David on this, that’s just adding a unneeded step.

[@mobiletech.dgmain3074]

It keeps the chain from getting caught in the bolts, if it ever slips off or brakes.

[@ACProductions77]

Thank you for the reply, I’m not sure why don’t all bikes have this safety feature

[@Admiralty86]

Remember, these guys know what they're doing. Don't just wander into this project on your own willy-nilly. Having a chain malfunction/disconnect for any reason while traveling at speed is a very dangerous situation, the chain won't necessarily slink right off onto the road, I've seen chains get jammed up in the sprocket assembly which locks up the rear tire immediately with no warning. And this was after the dealership replaced the chain and "applied incorrect tension", so even "professionals" can mess this up. Great video but I probably won't be changing my own chain anytime soon, but the dealership also isn't exactly a risk-free option either. I'll just set my set my bike on fire when the time comes for a new chain I guess.

[@johnfox3845]

Also, if you do attempt your own chain and sprocket install, use the service manual as a guide, not this video. It contains multiple incorrect practices and shortcuts.

[@guert2000]

Great video!! I have a question, my r3 is giving me a kick when I fully release the clutch mainly in first gear. Did your old chain gave you that same feeling? It’s like impossible to have a super smooth takeoff.

[@ACProductions77]

just have to know when to let go of the clutch for a smooth transition

[@NoahRoach9214]

Chain is slipping perhaps

[@renripari5514]

IT'S A PROTECTION GUARD , IF THE CHAIN COMES OFF THE BACK SPROCKET IT STOPS THE CHAIN FROM DAMAGING THE INSIDE OF THE WHEEL . KIND REGARDS FROM AUSTRALIA 🇦🇺

[@ACProductions77]

Thank you for the reply on what that part is to bad not all sprockets come with this part.

[@1683clifton]

The chain basket prevents your chain from wrapping and locking up the rear wheel. Don't skip that bro.

[@ACProductions77]

I dont know why dont all bikes have this safety feature

[@Fee.1]

You wrapped it or splurged for carbon fiber bits and bobs? Track bike i assume ?

[@erickquerobines384]

Nice video bro. May i know what type of chain did you used and how many links? I've been watching your video many times. Also downloaded it but all i can see was x-ring type heheh

[@ACProductions77]

i went with the stock setup

[@erickquerobines384]

@@ACProductions77 ah ok tnx btw

[@cflo444]

Nice video man

[@briankeith757]

How many miles did you get out of the stock chain and sprockets? I'm at about 15,000 miles

[@ACProductions77]

Brian Keith I got around 13k

[@briankeith757]

AC Productions I'm doing pretty good then I check my chain about every 300 -500 miles. I'm now thinking ill be able to get about 20k before a replacement

[@ACProductions77]

that's awsome, yes with proper maintenance you should be able to get a lot of miles on the chain. Keep up the good work =)

[@Bryantrincon413]

@@briankeith757 im at 21k now and im now looking to replace my chain and sprocket for my r3 my oem chain lasted a long time i just maintained it constantly

[@AhiaMoTo]

What is total weight of stock front rear sprocket and chain?

[@ACProductions77]

im sorry but im not sure

[@jamesminnock7780]

Yo there if the chain falls off it won't get caught in between the axle bolt and wheel.

[@ACProductions77]

yes thats why its recommended to keep the chain guard on your wheel, I didnt know that at the time this video was made

[@deibyramirez8439]

where can i find the chain & sprocket set for my r3?

[@ACProductions77]

his shop in the south side of chicago in stoney island, he works out of his garage and works on many bikes of all kinds.

[@1683clifton]

If you saw mine after 13k you'd be wondering how I was still rolling! 😅🚴🐢✌

[@Blkvise]

Don’t ever trust those chain adjuster alignment mark they are way off from being properly aligned.

[@ACProductions77]

there is another type of tool used to align the chain I show it in a upcoming video

[@maxpressure1063]

I use the ultimate chain alignment tool... My right eye.

[@jorgepalma1628]

My boss told me it was easy to replace them . Looks like I'ma take it to my machanic

[@ACProductions77]

its easy if you have the right tools
