Chain & Sprocket Replacement | Honda CRF250L

Is the drive chain kinking or the stretch indicator in the red zone on your dual-sport motorcycle? Here I'll replace both the front and back sprockets along with the drive chain on my 2013 CRF250L without any specialty tools. It's recommended to replace both sprockets when replacing the chain to maximize chain life.
Replacement parts needed:
106 link X-ring chain: amzn.to/3OZjim6
14 tooth front sprocket: amzn.to/3bINSlt
40 tooth rear sprocket: amzn.to/3agbHkw
Chain Lubricant: amzn.to/3bYkiZB
(ad)
Tools needed:
10mm, 12mm, 17mm, 19mm, & 24mm wrenches; a 6mm hex socket, 8mm & 10mm deep well sockets (or shallow well with a short extension); ratchet; flat blade screwdriver, channel lock pliers, 2 or 3 small washers, 24mm socket with torque wrench (optional for axle nut torquing); measuring tape or ruler for chain tension; cut off wheel or saw capable of metal cutting; block to cut the chain on; 5gal bucket or motorcycle jack.

One of the best tutorials I've ever seen. I really appreciated the shot of all the tools needed before getting into the video. Montana spring is right around the corner and I'm gathering everything I need to get my bike ready to rip, this video helped immensely. Thank You!

i think this is the best, simple short video about it..
i just did yesterday,,
if i can give advice.. the sprocket form factory,, bolt was so tight.. i actually damage one,, i ordered new so,, .. the hexagonal are rly fragile, you make it round so easly .. so when you force by hand , it just dont work well,, what i did for the 5 other one and it was working directly,, is to hammer the 17 wrench to unlock the thightness .. bolt had 8 years old..
i know some ppl heat them first.. you can try this too,, but dont force the hexagonal one
if it can avoid other noob like me to mess up , your welcome
ahh yeah and i dont talk about the slider. its 2 bit on it,, and its a pain in the ass, that why the man didnt change it on the video,, even if he should.. ,
so check that you buy the good one .. should have 2 rubber bit inner .. and these 2 rubber bit are a pain in the ass to put in the swing arm.. so buy a rubber hammer before ^^ to dont damage the paint on your swing arm,, bcs trust me,, you will need it,,
voila, that was my beginner experience,, 🙂

[@FixandMaintain]

Thanks!
Yes, as you saw in the video, I damaged two of my rear sprocket bolts as well trying to twist the hex bolt instead of the nut on the back side. I can see impacting the wrench with a hammer would help as well.
I didn't change the swingarm slider since, at the time, it still had some wear left on the indicator. However, it's nearing time to replace now, so I'll try to do a video on how to swap it out once I tackle that project.

[@rollingon4673]

Great but Noone has there 10mm. Still haven't found it. I'm not giving up.

[@FixandMaintain]

Haha, true!

[@DoctorFixMaster]

This is a great video. It made my job a lot easier. Thanks! However, a word of caution about parts. You'll notice the original equipment front sprocket has rubberized material on it. That is a noise abatement feature. If you go for the JT Sprockets front sprocket shown here like I did, it does NOT have the rubberization on it and is noticeably noisier (and annoying). :(

[@FixandMaintain]

Glad to be able to help. You are right about the rubber cushioning on the OEM front sprocket for noise suppression. However, in my case, I actually noticed a decrease in overall noise switching to the JT Sprocket with a new chain (mainly because my old chain was so worn after around 20k miles on it). If you want the OEM 14T sprocket, it’s PN 23801-KYJ-940 and can be found on Amazon here: amzn.to/3G3K9Lo (affiliate link).

Thx

[@skytechandgizmosmartinez7914]

great instructions! do you need to measure the torque of the driven sprocket bolts and from the hex screw side or the nut side?

[@FixandMaintain]

Do not apply torque to the hex screw side, only the nut side or else you could strip out the screw. Use a hex socket to hold the screw in place while tightening the nut. Unfortunately, I didn’t have a way to measure torque, since the spokes are in the way preventing a torque wrench.

EVERYONE: "wax based chain lube"
DID: "80W-90 Gear Oil"
It's messy, but one of the few things literally written on the box that isn't in Japanese 😂
Whatever floats your boat, sealed chains don't really care lol

[@FixandMaintain]

I think the most important take away is LUBE THE CHAIN! There's grease on the inside of each link, but regularly getting a little lubricant on the outside of the rings is still needed to extend the chain life.
I personally use the wax based lube because of how easy it is to use. Plus, using it almost exclusively on my old chain (I bought the bike used with 2.4k miles and don't know the prior maintenance history), that original chain lasted 20k miles.
