New Sprockets or just Chain

[MMH]

Definately need a new chain. Should I replace the sprockets as well?

[travis dasher]

Is this a serious question?

Yes, replace both the front sprocket and the rear and the chain at the same time. That way they will wear evenly.

Yes, it's a serious question. just getting into this stuff, and have been reading alot, but still finding many different opinions out there.

They look in pretty good shape.

serious question... yeah right, never seen what a new sprocket looks like?

I can replace "a ton of other stuff" but would rather replace what needs to be replaced. Yes, my bike has been beat on, but the head & rear suspension seem tight, the valve lash is right & not moving, the wheel bearings seem OK, etc. I got the bike last year for $2700 and have not spent alot of money on it. I can replace everything underneath the handlebars, and, if I do it myself I can probably spend no more than $5K. Oh wait, if I wanted to do that (spend $7700), I just would have bought a new bike.

It was a serious question, and I am looking for serious replies to this specific question. Not the rest of the bike, not if I'm serious, not about my wife, etc. Please stay on topic.

I do believe I gave you a serious answer. I told you to change your front and rear sprocket and your chain. Your chain actually doesnt look bad, but like I said replace them all so they wear evenly. Try motosport outlet they have combo sprocket deals, they also have tougher skin. Get the combo deal and some tougher skin and you should qualify for free shipping. Hope this helps

Seriously, replace BOTH sprockets AND the chain. That is one of the most worn out rear sprockets I've ever seen. You must replace all three, and I would do it before your next ride. No question about it. Anyone who tells you differently is not a friend.

Yes as stated you should replace the chain an both sprockets. I honestly don't know how the chain isn't slipping on the sprokets. I also don't think travis dasher was being smart or anyone else that aswered your question; it's just that your pics are very clear and show lots of wear. They may have thought you were joking or stating the obvious. You then cleared it up by posting you didn't know alot about the matter. I am new to this site myself but it seems like most are here to help. Good luck and shop around to get the best deal on a complete set.

You did give me a legitimate answer - thank you. My last response was directed more at joman2055. I was intending on getting a front & rear sprocket along with the chain, but did want to get some opinions on this sprocket - would it accelerate the chain wear or not. I always heard that bad chains wear out sprockets and not the other way around (although it is always best replacing sprockets and chains at the same time).

Tougher skin? You talking about me or something that motosports outlet sells? If me, I got tough enough skin, just wanted to keep the thread on topic.

[travis dasher]

If you use the same chain on a brand new sprocket then the sprocket will look like the one you have now in a few months.

I did think you were joking and stating the obvious when you asked if you should replace the sprocket. I apologize for being sarcastic.

You should replace all the components: chain, sprocket f/r. If you are looking to conserve a little cash you can measure your chain to see if it is worn beyond the service limit.

Measure from pin to pin a total of 17 pins. Make sure the chain is tight with no kinks. If it exceeds 10.2 inches or 259mm then you need to replace. If not then you could still use it. If your chain is still within the limit you can get sprockets cheap.

Front sprocket check out Turner, like $9, rear look at JT or Turner from $16 to $25. They are both steel but wear well.

I wanted to try a higher rear see how it felt but didn't want to spend huge $$ so I got a JT 50 (std is 48) for $16.99 thought if I liked it I would upgrade but it has worn so well I just left it on.

your going to have to put a chain and sprocks on that and look at your chain plastic, the swingarm buffer and the rear chain guide, look on the bottom of the chain buffer, (look up rite behind the shifter) your going to need that stuff too,i cant even imagine what the rest of your bike looks like!

[MMH]

Thanks to all that responded. I kind of knew that I should replace all three, but just wanted to check.

The cardinal sin of dirt bike wrenching is to work on a dirty bike. Take that poor bike to a carwash. Most people wash their bike after every ride.

BTW, you needed a new chain and sprockets about 20 hours ago. You are lucky you haven't already thrown the chain into the engine case.

holy craaaaaaaaapppppppp!!!!!!!!!!!!!!..........i ran a did oring with sunstar sprockets for four years and they still looked new!........i can not belive what i just saw........those sprockets should of been changed 500 hours ago!....geeeeeezzzzzz

I wanna see what the rest of the bike looks like... post some pics of it..

Always replace both sprockets and the chain together as a complete set and be diligent with the adjustments and maintenance. It's the only way to get the full service life out of them. ?

I also wholeheartedly agree with CamP. It's a lot easier to maintain and inspect a bike that's clean, it'll save you a ton of time, money, frustration and even injury. You're just getting into this and that's a good thing. Welcome to the psycho ward. You also came here seeking information and advice and that's a wise thing. We all started out knowing zero about bikes and we all learned from others who had already learned it. Some of us even payed attention. ?

I'll reiterate the advice that CamP already gave you. Don't ever let your chain & sprockets get remotely close to the amount of wear that your current set has. Not only are you at risk of major damage to your bike, but that's a situation that could get you seriously injured or even killed. The last thing you want is to be airborne or at speed and have that chain come unglued and wad up on you.

The only way to have fun riding is by riding. You can't ride if you're in a body cast. Or a coffin.

Be safe. It'll keep you in the saddle. ?

That was an awesome speech!!!!

You should go into politics...........................?

Nicely done.

I am astounded that that chain even stays on that sprocket. Never seen a sprocket that bad!
