I've owned this dirtbike for 5-6yrs and sadly I've never been the one to work on it thanks to school, work, and other things.
I recently moved from seattle where I paid my friend a good $150 to fix her up alittle so I could sell it once I got back down here to GA.
He replaced the chain for me but he didn't take enough links out of the chain and when under heavy acceleration in a high gear (3-4-5) the chain just spins!

Can anyone give me some good advice on properly adjusting the chain and what steps I should take! Thanks for the help!

you should be able to move the rear wheel back on the swing arm.

im not sure wether this will be enough to gt rid of that amount of chain hang or not.

the cahin might just be too stretched. u probably should just buy a new chain.

The chain is shot. You can get a new one for cheap. Try eBay or RockyMountainMC.com.

Ok! I had a feeling it was pretty bad!

Can anyone let me know how to adjust one anyway as I'll more than likely have to do that when I get the new chain in! Thanks

Ok. see that strange looking silver thing on the axle bolt there in the first pic? Loosen up the axle with a ratchet and a wrench get your new chain on there then turn that chain tensioner on both sides of the bike so that the wheel is tracking straight and the chain is tight. Don't make it so that the chain is actually taught though, there should be a little dangling on the bottom side but obviously not enough to let it slip, thats pretty dangerous dude.
I've never actually seen a tensioner like that but I'm guessing its eccentric and as you rotate it counter clock wise it will slide the wheel back in the swingarm. Good Luck

my opinion. just grab a new chain. that one looks a lil beat up. if you gave me the length of the chain and all that good stuff..i could possibly find someone with a spare

I'll see what I can do in the next couple days! Look out for a PM from me!

The chain and sprocket are shot. Buy them as a set, tell the deal what bike it's for and they should be able to get you the right length of chain. Of course to install a new chain you need to rivet it, and that requires a chain rivet tool.

I would suggest you take the whole bike to a shop and have them do it. Unless you have done a chain and sprockets before, you will need supervision. The first one is a bugger, after that it gets easier. Because the chain spun, your rear sprocket is done, your fron may be OK, can't see it in the pics of course, but it should be inspected. If the teeth are rounded (likely) it's cooked. If the teeth are knife edged, it's worn out. They should have flat tops, not round or sharp.

You can get chain clips that will allow you to replace a chain without rivets but my experience with them has been bad. Nothing quite like having the clip come off and shooting your chain out the back with great velocity. Of course it only happens when under load so they do go flying off when it happens.

I would strongly suggest taking it to a shop and having it done right.

I just re-read your post and it says he replaced the chain?!?!?

That chain has seen action. It's got old lube gummed up in the o-rings and rust on the rivets. How long ago did he do this work for you?

If the chain is new(ish) then drench it in kerosine and get the gunk out of the o-rings. If it's so lose it's jumping teeth then you likely don't have enough adjustment to tighten it enough without taking links out. You should have 20mm to 30mm of play, no more than that. Certainly no less than 15mm.

Is that a 520 chain? No, seems smaller.. Maybe a bit less play would be OK, but certainly not taunt (as mentioned before).

Good luck with that.

Thanks for the advice everyone! I was thinking about just breaking down and getting both sprockets replaced with the chain because it clearly needs it.

The chain was all re-done in Oct of 05 but the bike has been sitting for awhile! Also, because our 3-car garage hasn't been built yet, it's been catching hell from the atl heat and random heavy rain and thunderstorms!

chain is bad, but if you are having "chain spin" you need to go ahead and rpelace the sprockets too, the chain should never "spin" on ocassion when it has alot of slack it will jump a tooth. i've never heard of it spinning, because it would shear off the teeth. i would also look into getting a new clutch, it's about a 20 minute job and roughly $100 for the clutch. i would guess if you're "spinning" it's the clutch and not the chain.

after looking at it again, there's no shiney metal on the sprocket teeth or the chain, if you were jumping teeth there would be alot of that. i would look into getting a clutch. the best way to test that is to take the bike up into say 4th or 5th gear (depending on how torquey the bike is) rev it up WOT and drop the clutch. if it lugs forward hard and dies (or almost dies) it's not the clutch. if you drop the clutch and you hear it die down a bit, then rev back up without jerking hard then the clutch is shot for sure.

oh check your front sprocket too, those teeth could be sheared off.

It's allways a good ideal to change every thing at once, Because the sprokets and chain allways wear evenly, So you want to keep them all at the same wear point If you throw on a new chain and the front sproket is worn a bit, it will rost the new chain in record time.


Also over time the chian will stretch, to adjust simply losen the rear wheel axle botls ans move the tire back. till the chain tightens up, then retighten the bolts.

On my HondaF4 there are little screws that makes moving the wheel back and forth a snap.

But i can't see you axle in that pic.

what year and modle of bike is it?
