[jerod400ex]

hey guys got another ? bout my ex..... today i was losenin up the bolts on the back of the swing arm to tighten my chain and a bunch of liquid started runnin out..... it ran out for like 5 min any idea wat tht is?

Also i have been having problems with the sprockets feelin like they r slipping..... today i was tryin to make sure the loose chain and wore sprockets were the problem...... i held in the front brake and started to take off slowly and the back by the sprocket was makin a grinding sound but chain doesnt look like it is slipppin at all....... wen i am turnin it gets worse any ideas wat tht might be?

Have you checked your rear bearings ?

Also post some pics so we can see what your referring!

hopefully the rear sprocket is slipping rather than on the other end! can you see clear enough to see if it's that?

It would be kinda hard for your sprocket to slip since its bolted on !!

The liquid might of been water stuck inside the carrier...possibly. There is a gasket between tje pinch bolts that might be damaged.

Ckeck the condition off the rear sprocket teeth make sure they aent damaged. Lastly you should take apart your rear axle as the sprocket hub might be slipping on the splines

all i was trying to say is if the rear sprocket is moving or not, it's either ther rear end or at the crank... you should be able to somewhat feel it on the bike if it's at one end or the other... yes? no?

Yes !

[oxidized_black]

probably best to get the rear on a stand and try isolating the problem. should be able to tell fairly quickly ...

How much tht cost?

[oxidized_black]

if it's the bearings, should be right at the knuckle.

bearings 20 - 60 bucks probably

Don`t do anything until you get a manual on it ! Then you can read step by step on how to do it !! Check it first ! to make sure its the problem !! I`m just guessing on the problem by what i`ve read here !

the liquid came out from under the bolts wen i lossened them...... if its the gasket wat will it do if i keep drivin it..... the teeth dont look like they r damaged any the chain is just real loose i need to buy a new one.....i had it on concrete blocks and had it in second gear id watch the chain on top of the back sprocket and it would bounce and then make a grinding sound.....

good, fairly cheap fix if you figure its the chain!

I have never been successful in running a chain drive on jackstands as the chain seems to load up then unload and makes a nasty clanking noise especially when i let off the throttle. When the rear wheels are on the ground (normal driving) the chain is fine. What am I doing wrong?

sounds likre the carrier bearning is out and causing the axle to run in a angle the fuild is water that sucked in over time

[GEARHEAD01]

ypu sounds like a bearing failure in the rear diff to me too.
