Chain falls off....

[Narly R]

All these threads makes my bike look bad!:(

But when i like spin a cookie in the sand it will fall off or like land side ways, any movement that causes my swing arms to have presure loike that. But my chain prolly moves like 2 1/2 inches, I have to tighten it, but still I think my swing arms is moving...:ermm:

check your bearing in the front of the swingarm and also the bearing in the axle carrier. It sounds like one of them or both places are bad.

2 1/2" of chain slack is way too much!
On the 400ex it is recomended to be 1 3/16" - 1 9/16"

May need to remove the carrier and clean out the swing arm of dirt and grime then reinstall the carrier. Not hard to do.

I have new carrier,bearings, and bushings.I need to check for loose bolts and tighten my chain. I think that'll get the job done...:ermm:

Ya check for loose bolts, and check your shock linkage very well I had a bot come out of there and do that.

Other than that I would say your needle bearings are wasted.

u should try to tighten ur chain, if that dont work, change ur swingarm bearings if that dont work, check and see if ur frame is walled out, if it is, take a washer, and have a welder weld it on to the walled side and u should be good, we did this to my friends 250x, and it is still working besides the motor

jeez dude. How come this thread isnt for r experts only??? lmao. Well i think u need a new chain or need to tighten it. I run about 1 to 1.5 inches in my chain
