Hello im trying to adjust my chain i was riding my bike and the chain got really loose it was tight not sure what happened.. anyways i loosen the axle nut and adjust the chain adjusters then i tighten the axle nut and the chain is very tight any good advise on how to adjust a chain the correct way.. i just wanna get it adjusted right so i dont wear anything out. and if i count each thread adjuster on each side my rear wheel should be straight?

Measure from the center of the pivot bolt in the swingarm to the center of the axle in the wheel, Do this both sides. Wheel should be aligned then. Make sure chain is lubricated good & sprocket is straight, Can't explain it getting tight & loose just by rotating wheel unless the chain has a kink or the sprockets are bent.

Less than 100 miles on all of these.. Vortex sprockets and EK 530ZZZ Chain.. The Chain Was Put On At The Shop Since It Had To Be Riveted On. I Rode It For 100 Miles And Some Reason I Heard A Vibration And Felt And My Chain Was Loose And Stock Chain Guard Was Rubbing Tire... Everything Was Tight Hmmmmm....

i had the same problem it was my rear sprocket where it bolts to the hub the holes on the sprocket were worn causing it to be off center so as the wheel rolled it would go loose then in one spot tight... might wanna check that

It's because when you tighten the axle nut it actually pulls back on the side your tightening it on. Set the chain to be slightly loose and make sure it measures the same on each side. Then tighten the axle nut and it will be just Perfectly tight
With a little play like it's supposed to be. When you don't have locknuts like aftermarket arms do turning the axle nut righty tighty can cause it to move the axle back some because there's no locknut to keep it from moving back further.

You will find that your chain will be tight until you sit on it. Also you will always get slack once you hammer the throttle as well. I am at 64 and lowered 5 in back and 3 in the front. What I do is tighten the wheel until I have about 1 inch total travel up and down( half inch both ways). I use a caliper and measure the gap at the adjusting screw between the swingarm and the axle block. The best way although is to measure he distance from the pivot of the swingarm to the axle. You also want to snug the axle so when you turn the adjusting screws you are getting the movement in one direction. This was a little winded but I think it will help.

but wouldn't that just cause the chain to be tight all the time and not in just one spot? just asking

Its is only that tight when your not sitting on it...but I quess it would be pretty hard to ride like that:s24: The chain has a different geometry when you are stretched and slammed.

i understand a chain being tight when your not on the bike but he was saying it gets tight in one spot when the wheel is on his stand... so lets just say he has the chain adjusted perfect when he is sitting on the bike once he rolls to that one spot his chain is too tight... wouldnt that be a kink in the chain or a worn sprocket? :question1:

What kind of chain is it, also how many miles is On it. It could be stretched in one spot of the chain.

Look a the space between each link make sure the space is the Same. If you got a little space between some and a more than a little in others your chain is streched in that section.

x2 I always have to tighten the nut down before I make my final adjustments to get the chain slack I like!!
