Sounds too tight.... What was your tightening process? On the side stand? Above all don't ride that thing until its adjusted...please

make sure not to over tighten the axle bolt. Chain should have about 3/4" of play without a load on the rear.

I have bike on jack, get appropriate chain slack (I think), tighten axle and then tighten chain tensioners. even when I don't think axle is tight enough, tire will not spin freely. also, when I keep tire centered it rubs chain.

I tighten chain tensioner after axle. as soon as I tighten axle, wheel does not spin freely.

Did your bike fall into gear preventing the rear wheel from turning? |

Did you grease the bearings? There is very little to no grease from the factory. The bearings are very simple to grease. You will need to remove the seals. After your remove the seals just pop the bearing covers off and grease them up. Rotate the bearing to work the grease in there before you replace the covers. Do the same for the front. Your bearings will thank you.

as soon as i start tightening the tensioner first (even just a little) i seem to lose the slack in the chain. i have read 3/4 to 1 inch in slack. is that measured from bottom of chain or from bottom to top of chain movement? if i am missing a spacer, would it be on the brake side of bike? i have not removed the tire, but will too grease bearings. thanks for photo of that!!!!!!

There's a spacer on the sprocket side. Once you have the slack you want and the chain is aligned then tighten the axle bolt. I just snug up the chain adjuster lightly so that it's not pulling the axle then use a 2nd nut as a locking nut so it doesn't vibrate loose. This will keep the axle from moving forward once you put a load on it from riding. Like stated before try to line up the center of the tire with the shock mount. That should get you close on chain alignment.

I would guess missing sprocket side axle spacer at the swing arm, but let us also not forget that sometimes they goof up at the factory when installing the rear wheel bearings sometimes.
As far as tightening the axle itself, just make sure you don't go too tight. 35ft-lbs is all it takes.

I had to move my axle as far forward as possible with the chain tensioners completely loose in order to get sufficient slack in the stock chain when I installed a 17 tooth front sprocket.
Assuming you have the spacers properly installed, keep everything loose and push forward on the wheel while keeping it centered and tighten down the axle nut, then come back and tighten the tensioners afterwards. |

first, i want to thank everyone for all the very useful information!! it's pretty cool that there are people so willing to help out.
now, this is what i did. i removed tire and greased bearing (hardly any in there). put clamp on chain right behind chain guide (which doesn't seem to do anything) and tightened it a bit. this was the only way i could get chain to keep slack in it. every time i would tighten axle, chain would tighten up. i made sure axle was pushed up all the way on the chain side and had to tighten tensioner on brake side a little to keep tire from rubbing chain. this took me 10 or so tries to get it where i wanted it. tire appears to be center with base of shock bracket and barely misses chain, but misses. tensioners are not tightened equally, but everything else looks pretty good. tire spins freely until caliper is bolted on. this is causing the tire not to spin freely. i only have 50 miles on bike and am hoping once pads wear down a little it will loosen up some. i don't have any problem pushing it around while in neutral. thanks again!!!!! |
