Loose chain? - July 10, 2008, 08:24 PM

I was riding today to work and could hear some clanking around down around the chain area. The chain flexes upward a couple inches. I'm pretty sure that's too much.

If it is, what's the easiest way to adjust the chain. I have a bolt in either side of the swing arm with two nuts. Is it easier to do it on the ground or on spool stands?

EDIT: Found this website. Pretty good directions.

jack up the rear on a stand, loosen those two nuts on the rear axle enough for the rear axle to slide, turn both chain adjusters an equal number of times(I count each half turn, setting up the wrench for a full half twist each time, alternating left and right so that the wheel stays aligned) while occasionally checking the slack until it gets to whatever your manual says is ideal. count the notches on the swingarms, or use a tape measure to make sure both ends are even. once you got the right amount of slack, torque up the axle nuts to spec(you do have a torque wrench, right?) and while you have the bike on a stand, give your chain a coat of lube.

The adjuster bolts likely have jam nuts that get loosened to turn the adjusters then re tightened.

Be sure to check tension again after torqueing the axle nut. If you're going by the slack measurement in the manual pay attention to whether it is with rider on bike or not. If no book then the rule of thumb is 1" at mid chain with rider on board. Chain too tight = restricted suspension travel. Not so good for output shaft bearing either.

Sounds like your chain is pretty old. May think about replacing it. I have heard chains last about 12,000 miles. I changed mine at 20,000 miles though.

Went to go work on the chain tonight.

Got it up on the stand and checked the chain sag. It's really about an inch. But the bottom of the chain does flex enough upwards to hit the bottom of the swing arm. I'm guessing that's what's making the clattering noise.

I'm going to try to tighten it to the point where it doesn't hit.

you don't want it to be too tight either. find out what the slack should be for your particular model and do that. use a tape measure. back in my MX days the universal rule of chain slack was "3 fingers", meaning you should be able to fit three fingers between the chain and the swingarm. I don't know if there's an equivalent in the sportbike world.

doing wheelies will have you needing to constantly tighten up your chain. i recommend at least one per ride, so that you'll get plenty of practice adjusting your chain.

I have to go buy a bigger wrench. That's the biggest pair of nuts I've ever seen.

Without rider (170lbs?) it should flex about an inch and a half or thereabouts. If the chain is stretched (read old - 10,000-15,000
miles) you may want to think about investing in a new one, and check your sprockets while you're at it.

Adjusting the chain should take no more than 5 minutes. Loosen the axel and use the adjuster bolts on each side to move the axle back and tighten the chain. It's very important that you match each side bolt adjustment so the axle is straight on the swingarm, then retighten the axle when it's straight, and set the adjuster bolts.

how about when replacing a chain, is it necessary to have a rivet tool to put the chain on the bike? Or can you just push the rear tire as far forward as possible then adjust back until it's to the correct specs?

You will need to have a rivet tool or a clip master link (which I prefer not to use). Unless of course you buy a chain that is already linked from a mystery supplier and can perform magic and make it pass through the frame.
