Lost chain adjuster

Hi!

I noticed today after a long ride that my right chain adjuster plate and nuts are missing. I just have a long bolt with nothing left.

First, I wonder if it may be the mechanic that lose it or forget to put it back, because last time I rode my motorcycle (except for today's ride) was to get my tires changed. I called him and he told me he didnt had to touch these to change my tires and that its not is fault.

Is it true? Is it only a bad luck, or he is lying and he messed up my bike?


And I would like to know too if I could have misaligned my rear wheel or did something else to my bike in my today's 200 miles ride without an adjuster.


Thanks

I'd like to know who he changed the tire without removing the adjuster.

But good luck getting him to pay for another one. I'd say hit @Saabnut up for your parts needs, he's affordable, and quick service

Any mechanic worth his stuff knows they have to readjust the chain slack after removing and installing the rear wheel. With the adjuster and plate missing, the part the long bolt attaches too, which goes around the axle, would have likely fallen out or slid back a ways as it is loose in the swingarm. If it was missing, he should have noticed immediately and talked to you about it. If it was there when you brought it, then he either forgot to reinstall it (not sure how you get away with that as the chain slack has to be set) and half assed the entire job, or didn't tighten the nuts so it fell off and he doesn't want to take responsibility for it. Don't trust that guy with your bike again.

Yes, I do have a few spares. It'll be a day or two before I can dig one up.

Old post hopefully get someone to chime in!! Similar issue I noticed a noise coming from my chain area and saw that my adjuster was loose and beaten up. So I did my best at adjusting for the first time and all was somewhat good....after I get the chain slack where I want it.....how do I tighten back on the adjusters without changing the slack once again? Does this make sense

The first time I adjusted the chain on mine (shortly after I bought it), I noticed that if one of those adjuster nuts ever loosened up, a whole bunch of parts would probably fall off. First I just added an extra nut to each side and double nutted it, but then I realized that a nyloc nut would do the same job more easily.

Nyloc nuts with a 13mm hex are easy to come by, but if you can find a couple with a 12mm hex, then the factory tool kit contains everything you need to adjust the chain out on the road.

They're supposed to already come with a lock nut. Use the forward nuts to make the adjustment, then hold that nut with a 14mm wrench while tightening the rear lock nut to it with a 12mm wrench.

Makes sense, because that would make it adjustable using the factory tool kit. I guess the previous owner "modified" my bike before I bought it, causing me to have to reinvent the wheel, LOL. Not surprising, considering I also found the rear wheel alignment to be out by one indicator mark. Apparently there are people out there who can't count.

Well those indicators arenít that accurate. On my bike, to get front & rear tires aligned with string-test, itís off by one mark. And thatís only way to get tyre in centre of swingarm as well.

After discovering the discrepancy, I did a string test to figure out what was going on. The marks on mine turned out to be fairly accurate. But once its properly aligned you don't really need them . I just tighten the same number of flats on each side to do an adjustment. (Which is why I like the nylocs which don't turn by themselves.) At least the marks tipped me there could be an issue.

Some notes on chain adjusters.
After you use them to adjust you wheel and tighten the axel nut, you must loosen the adjusters and then reset them to the frame by hand then tighten the lock nut to the adjuster nut. be sure there is no tension on the adjuster nut other than to the lock nut.
These things are supposed to be reminders for you wheel setting and not part of the fastening .
BTW nylock nuts are a 1 time use only and are not trustworthy as a adjuster.
