clicking noise coming from chain/rear sprocket?

Hey there,
I adjusted the tension on my chain a few weeks ago, and everything was fine. However, I have since noticed a regular (but not exactly periodic) clicking noise coming from the rear of my bike. I did notice that after I adjusted my chain, the silver adjustor bracket on the sprocket/chain side that holds the adjustment screw is canted inwards towards the rear sprocket. I thought it might be that the bracket is hitting the nuts that are on the rear sprocket, but that doesnt seem to be it. I can't quite figure it out. Does this look wrong? How can I nip up the rear axle nut without canting the chain adjustment bracket towards the sprocket? It's definitely not at 65 ft-lb's like the manual states. Thanks!

Three things worth checking:
1.Silly question, but did you remove the rear wheel? If so were the wheel spacers put back on?
2.Another possibility, the screw that goes thru that silver adjustment bracket has a small circlip, if that fell off, you may be tightening the screw directly into the end of the bracket, and thus bending it inwards.
3. The front or rear sprocket is worn, and the chain is jumping on a worn sprocket tooth. I once had an intermittent clicking noise, coming from 'somewhere down there'. Drove me nuts. I changed the chain and front sprocket and it was solved.

I've adjusted chains and have had clicking noises come and go over the years. I just check things a once over to make sure nothing is falling apart or about to fall off.

I just got done with one of my bikes making a clicking noise, readjusted the chain and it went away, go figure.

A close-up photo would help, or use this one of mine to point out what you think is wrong:

How much slack did you leave in the chain? Bonneville T100 supposed to be 20-30mm of slack at the midway point along the lower run...measured at the tightest spot on the chain and with the bike on the sidestand, not the centerstand or on a lift....so that some load is on the rear suspension.

Chains tend to make noises when it's time to replace them and or over tightened. How many miles on your current chain?

TTP Tune#3, NH Toga's, Bitubo shocks, D9 bracket, sonic fork springs-90kg, 19 toother, smoked blinker lenses, FP stealth levers, Dime City steering damper, Motone brake relo bracket, gaiters, front fender stay, shock bolt dress up, OEM grab rail.

A clicking noise is also produced when the nut that holds the gearbox sprocket is a little loose. This is fairly common, even with its tab security washer in place. Remove sprocket cover and check that.

Make sure to check your bearings too

I remember early on people found primary sprockets loose on these bikes. Have not noticed that post lately, since the bikes went over to Thailand.

I have owned Bonneville's assembled in England and Thailand and have found the Thailand bikes to be better sorted.

Had a similar noise recently. Turned out to be sprocket carrier bearing. Cheap & easy to replace all three bearings.
