My chain has been making noise most likely since the first ride of the season. I never noticed till I ran it on a short ride without earplugs or helmet. Quite noticeable.
I readjusted as per service manual (20-30mm (closer to 20mm)) with the chain at the tightest point using the side stand. After putting bike on a lift that measurement is 30mm. At its most loose point its 38-40mm.
After a spin around the block the noise is still present.
I put a dial indicator on both sprockets teeth (O.D.).
The most they’re out of round is 0.015”.
Measured the chain (321mm per 20 links max) and found no link set longer than 317.8mm. That was 50 different measurements (112 links, every other link).
The “tight” spot is always in the same place, telling me it’s the rear sprocket.
If the o.d. of the sprocket is “true” to the axel. Is it the root depth of the teeth changing?
Next question is where do ya’ll buy your sprockets from?
The chain I’m going to buy is a step up-D.I.D 525ZVM-X Nickel Super Street Chain
oh ya my chain is cleaned and lubed religously

Eddy is great but I get mine from my dealer. After the mileage I got out of the first set with no lube at all I feel it well worth the money. I got around 23,000 or so out of the first set and really didn't need to change it yet when I did. I was just starting to have to adjust more often so decided to change before I had an issue. Both sprockets were still so good I probably could have slapped a new chain on and been fine,no visible wear on them.

UPDATE:
Had a buddy over and explained the situation with the chain being tight and loose.
He checked everything I did and found the front sprocket the culprit.(He found more tight spots than i did in one revolution)
I think I was over thinking the problem with rulers and calipers and dial indicators.
It’s still on the bike so it’s hard to really see.
What are the chances the output shaft is bent?
My friend doubted it.

Chains are pretty noisy if your exhaust isn't louder. I doubt anything is bent and the mileage seems low enough that chain stretch shouldn't be an issue. How many teeth up front?

Since you are already familiar with checking for run out via dial indicators you should be able to answer your own question as to output shaft trueness or endplay. I have found with my '06 that with a true parallel alignment that I would have to install an .018 thou. shim behind my front sprocket to attain the closest to a perfect alignment attainable compensating for the existing runout on that particular bike. This was ascertained by a precision ground 48" straightedge. My '05 is so close (.002) in this respect as to not being worth mentioning. Chains are noisey, no way out.

Was some slight rust spots on the outside of the outer link plates but that's all. Nothing that would effect anything.

hey RYK. YOU shimmed a sprocket 0.018",,,your more A-Nall than I Did ya use a "Rule" or somthing machine ground? A 48" steel rule is 1" wide,,,,,,,,,,,,,,, There I go again  I'm investing in 'Motion Pro' chain alignment

18 thou. over that span was causing premature chain and sprocket wear and yes I used a 48" ground straight edge (Starrett) along with a matched set of parallels so I could jump the frame, there is always a way, if you think about it objectively. BTW, to be an alignment guy by trade, it actually helps to be anal.

I keep the company of more than one Millwright... mostly through friendship. I hear stuff, I assimilate stuff, but I'm gonna have to run THIS one by them for clarification!!

Yea Keith, whistle chasers from sawmills or qualified machine erectors of which fraternity I belong to? There is a difference.Whistle chasers get the mill running as quick as possible, sometimes with ingenious albeit band aid fixes, construction millwrights build the sawmill in the first place, so the whistle guys can get a job.

My bike used to make troublesome little noises. I gutted the pipes and now I don't have them anymore :-)

Ryk,,,,
Did ya use the parallels before you put the chain on(sprocket to sprocket), find a reference measurement. Then assemble with chain and measure off the reference?
There can not be a hell of alot of room with the chain on, with a parallel, on the sprocket together.
I have the same tools available to me (no laser) but i'm having a problem picturing the set-up in my head right now
with the chain on the bike.
I don't mind spending the extra time fine tuning if the tools are available.
it's not A-Nall to me, it's the challange
thanks,Les

The noise? Like when you are close to a high curb or a barrier on your right you hear the chain washing over the sprocket. That kind of noise?
Chains make noise, it doesn't mean they are broken.

A nice set of Bubs and a snut fitting helmet= no chain noise.

I had the bike on a stand, chain, guard and shocks off and new sprockets installed. Raised and lowered jack to get the best access to sprockets with the rear tire on the floor. Then ascertained the points to attach the parallels to my straightedge ( marked with a sharpie), I attached the parallels with duct tape so as not interfere with readings (it will be obvious where the tape needs to go), established best possible parallity via the chain tensioners and established with a feeler gauge that my input (front) sprocket needed 18 thou shim behind it to come as close as possible. BTW,I took 10 readings, noted each one, averaged out the values (spun the sprockets 90 degrees each read). Rarely will these kind of alignments come out perfect, but the harder you try, the closer you will get. We now use Lasers a lot now in industrial apps. (Rotolign & Optilign) but the old ways still have validity, IMO. This all came about because at 6000 miles my chain and sprockets were shot. When I installed a new D I D chain and new sprockets the chain refused to center on the rear sprocket, it would hug toward inboard side of the rear. Coincidentally the wear on my original rear Spr. was on the outboard side and basically validates the misalignment I found and re mediated, did I leave any thing out?

I follow what you have done. My Q.C. guy is leary on letting a $700 parallel outside of his eyesight. He's on vacation next week so I don't see a problem with him being Concerned too much. Q: Did you adjust your chain slack with your swingarm at it's longest point? Or as per destructions/Triumph? I ask because my new chain (D.I.D. 525ZVM-X chain) shows a diagram with the swingarm at it's longest point and then measuring the total slack pushing up AND down

I adjust the chain slack with the suspension loaded (rider and gear aboard) and the bike upright. My son, also a millwright, measures the slack for me. I can measure this out myself, but quicker and more precise with a helper. As to your question as to which method I follow, truthfully, I don't know, I never read the instructions, maybe I should? I might learn something.

I'm having a machinist make a set of Parallels that will 'bolt' on to both sprockets(driven and driver)extend beyond frame to wit(?) another parallel,,,,,,,,

I used to overthink this chain thing too...Im at 51,000 on my 05, replaced the chain about a year ago, and I noticed the chain "flopping" ALOT. Took the countersprocket (front) cover off, and put it on the jack, cranked it up and put it in first gear, and sure enough, flopping terribly. By rotating the rear tire through, you could watch the chain "kink" as it came off the front sprocket on a couple of links. The links that were kinked, were SUPER tight and very difficult to straiten. 2 pairs of vice grips on either side of the tight link, and ALOT of penetrant kind of fixxed it, but they're still very tight. Other than that, chain is still new. Not gonna worry about it, just ride it. It is a DID X-ring chain by the way. Won't buy another one!

I miked and carefully cut one out of a Stainless "D" sized Aloma machinery horseshoe shim I picked out of the garbage and packed home from some stinky papermill sometime back in the '90s I think. You need 15 thou? That size shim stock is readily available at the bearing houses . I used a small compass to get my layout, you need not cut in the splines, just an even, tight fit. Mine looks like a sheetmetal donut. Brass stock will suffice just as well. Keep It Simple
