If I thought I could find something in that tensioner to figure out it was just a straight washer with a wave to it now, I'd send it back to BAD. He can tumble it in his hands and find out. I was just going to Meguyveer it MY WAY! I want to know why my tensioner took a shit the second we removed that bike off the dyno. I had that rattle going but it is no way as noisy as that 2010. Something let go, blew out, or ???, I'm no engineer that designed it.

For all I know, it could backup on shutoff like it does and that tensoner is there to zip that up like a fly. I would have to throw the clear crank cover back on again, watch the shutdown, slow-mo the stop. If the crank moves backwards, we know the oil pressure was off on the key fob stroke. What moved that chain back could be the cam lobe trying to come up a ramp but is pushed back by the valve springs.

Could be instant. Could be overnight, could be walk away, come back in an hour the slack is in the front now. Only that window covers knows for sure and I don't care. My chain is not chewing itself up when I see that crank sprocket exposed. It has a brand new look to it. No silver shin like it lost the flat off the round. Now the gear tooth is polished, but that polish is wear on both chain and sprocket.

You get a runner with the noise gone, you can't tell if you pushed how many pounds of inch on that slipper arm? I'm trying to point out a lot of points to chase on the static approach and you are on the running approach. YOu have no clue of high spots in the chain so you bit into a slipper on one rung, the other rung comes around loose is a goose is you don't get it!

At the end of the day, I have no clue what causes what in this world. That says it all right there you time 3:33 to 3:44 you tell me what is going on in your world.

Well,anyway...I think we can both agree...the chain slap is most likely making noise as it passes down the front run of the case there.My only point about the slack,is that if it's making the noise at the front,then the tensioner at the back is correcting it.Whether it takes 2 seconds,or 2 hours.The tolerance of the tensioner,whether manually or hydraulically adjusted CORRECTLY will not harm the chain or put excessive pressure on the shoe.The manual adjustment is doing exactly the same thing as the hydraulic one...MINIMAL force to a LOOSE area of the chain.When the tight side comes around,it won't be touching the shoe anyway(or barely).That's my take on it.If you get that tensioner in there and crank down,you're gonna definitely damage something sooner or later.Still friends?

Are you "Still friends" is put words in your mouth about a stupid chain function? You mean, fun junk? I'm having fun talking about a squid redesigning an old Z1 static tensioner is remove some brilliant engineering with give on lift, tight on drive?

I like watching you move your bike all back to stock again, blue. WOTar friends for? Slice of Pee Saw ya coming so I ordered more.

wowerman: I bought this bike last Sunday.I did not pay attention to it. Is normal rattle (2 sec) after relasing start button?It does not occur every time.
I know older Jap bikes had something called free wheel or whatever.Is this it?

That rattle has to do with the cam chain tensioner which is actuated by oil pressure.

After my 2006 14 got ~ 3500-4000 miles on it that rattle stopped.
