I haven't had that happen to mine. but maybe the adjuster got stripped out a little when you changed out the new tire or maybe the just didn't have the adjusters set up right. It could have been to tight making to much strain on the chain and well the weak spot gave allowing the adjuster to move.

 

Happened to me once. Hopped on the gas in 2nd gear and it loosened up big time. Hasn't happened again though. Knock on wood. It is a safety concern.

 

If you're using the allen wrench that comes with the tool kit you'll never get enough torque on the clamp bolts. Those bolts need to be tight. The service manual calls out 47 ft/lb. No way you'll get that with a 6" long allen wrench.

 

interesting because I used both my 3/8" ratchet as well as the allen key and I can assure you I got it just as tight with both methods. Trust me they arent loose by any means, I would venture as far as to say they are over tight haha

I am slightly less concerned that Im not the only one but that also makes me a little more curious that Im not the only one who has experienced it.
When I did get home I did loosed everything back up and made double sure my axle was lined up perfect and retightened the whole 9yards, I even didnt since the axle down as tight as I had it because when I initially broke it loose I didnt find it near as tight as anticipated.

Beat it a little coming home today, didnt hop the clutch yet, maybe tomorrow or friday when I have the day off.

Anyone else please give input or your experience because I dont want to have to go back to the dealer and say hurtful things...

 

I had the same setup on my 92 zephyr 750 and never had a problem or on my 2010 Z1000. Maybe you got some grease or something on it to make it slip. Did you get the axle tight?

 

that's a lot of torque on the fasteners. I torque bolts all of the time at my work and they are only in/lb for most of them. I'm going to look at my manual and see what it says. That might be the right torque.
But one thing i know your not going to get that with a 3/8" ratchet. It just doesn't have that high of a torque value to put on a 8" ratchet not unless your super strong.

 

I agree. That's why I mentioned not trying it with the tool kit allen wrenches or for that matter a short ratchet. I doubt you can get there since the clamp bolts would require a 94 lb pull on a 6" long wrench. Good luck with that. :lol:

But those are the specs spelled out in the factory service manual. I thought maybe it was a misprint so I checked the specs for a 10mm bolt. 10mm, grade 10.9 torque spec is 47 ft/lb by every table I could find so I believe the FSM is correct.

The axle torque doesn't seem excessive given the size of the part.

 

very true there JSharp. I looked into it also and you were right. Seems like a lot but i'm sure they manufactured the bike to the torque values that you listed.

 

Can I get some popcorn?

 

Ive not had any problems that you describe. I am a pretty aggressive rider.

 

i ground off the nub for abs on my 11' and rotated 180 to get some height in the rear end for better tip in. mine gets beat pretty regularly. never experienced this issue

 

Thanks JSharp.

If anyone is still interested, ripped 2nd gear on my way home, nothin to brag about, but didnt have any odd feeling, no loosening of the tensioners. May give 3rd a go again tomorrow. This was after about 15mins of riding in ~80* weather, starting to think temp/riding time had a play on my mishap (I.E. metal parts not expanded)

 

that could be there Silv. Just wondering have you took everything apart again or just tightened everything up from when it moved the last time.

 

yes after the second time I loosened everything up, re-aligned it and re-tightened everything. Key factor I think was bike was stone cold, had been sitting in the garage all day and didnt get over ~75* that day

 

All those parts fit pretty close, they might be worse when it's cold. It makes you wonder if something wasn't bound up and you fixed it by straitening out the alignment.

When I got my bike the adjusters weren't aligned. So much for dealer setup...

They can just sell me mine in the crate. :lol:

 

at least you got it fixed and it hasn't happened again. It could have been a bunch of factors but like i said it's good you got it fixed.

 

what's going on with the bike now?

 

2015 Z1000 and this has happened to me twice in the space of 2 months.
Very concerning.
Has there been any re-call on these bikes for this issue??

never seen this on my '15 z1000 .
