Riding around for ~1000 miles with loose pinch bolts

[Duc796canada]

Ouch, that is scary! I have been over servicing my chain then, I have own dirt bikes and we lube the chains every ride, so i have been doing my monster's chain every second or third ride regardless of mileage, I will cut back On another note, people should " pre-flight" their bikes we do it before going flying, the onus is on you that is getting on the motorcycle and or aircraft, the mechanic or technician is not going to be with you when a mishap happens that could have been prevented with a simple "pre- flighting/walk around" on your machine. To make mistakes is to be human, technicians are human.

i dont know guys... these bolts are supposed to be greased, and torqued to 33nm (~25 ft.lb.) in a 1-2-1 sequence. that's a pretty tight bolt.
i've ridden my S2R for AT LEAST 1500 miles without adjusting the chain (it was lubed more frequently), and never in a million years would I even THINK that these bolts could come loose. Had to be improper re-installation in my opinion. they weren't torqued properly, and damage was done.

As a mechanic working on something that is responsible for somebody's LIFE, you don't just ASSUME that this guy is going to check his chain in 300 miles. you torque that shit down right, and then you check it again, and then you check it one more time before it leaves the shop.

is the mechanic responsible? think whatever you want.
Could the RIDER have caught this issue earlier if he checked his chain more often? Yea, obviously.
is the RIDER'S FAULT these bolts came loose because he didn't check his chain stretch every 10 miles? no way in hell (IMO)

OP noticed his chain looked loose, but did not take action.  It's not that he didn't check often enough, but that he ignored a problem.

If the story was "About 300-600 miles ago I had my bike serviced.  When I went to oil the chain, I noticed it was a little loose.  Upon further inspection, the eccentric's pinch bolts were loose.  Should I be mad at the mechanic?"  Then yes, mechanic's fault entirely.

we're saying the same thing here.
OP shouldnt have ignored the loose chain, that's fair. but it was someone else's ignorance that caused the problem to begin with.

I didnt post the thread just to complain or point blame. Just wanted to address the issue and ask for options of anything else that could have been damaged. Other posters turned it into "You shouldve caught it sooner". Fair enough.. but I didnt.. oh well lets move on. Still, in my opinion there is no way those bolts could have just rattled loose, and just because I didnt check it a bit sooner, doesnt change the fact that a dealer tech didnt tighten the bolts. But whatever..

Have you pulled it apart to check for damage yet?

i'm literally amazed by the fact that you WERE able to ride with them loose...

as stated, the eccentric hub was likely twisting to a certain degree in each direction, but it would really only be on stop/start and hard accel/decel...
see any metal shavings in/around the hub area?

there's a guide for removing the eccentric hub in the tutorials section.

i would certainly pull it out and have a look.
best case, it's fine and you did some work but at least you know...
worst case, it's all ground up and you need a new one.

If you DO need a new hub, at that point what I (emphasis on I) would do is contact the dealer and start talking about compensation for replacing the hub. The hubs pop up on ebay, the classifieds here, and www.gotham-cycles.com occasionally in the $150 - $300 range.
