slow-mo chain throw
 

was looking at some videos from someone over at cycleforums and saw this. Holy schnikies scary

I've lost chains and gotten flats while riding at speed. Having a chain come off is pretty much a non-issue as far as safety is concerned . . . . unless it gets wadded up and locks the rear tire. Getting a flat at speed is frickin' SPOOKY!

Where is the part that I'm supposed to be impressed with? Looks like the fuckin chain just fell off.

Im a pussy, I imagined it going into the engine and locking up the rear.

When my chain broke, it got lodged in the bolts that hold the sprocket to the cush, wedging itself against the swing arm, and locked the rear at about 50 mph. I kept the bike up, but it was all over the road. I wasn't on the gas, just cruising at about 50 or so, and it let go. It took me and 2 other guys on the side of the road to get the chain out so I could roll the bike around.

This was the stock chain with about 12K miles on it.

I had a similar thing happen too, except mine was the stupid adjustment plates that kawasaki uses, one of mine snapped, pulling the wheel to one side, locking up the rear doing about 50, scary shit

When i thru a chain on my 9R it was at about 70mph and it just spit out the rear like a snake... it took out the tire hugger and rear tail section as it was sucked into the front sprocket where it took out the sprocket cover, speedo sensor, and water pump. But I just coasted to the shoulder.

When I imagine a chain coming off, I see it separating right before the rear sprocket, lifting off as it comes around and slapping my lower leg before getting spit out the back...

But I don't know if that is physically possible as it would have to bend a certain way under motion to actually reach my leg.

When the chain came off, I wasn't sure what had happened. The bike suddenly revved and it was like I had shut the throttle. The bike started slowing down real fast like I had geared down about two gears. I was doing about 50 or so I think. When I pulled over I could see the chain had bent the guard into the tire and was melted around it. Could have been a lot worse!

I have recurring nightmares about this happening, especially after replacing chains

Man, we have had this discussion....


I know that it happens but I really can't wrap my mind around it. Every time someone loses a chain they,

A. ALWAYS claim that the chain and sprockets were perfectly maintained and that the chain was correctly adjusted.

B. ALWAYS claim that the chain was correctly installed using a rivet link and the proper tools.

C. ALWAYS claim that the chain wasn't showing ANY signs of wear, kinks nor was worn/stretched out.

I have never honestly had this happen nor have I personally seen this happen. I am FAR from being a chain maintenance fiend. Heck, I maybe, lube my chain every oil change (no bs) or when I want it to look good. :lol: I definitely don't adjust it much, maybe twice a season or when I change the rear tire. In fact, almost never other than tire changes and not always then.:idk:

The o-rings seal the grease in your chain anyway. The only benefit I can see to lubing and cleaning it is to stop corrosion.

Wait...omg...we AGREE on something! Shit, get your loved ones, this was the 7th sign of the apocalypse!:lol::lol::lol:

What is this chain maintenance you all seem to talk about regularly? :idk:










:scared:

It's to keep the o-rings from drying out.

I believe they're made of Nitrile. And I don't understand how they would dry out.

Just be careful what you use to clean it. Gasoline and carb cleaner make the o-rings swell and degrade.

Friction from rubbing the plates, heat cycles, weather, dirt, sun bathing and so on.


If you want to buy a new chain and never lube it to do a test then do it. Make a short vid everyday.

I dunno about all you scientific experts and stuff, but I was laways taught that a chain needed to be lubed, I've never had an issue or short life with a chain that I've installed.

The only 2 chains that I've installed that needed changing both lasted over 20k so I was happy with that. The other chains, have had the bike replaced before the chain.

My method, spray the chain after riding in the rain or though lots of puddles, also spray when I remember to spray it, leave the chain just a little on the loose side, adjust it as needed usually around 3-4 thousand miles, clean it off with a rag once in a while.

Just to clarify. I'm not saying don't lube your chain. I'm just saying that most of the protection is already there.

A LOT of offroad riders and dualsport riders don't lube their chain due to 1. like Tsmall said, the lube is already there and 2. the lube just make dirt and grime stick to the chain wearing it out faster.

I've had two chains on the DRZ in 21000 miles and I cleaned/lubed them once a week.

a fellow DRZ rider down here only rides off road but has about 10000 on his chain never lubed... just cleaned...

YMMV

And here is a good write up on how different solvents effect o-rings in a chain.

I think I've lubed mine a total of 3 times in 13k Miles. So far so good...Although I think my clutch is on its way out.

The clutch is just the way your ride, If I remember correctly, your bike only has like 30k on it

Lol...I wish I had 30k on it.

It has 13...But Ive taken it to the Dragstrip a half dozen times...Getting the hang of launching it and slipping the clutch out without hurting it is something I didnt get the hang of immediately. But I know I was rough on her for most of those 13 thousand miles.

I dont however wanna get assfucked by a dealer fixing it...I've never done a clutch in a car let alone a bike so I'd have no idea where to begin.

I have the clymer or haynes manual for every bike Ive owned, not 100% but it will get me to what I need

WAY easier in a bike than a Car.

As for Chain Maintenance, I can be pretty bad at it sometimes. When I'm taking care of a chain I've put on I try to keep it clean once in a while but then I spray on a bit of Chain Wax which defeats the purpose of cleaning it. By the end of the day the Chain Wax turns black from all the dirt sticking to it. I really dont think it's doing much for the life of the Chain. I might go the route of a few people I've met who do nothing but keep the chain clean. No real lubing to speak of.
Well you can't say "Everytime" anymore :lol:

I've lost a chain (Maybe I should say "Almost lost"? You decide.)

A. I already admitted my chain maintenance can be weak...My sprockets were fine though.

B. The Chain was properly installed...With a Clip Link. (It was on a 600 Bandit. I still have nothing against this method in some applications.)

C. The Chain was showing wear and getting stiff near the Master Link.

Now, first of all, this was all my fault. When I bought the chain I was in a hurry to get it on because I had a weekend ride planned. When it came in they sent the wrong master link. The dealership I ordered it from managed to dig up pieces of 2 other master links. Both the same Manufacturer as the chain but one side plate was from another model of chain. I checked them over and decided it would work. I put it together and it did. It worked so well I never bothered to replace it, just kept an eye on it. This lasted for tens of thousands of KMs. Then I noticed the Master link starting to get stiff. At that point I started looking for a deal on a new chain. One weekend though I was out for a ride and noticed a vibration. I pulled over and found half the Clip broken off. (Like it had been hit with something?) We were about 1.5 hours from home but luckily near a Suzuki dealer and they gave me a Clip free of charge. I put it on and headed for home, stopping often to check it. We were about 20 minutes from home and it still looked fine so we decided to head straight home since my friend was feeling sick. I pulled in my driveway and looked at the chain only to find no clip at all. I poked it with my finger a couple of times and the chain fell off. Close call.

Wow that was long winded.

Actually I lube it at least twice a day out at the track. I use non-o ring chains and there is no perma-lube. If I don't lube the chain, the heat causes bad stretching and sharks my rear sprockets something bad. I have a thread in the dirt forum about my last sprocket and out 49 teeth it was supposed to have, ended up with only 13.

I recommend lube but I also recommend a "grunge" brush specifically for chains and religious cleaning of them as well.

Well I recommend putting the bike on a rear stand, drop it in 1st, and use a rag to clean any dirt off.

Cool! An honest person! :lol:

I won't name any names but there's a guy that keeps posting pics of a jacked up rusty looking chain that supposedly broke when it was perfectly cared for, maintained and was well with in spec for stretching...:wink:

And who would that be?

Hmmmm.... I wonder?.....:lol:

No really, who is it?

*cough*

That's not bad rust at all

Aw opinions, everyone has them...:idk::wink:

Just like assholes?

This option works really well at somin...

Cleaning under your finger nails?

Nope but you're close

Is he "ferreting" out the answer?:lol:

Ding ding ding

Hey! I never said any of that! The rear sprocket is the original which still looks fine and the front is under 10K. I'm not sure how many miles were on the chain but, it was rusted and I think it was a master-link style that was on the bike when I got it which the replacement chain is also a master-link.
As for maintenance, I learned years ago from factory work that lube in dusty environments turns the lube into grinding compound! I just clean it with wd-40 every now and then with a plastic brush. It's a KLR650 so, it's not that rough on chains like my turbo was!
