That's a tough one. I've never broke a chain on any of my sleds, though I've broken teeth on gears. I don't think I've heard of anyone breaking a chain before. There must be something going on there that you're not seeing. Do you have a reverse kit in there? Is it possible that your gears aren't lined up proprely?

Something is defintely not right. I have over 7000 miles on mine. I know of others with over 10 and 15,000 miles on one chain on same sled. Are you setting the tension correctly? Screw in tensioner by hand till there is resistance, then lock the locknut. Was the chaincase apart for some reason. Maybe it didn't get reassembled correctly with all the shims in the correct places. I've also been told, if either a chain or gears break, replace all of them. They need to seat into eachother. Maybe your new chains are being broken by old gears, or something.
Sure others will have ideas too.

No chain issues here either in spite of huge miles on em..........best pay close attention to your gear alignment and chain tension when putting it back together cause it's not a common (or one I've ever heard of) ZR kinda issue.

How do you stop when the chain breaks?

Definately something wrong in there. Maybe missing a spacer washer or got them swapped around accidentally. Did you ever remove these gears to change out a track to cause this to happen? Or has it been this way since new?

It has been this way since i got it. I will have to look real close and put a straight edge in to make sure this does not happen anymore. It is not fun when the chain breakes. No reverse on the sled.

Also tighten adjustter till finger tight , then back it off just a little.

tHAT could be it. Maybe you have sligthly too low of tension. The resulting impact on the chain from a bit too much slack will eventually tear it in two.

Or, maybe your gears are not in the same plane so your chain is forced to twist a bit.

$0 I built exactly the sled I wanted to!!

Are you running the wider chain ?? They make a heavy duty chain that is around 4 rows wider but requires a wider top sprocket as well . If you are running an agressive track or stud pattern this is a must haveor the stock chain will not hold up. w00t SWRules

I just broke my second chain on my 900 m/c. :bash: Just returned from the dealer to get the clutches checked out, ended up loose set screws, 2 1/2 hours away and went 2-3 miles and it broke. I have 575 miles on it and it broke once before a couple hundred miles ago. I have been keeping it tight, and it has a 50 chain, so back to the dealer tomorrow and hopefully get this cured. I think i am now seeing a major bonus to diamond drive system.

There were people on here last year complaining they were averaging 1000 miles on the 2004 zr900 before the diamond drive would break.
