94 v max 4 drive chain lifespan question

Hi Guys
Years ago I bought my 94 v max 4. it had 6000 km & the chain had one broken link. I went ahead & replaced it with a new Yamaha chain 94880-08068
Now my machine has near 13000 km on it. I am a trail rider & don't rip on it too hard but occasionally do wind it out. note the machine is virtually stock. I adjust chain yearly as part of my mait program. Adjust meaning ( removing any slack if there is any)
I kinda thought now would be a good time to replace it. But just went to Partzilla only to find that is no longer available. Now what do we do?. Is there good aftermarket chains? & would would the expected life span be?

Thanks
Kevin

surprised to hear your old one has a broken link!
that said if runing quality oil, it seems it should be god to go for a while!

Assuming you have been using a quality chaincase oil and correct chain tension, the chain will last a lot longer than 10000 trail kilometers (a sled that has been frequently dragraced is a different story). The chain itself will for sure outlast the drive shaft bearings.

I appreciate your comments. Hopefully I can get a few more seasons.
Thanks guys.

What kind of oil are you using, Kevin? It has to be that, or you were just unlucky I suppose. It can happen.

Im looking at changing the oil. I check it every season & its clean like new but its been a few years since I have changed it. So I cant remember what is in it. THe manual says 10 w 40 but unsure. I was thinking synthetic gear oil sae 30??? any advice.?
Thanks
Kevin
