oil pump chain life??

[180 nytro]

just had a question, i had my engine apart and i had looked at the oil pump chain and seen that it has a fair bit of slack in it and was wondering if i should worry about it or not, the sled has 2500 kms on it, in know there are lots of guys with alot more than that?

So what is the life of the chain or when should it be changed?

Seems like there should be some sort of tensioner on it,maybe a spring loaded bumper?thats weird
