i just have a question on how to keep my chain tight on my polaris. it is so compfortable to jump but it just seems that it can't handle it, is there anything i can do???? sorry, what it does, after a big jump, the chain will loosen and eventually fall off if i keep riding it like that, i thighten it up, then i go ride and it does the same thing, its only when im on it hard that this happens.

 

If you are going to be jumping and abusing your trailboss get the HPD chain tensionor .
It will keep your chain adjusted and help to not snap the chain and blow a tranny case

 

Might want to take a look at the chain and see what kind of shape it's in. I'd bet if it's the original you're missing a few orings and it's stretched. Might as well change the sprockets too.

These aren't really made for jumping, but that didn't keep my nephews form putting mine 5 feet in the air.
