is the stock raptor chain to weak for the power it seems two or three hours after a adjust my chain it is loose agine is there sometihing i am over looking in the adjustment or is the chain just to weak and if it is weak can you suggest a good chain

 

Sounds like your chain adjusters are backing off. I think if the chain was too weak it would snap, I reccomned putting BLUE loctite on the bolt threads.

p.s. I still reccomend upgrading your chain though.

 

Look at the stock spec on the chain adjustment in the owners manual. If adjusted as it says the chain appears to be to loose. But if I adjust it that way, it doesn't change that much. If I adjust it tighter, it loosens quickly.
Just my own observation.

 

The stock chain isnt any good if you ride hard. I have snapped 2 on my raptor. Sidewinder makes a chain that seems to hold up good. It is a little expensive vut will save you from snapping the china back in the trails 20mi and having no way to get back.
