Cam chain tensioner

Does anyone make a manual adjust tensioner for the 13 yz450

I bought an APE tensioner for my old 03 250f, wonder if it would work. Never installed, got it around here somewhere

Why would you want a manual tensioner when the stock one is a proven reliable design? The only time they really fail is due to poor maintenance habits.

I have had it jump time 2 times and this last time it took the head out. Brand new oem tensioner 1.5 hrs into the ride jumped time

Something wrong with your chain if that happened, IMO.

It's getting new chain and cams cause my intake cam looks like it has spun some in the gear.
