Another Silly Chain Adjustment Question

Not uncommon with this type of chain adjusting setup on any bike if the bolts aren't properly greased. Remove the rear wheel and remove the chain adjusting bolts completely from the swingarm. Coat them in some decent waterproof grease, I use some saltwater marine spec stuff, then screw them all the way in and out a couple of times so the treads are well lubed up. This is one of the first jobs I do on new bikes. Not sure if the warranty would cover this as it's basically poor/lack of maintenance.

 

It must have had very light use if the chain didn't need adjustment in that timescale. This is another area on a bike where manufacturers seem very economical with the grease on the production line. I would expect the dealer to have at least checked the adjusters did actually work!
A friend of mine had this problem with a dirt bike he bought second hand a while back. The adjusting bolt on one side was seized so bad it needed heat to free it up. What you DON'T want is the nightmare scenario of the bolt snapping in the swingarm which I've seen done before.

 

You did undo the lock nut first on the adjuster bolt didn't you.

 

You can buy a freeze spray for about £6 ish fae screwfix,it got 2bokts fae my crash bobbins off my old hornet when nowt else worked,and 4 old seized wishbone bolts that were rocksolid frozen even massive extension bar wouldn't move them

 

Great asset to have in garage it's got me out of few tough spots where only other options involved a grinder
