Where is the front fork pre-load sag adjustment on a 2013 TXT Pro 280 ?

 

Thanks guys 

Fork with the drilled red ring at the top. The fork cap nut turns. Clockwise for more spring pre-load. It's a bit stiff to turn and will only screw in or out till it reaches its end stop.

There is  a red ring on both forks.  One has a C on it the other a R on it.  It guess C is for compression and R is for rebound.

 

I dont see anything for pre load.  There are red rings on both sides. 

You cannot set the preload, only by putting shims/spacers on top of the springs.

Error on my part, I thought the 2013 fork tops were the same as the '14 + '15 Racing models.
