slide the fork tubes up in the triple tree. The rear shock has a height adjustment as well.
If you look below the swing arm on the shock assembly itself, there is a black round rubber nut looking gizmo. loosen the hex nut below it and make the threads between the hex nut and the rubber nut disappear.( not too good with mechanical terms.)
Finally, yes you can take some of the height out of it by relieving some preload. I had "experts" tell me that would only make for a softer ride, but I lowered mine so much I didn't have enough adjustment in my headlight and had to make some extensions to get the headlight to point downward enough. As time goes on, I am reintroducing more preload and I am almost back to factory setting. I guess my fat arse is slowly killing the spring. I am sure there are a host of youtube clips on the subject.
hope this help. I know you will love it. if not, they sell like snowballs on a hot day. don't know your year but with those low miles (kms??) that looks like at least a $3800 bike if it is an "08
