Get it set up by someone who knows what they are doin, it's worth the small outlay.
Also if you ain't lucky enough to be on an ohlins rear and on the standard shock change it.
The oem shock is dreadful, read the threads!
I personally changed mine for a rsv unit that I amazingly got for £28 on eBay!
Being a 20 stoner myself I found the original shock harsh, the wife hated it on the back, she got off it the first ride with the replacement shock on with a big grin and couldn't believe it was the same bike.....
