I have heard others have lowered their rear ends with not too much trouble but personally the way I see it, if you do lower it will have to mean stiffer springs to compensate otherwise you will bottom out that way,
Also, If the stiffer springs doesn't bother you having a harsher ride, then I would think that riding with a lower bike would have to increase your chances of scraping just because of where our pipes are on our bikes and how easy it is to scrape if you haven't dialed in the right pre-load.
Believe me I know.
I'm happy for anyone to tell me I'm incorrect here cos you do need to have all the facts before heading in that direction.
Good luck
