i have clip ons on my bike, i used the 01 cbr1100 and they work great, but i just changed them, you dont have to change to forks just lower the front end a little, i paid about 60 for the ones i just got, search on ebay for 43mm clip ons and when you get them you have to flip them around cuz they come with a 10deg down angle so turn em where the angle is up, and i think woodcraft makes some that are adjustable and will go under the top clamp,but as for most of them you wont be able to use the steering lock anymore. ill try to get a pic up of mine tomorow.
