If you nose around the web bill and do a search on a few sites...you will find a procedure with some pics.
Its not a tough job but there are a few good tricks to make it more painless.
1.You have to remove the stuff off of the RHS cover of the airbox which is held on with Philips screws..remove the fuse box and master cylinder fasteners and string up.
2. Best tip is remove the seat and remove the 4 bolts up top that secure the box to the bike
3. Remove as many of the philips screws as you can with a long screwdriver from the RH cover.
4. The two rear screws will be impossible to remove with a screwdriver.
5. You can either try to remove these with needle nose vise grips from a ninety degree angle from behind the frame rail (tedious)...or....remove the throttle body bellows clamps and then push the box back with rubbers in place far enough with the four bolts removed up top to access the rearward screws behind the frame rail with a philips screw driver.
6. Helps to remove the sprocket cover as well to slide the RH cover off once all screws are removed.
7. Once the cover is off, the restrictor pulls right out.
8. When you replace the two screws behind the frame rail...replace them with hex head screws so you can use a small closed end wrench...8mm I believe....on them and that way you won't have to loosen and slide the airbox rearward if you take off the cover again...say to put a hole in it.
Thats the gist of it Bill. Post if you get stuck. A camera is your friend for posting here with any questions and keeping track of your steps. You will be fine.
Good Luck.
