Very stupid idea!!!
Fisrt off, if YOU don't know how to do it, DON'T. This is not easy.
In order to do this, the forks must be completely rebuilt using new extended length tubes. If all you do is install extended tubes, it will raise the front end of the bike up, changing the frame geometry and cause major handling problems and practically nrideable. The proper way to do it is to rake the frame neck. Basically, the frame neck is cut from the bottom side and reangled, pulling the bottom forward and the top rearward, then welded into place. This is very hard to do because not only does the rake angle get changed, the TRAIL changes also. Trail is the distance from the contact patch of the front tire to where the centerline of the axle hits the ground. Too much or too little trail will severly affect handling and stablility. Trail is corrected due to rake changes by the angle of the triple clamps.
Your bike is simply not worth investing a couple thousand dollars into doing this, let alone risking your life by cutting and modifying your frame.
