GSXR race kart

I saw a video of a Kart w/ GSXR engine bored & stroked to make it 1100CC of asphalt rippin' excitement! I believe you can still see the video @ www.madville.com; look for "gixxer kart" It is insane watchin' that guy rip trough all six gears! He must be going close to 100 mph on the straight aways! How hard would it be to change foot shift to hand shift and hand clutch to foot clutch. I already have a GSX-r 600 engine I want to make a kart out of & I wanted to make it similar to that kart! Any ideas for suspention would alo be helpful.

I tried making a kart once and I never got started it's still in my plans though.
