I am not SWB; +9.5, so when the bottom yellow lights I smack WOT and throw the clutch as far away from me as I can. You don't have that option, so I suggest you launch a Gen I between 3000 - 4000 rpm. Gen II...best rpm I have found for launching is 6500.
Roll up and light the pre stage light. Then get as far forward as you can on the bike. Once you feel comfortable, find your clutch friction zone. (the point where you just barely start to grab/move) then bring your rpms up to 3k and use your feet to move the bike forward and light the bottom light. When the bottom yellow comes on (don't wait any longer) yank down to WOT and let out SLOWLY on your clutch lever. The more practice you get, the faster you can throw the clutch away. BTW, if you don't have a clutch mod, and you plan on drag racing, it is well worth the money. The OEM back torque limiter can't handle hard launches and will eventually do damage to your stock clutch!
Hope that helps....you're on a busa...go get that yamadog
