Could you offer more on #1 and #3...There are at least three clutch mods you can do! All will dramatically improve a polished launch on a basically stock Busa.
1. Convert to cable
2. beef up the hub several places do this,(Falicon cranks for a better basket) and/or add (BDE clutch kit).
3. 2 step mod./ Line lock mod.
I heard that "Bug"Stunnah, to run with the big boys you must fix the weakest link and in this case the clutch is the weakest link. Goodbye stock clutch! This is a pretty cheap mod when compared to the results you'll get.
