C rod2000: you can definetly run without the clutch mod, granted it is much smoother and more predictable with it, I used to do low 1.7 60's on a stock height,stock length,stock geared busa w/pipe and airbox. Launching at 3-3.5K, just let the clutch out quickly and nail it. Yes there are much harder launches out there but this is easy to do with a stock bike. 1.8 60's no problemo, 10.0's stock bike, no problemo if your average weight!! Have fun, becareful
PS. just for fun, try 42 tooth rear sprocket, like power wheelies?
