If you notice when you marshal at Indy, about 30% of the time during a race various cars are doing that on the big triple. I was standing at the corner before the runup for that, so I had a good view of it for the whole main... Nothing to be concerned with if your clutch mesh is good... now, sparks like that CAN be when you break a clutchbell or spur gear (it looks the same... worried the heck out of me the first few times mine did it at the Texas State Series race... but it was fine.)
