BentValve,
Yanking the motor is gravy. I just re-bought my 02 GSXR1K from the guy I sold it to, he paid the wrong person to put an intake cam on the exhaust side and it hurt the motor. I yanked it and it's almost ready to go back in.
Everything is smaller & lighter on the 1000. My parts pile wasn't much either. I could lift the motor up off my garage floor and lay it on my work bench. I tried that with a Busa motor once - forget it.
I met a guy at the last MIR race in MD who had a 021K, he races it a lot and I asked him about it. My concerns were the same as yours - would I hurt this thing? I've dragraced my Busa almost constantly for the last 12 months, and between changing the oil and cleaning the clutch, I've never hurt it.
He performs the same 'after-race' routine and hasn't hurt the 1K either.
Good luck and hope this helps.
