I wouldn't worry about that. These are not "light switch" motors. They are very controllable while still being strong. Fine tuning with header/pipe and clutch settings is easy enough.
The TT clutch is no different from any 3 shoe clutch. Depending on the track you pick your shoes, springs and bell size.
