Guzziology v 4.7 versus V9

[Hickster]

Hi Folks,

I have a 1998 V11 EV purchased new.  I picked up version 4.7 shortly thereafter.  At the time, it had some info on my bike.  I was thinking of picking up version 9. 

Does anyone know if there is significantly more V11 EV information in version 9 versus version 4.7?

Thanks,

Alex
