Gearbox Input Seal

[SinkyB]

Guys,
I've been running my 1200GSA for a while now with a leaky gearbox input seal.
Looks like a fairly simple if time consuming job.
Has anyone tackled changing one of these themselves? Any hints or tips?
I was wondering if it was possible to shoehorn the gearbox out I the bike without disconnecting the rear subframe?

It's not possible to do without separating the bike.
