Congrats on your GRiSO. Hope it brings you many miles of smiles.
While this isn't your first rodeo, and I apologize for sounding patronizing ... but I'll go on anyway.
I'd recommend going slow on mods. My garage is littered with 10% of the things I thought essential for my Guzzis, and I've given away or sold three times that stuff that's still here.
That said, I have a tarted-up GRiSO; most of us do.
You obviously know what you are doing WRT suspension and front forks. But today -- yes, today, after four years and 16K miles -- I finally realized on a two-day 400-miler in south central Pennsylvania that I have been wrong about the GRiSO's handling.
All that time, I have viewed the GRiSO as a bit of pig, at least compared to my Norge. The latter was (and remains), IMO, a spritely lass for a big fat girl ST. I love the way it virtually falls into turns.
The GRiSO, OTOH, with its long wheel base and other attributes, requires forceful countersteer to enter and leave turns.
I thought that was "bad," and have whined about that here and elsewhere when -- finally! -- I realized it was just different. I began to appreciate and enjoy that today.
OK, yes, I am a slow learner.
Now, I may yet fiddle with dropping the TT just for the heck of it, but now that I see it was me, not the GRiSO, I may "just ride it."
What a(n irascible) sweetheart the GRiSO is. Have fun out there.
