You don't give your weight, so no clue as to if your front springs are too light, pretty common on SVs.
I weigh 200 lbs, and know the spring rate is not enough; I do slide my oversized buttocks far to the rear of the bike while braking hard, something I learned from enduro and observed trials, when braking hard. It takes a bit of practice, stand on the footpegs and hang your rear end over the rear end.
