suspension?

hey guys has anyone fitted longer springs to the front forks?
my 400 has longer springs in it and i am just wondering what level do i fill the oil to with the springs being longer?, the stock oil level is 125mm no spring, everything compressed, with a 275mm spring.
whats in it is a 320mm spring and 220mm oil level spring out and everything compressed.
that just seems low even with the spring being longer will it really make that much difference with the spring being longer?
cheers Tim

Bump, this confused me Tim, Can you repeat the dimensions clearer please.

Not that I know the answer But I'm sure there's someone on here that will have a lash at it.

Cheers Ponti.

stock the oil level is 125mm fully compressed with no spring. (stock spring is 275mm)
whats in it 220mm fully compressed with no spring (spring is 320mm)

i got i info from some 400cc VFR gurus oil level remains the same (they reccommend more) whether the springs are longer or not
cheers Tim
