262 mm minimum lenght according to the book for the 73a, that's the standard one not the sp, sp forks are 16mm shorter than the standard but I don't know the spring lenght, should be in the manual.

Thanks Chris, I measured the springs out of mine at 288mm. I think I will try some ktech Bandit 600 ones which are 295.

Found the answer 73a sp have a spring length of 290mm . I went with Ktech 295 35mm 8.5 springs as an upgrade and I think they work very well. Good for fast road/track work I'm hoping. Had to stick nearly 30mm through the top yoke to get the ride height back to normal.
