1000 XP Dual rate spring question

I have a set of the medium weight springs from Racer-Tech on my XP.

My question is…..what’s the length on the rear main spring?

I’d really like to go with a two or four inch longer spring to help with the rear ground clearance (front is perfect), and not lose the extremely comfortable ride.

I could take the springs off and measure but I was kind of hoping someone on here could give me the length without going thru the trouble.

Thx,
Jeremy
