I am in the process of putting SLP pipes on my 98 600 twin. Going to run 10-60 primary weights, erlandson yellow primary spring, currently just have a stock helix but i plan to get a 40-48. What is stock on these? I have a bunch of old erlandson secondary springs around from back in our XLT days. some are even brand new. I have a yellow and an orange laying on the shelf here. What am i best off to run? Or should i just buck up and buy a new spring. Don't want to buy if i have something i can use sitting here.
