primary spring help

[ekimsx600]

I was wondering what primary spring I should install in my primary clutch. I have a 99 sx600 that is pretty much stock. I have installed 8ca weights with .8 in the tip 51\43 helix with the stock spring wound to 70* Any ideas on a primary spring would help me out

You are gonna need a big spring to pull that helix & weight combination. Get a o-p-o part #90501-605J0-00. The 8ab weights would have been a better choice on that sled.

I have a set of 8ab's with 2.4 grams in the inner hole. I can put the ab's in if they are a better choice. Would this use the same primary spring?
