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.

I have one of these, I Drag Race it. In stock Class.

How do you ride --- Trails

Need to know more about the springs

erlandson yellow primary spring ?

Beginning Pressure ? 140-150-160 ?

Ending Pressure 290 310 320 ?

40-48 in a P85 secondary is a rather odd Helix.

Usually the numbers are the other way

Like an R8 50 -34


What Type / Length Track ?

What are your Gears

Here is my XC

I do pretty well.

Out West we only race about 450 feet.

She runs about 65 mph in 450 feet.
Very quick the first 100 feet.

Will run with most all 600 / 700 stock and improved.

Still tuning it --
