Black Red Secondary spring

[ecut]

I have been running stock helix set up with the Black purple spring but dont like how it waits during intermediate throttle to upshift.

anyone tried the black red secondary spring?

How is your backshift? How do RPMs hold when on a big climb? I've been using the new Gold/Black with good results.

Backshift is fine it the lack of upshift at mid range rpm i don't like
