Not to be a Debbie Downer but I also tried this on my old '14 Sherco 3.0 ST. I couldn't feel a difference between 4 springs and 6. So, I put the other two back in. YMMV. I got better feel out of adding a flywheel weight (which may be a totally different subject) and my clutch used to freeze-up some even if the bike sat for just a week or so.
