I have a set of PSI LS1511 beehive valves springs (Katech's valve spring of choice) roughly 2000 miles on them and I took them to LME yesterday to have them measured and they were all within 3lbs of spec on the seat pressure and open pressure which is normal on a lightly used spring. Coil bind came in at 1.094 Katech sells them new for $304, I will ship them to you for $[B]Sold!
