Been having some issues with the way the bike wants to start. Also noticed a crazy harmonic hum/roar when I would pop the gas, so after some digging, my own assumption, think it is valve float. not to mention i just adjusted the valves less then 10 hours ago. So I ordered new KW springs. After pulling the rocker box, I took, tried to turn the springs with my fingers. I could turn them with out much effort. These are the orig springs from 00 in the bike, been running a 3 hot cam for over a year. I think these old springs are just fatigued to death. Sure hope they do the trick. What is the seat pressure supposed to be with stock springs?
