So, if your not getting any vibrations after a tko install with a mcleod scatter shield, its safe to say that its indexed fine as is? I have absolutely no vibrations, but what I do have is a howling noise. For example when it does it- say i take it to 2500rpm in 2nd and keep it in gear and let the rpm's come down on decel, it'll howl or in 5th on the hwy passing someone and giving it more gas, it howls. It does NOT do it in 4th. Any idea's? Im wondering if the scattershield transmits more noise? I gotta check the fluid level also.
