i have an 05 wr450 with a powerbomb header and powercore 4 silence and considering installing a fmf quiet core insert. (way too loud)
has anyone done this?
is it a lot quieter or just a gimik?
did it affect power delivery?
did jets need to be adjusted? what do you tweak i.e needle or just fuel screw?
any other coments on this insert appreciated?
