Bro, a couple of frens of mine told me that u have to skimm a little abit at the surface of the pully as to plug it to the shaft.. This is due to the pully surface touching the shaft connecting area surface.. why this thing happen? izzit this cam pulley are design to pnp kind of rather we have to mod it a liitle bit..
I just installed an evo 3 spring + absorber (front and back) but the half cut shop gave me a wrong combination. The front is now around 6 1/2 fingers height and the back is only 2 fingers. Would there be any problems...
