Re: I'm Buying my First Motor
Warning : Removing too much metal can make your engine have more compression, it can also lead to piston knock. Also, make sure no metal shavings are left on both head and jug before reinstalling. For a clean job, you should use a flat surface (most often glass) and glue to it sanding paper (what grit?) and use circular motion on the head and jug surfaces (better than using a file).
