I have a spare bottom end which im going to rebuild, it seems in good health, no damage to tops of pistons and i turned it over via a spanner on the bottom pulley, smooth but with abit of friction which im told is ok ! Im just looking into what it will cost to rebuild, has anybody done it recently, and is it worth having the tops of the pistons shaved to lower the compression, lighting and balacing it, has anyone got any advice please.

Id like to run around 200bhp
