    I recently purchased a 1972 250WR and am in the process of going through it to replace seals, bearings ect. so I will know what I have got. This bike originally utilized "port" induction but a previous owner installed a "GEM" reed induction system. Upon removing the intake manifold to install new gaskets I discovered that it has a brand new piston installed. The problem is that the new piston does not have the windows normally installed for reed induction machined in it. Does anyone have the dimensions I need to machine these?
