Ok i got a 95 ex motor from this guy for $100 but it is in peices.It has new rings and the block is honed it just has to be put together. It does not have new bearings and I wanted to know how I would go about finding out which pitons/rods go in which cylinder. Or if it even matters. Also how much would it be for a machine shop to do it?? But I would rather do it myself so any help is appreciated

 

If the pistons are not marked then you can't tell where they go. It shouldn't matter much since the block has been honed.
