Honda piston sit 1mm ie 40 thou below the top of the block. In the days we used them the norm was 10thou of the top of the block, 10thou off the bottom, 10thou off the top of the crankcase and don't worry about the last 10thou!! My trials engine's like that and has been for 10 years. It goes well!! However, nowadays I agree that the sports slipper piston are the way to go and that's what I've used on more recent engines and as well as being excellent, they save a lot of messing about.
