From my reading and understanding of doing a bore increase, the rule of thumb is stated as a minimum 0.003-0.0035"(0.0762-0.0889mm) over the size of the piston, for any bore sizes between 2.500"-3.625"(63.5-92.075mm). The 81 GS450 manual says it's 71mm piston/bore size, but doesn't give me exact for either/or.
So if I get 73.5mm aftermarket Suzuki replacement pistons, that would put my total recommended bore size at a minimum of 73.5762mm. I figured I would round it to maybe 73.580-73.6mm on the bore size, as it's a little under the midway point between the recommended minimum of 0.003"(0.0762mm) and max of 0.005"(0.127mm), to leave room for "error". Does that sound about right?
I just want to be sure I am calculating this correctly.
Any input would be appreciated!
