The manual calls for 0.04mm on the intake and exhaust, all my feller gauges have no such thing. they have .004 but thats inchs, and all the mm are more like .152 .203 .508 and so on, do i need to buy a new set off feller gauges or am i just reading them wrong. Its just turned 2k km, so thats the first check figured might as well. Thanks
