can you swap different /piston sleeves in different motors if the have the same stroke and bore?
my motor has a stroke of 16.80 and a bore and 16.26, could i take a piston/sleeve set from another motor with these numbers?
the reason i ask is because i have a picco .21b(3 port) and its hard finding parts for this motor and i noticed that all of picco's .21 motors have the same bore and stroke.
Maybe maybe not....
Even though the sizes may be the same, the inside of the engine case has ribbing on it that directs fuel to the sleeve ports. So even though the sleeve fits, the ribs may not line up where they should...
