Thanks Matt for the ST200 throttle bore picture. So the throttle bore DOES taper down. Bad news for me. It looks like it will be more trouble to duplicate an ST200 LIM starting with a stock 95 casting than I thought. Straight bore is easy; a more complex shape is not worth the trouble. Wish Iā??d had an ST200 LIM to study before I made all that noise earlier! Maybe Iā??ll just clean my 95 LIM up with an ST200 UIM port match and optimize the plate screws (still a lot of work). What do you think Alex?
