Removing the BorexStroke Ratio Cap

Since you guys have developed the car bodies to only hold certain specification engine sizes, why don't you remove the borexStroke ratio cap? I only ask because I would love to build some motorcycle engines to mount into small cars but they usually have a ratio that doesn't fit the game (the Yamaha R1 is 78 x 52.2mm). Since you guys originally placed that cap into the game before you built the car body designing I was wondering if you have thought about removing it or at least giving some more space.
