I'd like to offer a suggestion for Supersport rule 2.10; Transmission and Clutch modifications Allowed: Sub-heading 2.10B reads "Transmission gears may be shimmed only for the purpose of proper engagement . . ." I'd like to see that changed to "Transmission gears may be shimmed or under-cut only for the purpose of proper engagement . . ."

There are a number of entry-level bikes that suffer from poor gear dog engagement with stock transmissions; the Ninja 300/400 is one, the Kawasaki EX 500 was another back in the day. Under-cutting the transmission is the cure. It's not really a performance advantage except that if your bike doesn't jump out of gear entering corners and your competitor's does, well then you have an advantage, yes. But really, it's a safety thing, and it would be nice if any rider suffering that mechanical problem could legally get it fixed. For riders who aren't having the problem, it's no disadvantage that other riders might have under-cut transmissions. As soon as a rider IS having that problem though, it becomes a safety issue for everyone.
