Cool. didn't have the whole story - coming late to the scooter scene...
After the partnership ended, due to the terms of the arrangement they were able to keep producing scooters. At that point they started making the reed cases... the first significant upgrade to the design since they moved away from piston porting.
I had the sense that "LML" cases were preferred by tuners.
Turns out I was half right ^.
So if you are going with "small block" cases as some like to call 'em - then LML reed cases have some upside.
The ones I have are rotary - ground out for reed.
Perhaps those wont be the base to utilize...
