I am looking fro that pregen swap. Has anyone got a link ? BTW, reading this awesome material
https://www.ninjette.org/forums/showthread.php?t=153624 gives me some fine ideas. I was thinking about 250cc 12,500 rpm supermoto since i got one spare. Last time I checked 500 ninja has the same mounting points and KLE500 was an enduro copy ^^ it's overweight though...
