I'm just wondering if anyone knows why yamaha does not want to build a 440 racer. With all the technology they have at there disposal I bet they could build a real winner. Do you think they might have a 600 4 stroke that they will be allowed to race in the 440 class. If they came out with something like that I may have to jump ship to Yammy. If anyone has any info on such a sled I would love to here about it. There must be someone here with some inside knowledge from yamaha.
