Does anybody really know how much input Yamaha had in the developement of the F-4 chassis?? Keep in mind...they have been testing the nytro motor in a cat chassis since 2009...just saying...that motor fits pretty well in there.
that motor caused a huge change in the pyramidal frame as the tubing needed to be bent around thw 1050 mill. I am not saying it doesn't work but if you are saying they were working on this chassis with the 1050 install in mind for 3 years they did about the same engineering some home builder might attempt.
