Killer project. Ill be watching closely.
I would like to try the same kind of swap on my lil 2008 250 Ninja. I am currently looking for a 2 stoke YZ 400 motor just to have laying around when I toast the 250 twin.
Ill keep mine a track bike so no need for those pesky lights or a battery.
Imagine a 400cc 2 stroke 2008 ninja trackbike.
It would be a blast if i can strengthen the frame enough to handle the extra HP.
