When you buy a drag frame they are mostly all the same, except for motor and plastic body mounts, they usually run a small light weight radiator not from a 250r or a banshee.
But you really should Tig weld everything and if this is a problem then just wait until you see a frame setup for a Honda, they are out there but they maybe a little pricer than a frame setup for a banshee just because there are so many.
