I did some more looking around (btw radical duc produces some amazing machines!). I still dont see how SBK or SS tank would mate with a Monster frame. I havnt lookt at those aftermkt pcs yet tho. But I have lookt a little more carefully at the ST2 with an objective eye. I am curious how the ST2 tank would look on the Monster. Can it be done in such a way as to retain the existing seat and cowl?
Carbeuretted Monsters have the electric fuel sender- keep that in mind. I don't know how that would work with the Monster.
