Bill you would do well with an ICC. However you need to jump in Jason’s back pocket for the tricks to make SOLO with ICC livable.
I had an ICC Vortex RVS and it is a monster that was built by DDC. When taken to the limit of the SCCA and Homolugation rules it is going to be significant money. And as Jason said Get a whole package Air box to pipe and mount, drive gears. carb jets, needles, atomizers. motor mount. and don’t forget water pump and radiator. I paid 2500 for a turn key RVS which was hot in the day but these are 2004 vintage. and then had to put a top end in it.
