If you got rid of those geckos....it would feel like you already had Alky....
bump the timing to 7, drill the main jets and dump tubes out, larger pilots jets and install power jets in the carbs.
You'd be wasting your money converting those carbs to alky....get a new set. 35PWK, 34PJs or 35TM carbs would be fine for that motor....
Is your crank already trued and welded, as well?
And get rid of the airbox and get pod filters.
