if the gk76a uses 34mm carbs and the sp 35mm carbs, if one fit's 36mm carbs from the 750w get proper a/f ratio and shortened the final gearing wouldn't that work?
btw is the CDI from the SP and normal gk76a interchangle, cause I read somenting about the SP being 1 pinn only....

Thanks in advance

You could do that, you'd need to get/match up the inlets, also too big and you'd get a miss match between the inlet and exhaust. Main prob is not the carbs but the restrictive stock exhaust and the 750's carbs will be too wide and you will have to make up a new rack etc. D'nt know about the cdi, jay may know or Gazz has a SP maybe he will take a look.
