New guy with a project KZ750 Twin

Hi guys.
Just joined up. I have a 750 Twin i just got given because the last guy couldnt solve a problem in the motor and never finished his project, so now i have the challenge.

It has been done in a Cafe racer style so far with only fairly cosmetic modifications but apparently fully rebuilt engine (just it wont go yet)

I have attached a photo and look foward to talking/asking some questions as they arise. Thanks

Luke
