when is too much timing a problem

[Pyrox]

like the title says .... how much can you run .. or better yet how much should you expect with 750ccs reason i ask is because with the 750cc and return line you have to have the pressure pretty low at idle and you have to pull alot of fuel with your piggyback... and when you pull fuel you increase timing.... so i guess how much is too much
