250r guesseting

[Troy86250r]

Im about to tear my quad apart for a ground up rebiuld. I have decided it would be a good idea to guesset my frame. So heres my question, where are the weak pionts on the 250r frame? If someone could post some pictures of guessets they have done in the past that would be great, also maybe some dimentions would be nice too.
Thanks
