What main are you on now.
Shouldn't need to go up more than one size with just a pipe change especially with the stock airbox.
May not even need to change it at all depending on the flow of the pipe.

I recently read a topic on carbs from a US Z site. The chap who wrote it seemed to be well known and well respected. From what I remember he said the rule of thumb was: up one size for cone filters and the like, up two sizes for freer flowing aftermarket exhausts. That would put you at 115 with standard airbox.
