well rule of thumb is 10% on both jets for a 70 bbk
if you are talking about running an open air filter i would put another 5% up
Howerver i strongly suggest to run it with an air box on as an open airfilter wont increase performance on a bike unless it is highly tuned and can bring about many problems

Well if your not going to put on a new air box then go with a uni and make sure you oil it up NOT TO MUCH oil NOT SOAKED.
And then try a #88, #90 and #92 Main jet. Leave the PILOT JET alone that you will Find out if you need a bigger one after the Air Filter is on.
