Well, preparing for some hate here.
Ordering Jets for the puchs I am putting together. Setups will be an E50 with mesh filter and a boss pipe, and a ZA with a mesh filter and circuit. Both have 12mm bings. I currently have a bunch of 60's even jets leftover from my batavus. I planned on ordering a set of 60's odds, and a couple 56-58's as well. Should I get some 70s to be safe? Or would that be complete overkill?
