Bandi, 15/27 is a fair starting point. IMI and GJ, 17/26., maybe a 27 rear in GJ. The Track, who knows? Jetting, have a selection from 155 to 176. Most of the time you will be around 160 to 168. Needle, stick it in #2 and fa’gatta’bout it.
If you want to be safe, run a 168, a little fat but it won’t hurt it. Just drive the crap out of it. Change the trany oil once and a while. At the end of the year, send it for freshing.
