I'm at 800 ft. Morley kit, full exhaust 152.5 mains stage 7 on 3.5 clip. I still get occasional pop back through carbs at 3000 rpm and it's hot out. A/F 2.5 to 4.5 turns out. it's so close.....but I think I'm going to be lean as soon as temp drops. I may have to go to 155s and drop a clip on the needles. Every bike is bit different.....you may be ok with 155s!
