I'm running the same setup on my e50 other than the stuffed crank (shoulda bought it) mine runs good, does 35 no problem pulls to about 45-47 on flat ground, itll do 35 up decent hills perfectly fine as well. Running a 2.17 atomizer, 82 jet, needle in third from top clip groove, timed at 17° . Nearly keeps up with my buddies 70cc reed cylinder tomos.
