moby motors r'nt supposed to have lowend, you have to make it up in the variator setup, if u read the wiki porting closely (or at least the original article) it says to run 2 balls in a 4 ball variator as well, since we all have 3 ball variators u could run 2 balls in the 3 ball or get a replacement back plate that makes the 2 balls symmetrical.
or a malossi variplus, hella worth it.
my yellow bikes motor setup without the crazy transmission had trouble out accelerating 1 speed puch polinis, it was engineered for higher rpms not torque.
o and mopeds follow no rules.
