Amazing! Very cool. I like it !!!
I FOUND it. Yes, the ones I found appear to be 5 speed. I see the gear position diagram has 1-N-2-3-4-5 in the decal on the stator cover:
I saw "Zongshen" on one red valve cover photo. I wonder if Zonsen is another pirated logo, or just a different Zongshen logo. Could be made by Zongshen.
Heat could be an issue depending on where you are driving and how hot it is out. You would want wings focusing air through that head if you are riding off road (slower speeds, more work!).
