It only goes in one way. So, no. But, without actual rebuild instructions and just going off an exploded diagram, there's something I missed.
So today, I'm going to tear this MF'er apart again and figure it out.
And if I can't, I may swap a Minarelli P6 or P4 into it.
Parts for the JLO engine are nigh impossible to come by, so the engine may get shelved, but this bike will run again, no matter what.
