Paid a guy to assemble this motor, put 2 new forks and 4 gears into the transmission, all on the same shaft. Lever moves up and down fine, but only first works. Pull up, nothing, neutral only. Checked to be sure the lever wasn't hitting the chain or anything, all good. Fired up second kick, half as many gears work. No bueno. Guy said he'd fix it for free, but he's 2000 miles away, and I'm not heading that way. Any Zook experts take a guess at this? I'm only familiar with what Honda uses for a mechanism under the clutch, the ratchet and pawl system. No clue on this.
