The Mordern Bajaj Chetak Rides One
 
The method that works well for getting about the same tension on the shifter cables is to hand tighten the adjuster bolts as much as I can without putting lots of oomph into it. Then I tighten down those lock nuts while trying to not turn the adjuster bolt. The cables are evenly adjusted, which is important so they don't jump out of gear, and there's very little play in the shifter. It goes into each gear pretty smoothly and confidently.
