To correctly tune your bike with a O2 sensor you need one of Dyno Jet O2 Optimizers or one of my O2 controller, the resistor O2 eliminators do not work so don't waste your money on them.

Never heard of a counter shaft needing adjusting before best get a mechanic to have a look at it, I bet the primary nut on the crankshaft is loose.

This clip taken from a another forum shows the problem, notice the white mark at the end of the crankshaft and how it stays still while gears move
