It could be many things... engine, tranny, chassis...
My guess is that in first and second gear you are accelerating the hardest, so compression is my suspicion. Head gasket or exhaust. They can both make similar funny noises...
If by "popping noise" you mean backfire, it could be crossed ignition wires, or some sort of misfire.
Engine mounts could be loose or worn.
could be a contant velocity joint
Most likely a CV joint...could be dangerous... consult a mechanic asap
Could be your exhaust system specically your converter.
The gas making the popping noise is hydrogen.
To change gears on a bike, you use the gear shifters located on the handlebars. Pushing the shifter in one direction makes the gears harder to pedal, while pushing it in the other direction makes them easier. Adjusting the gears helps you ride more efficiently on different terrains.
bad plug or bad gas or timing could be off carb needs to be cleaned and or adjusted check timing last but it could also be your starter solenoid if the connections are slightly loose, on my predator had same problem constant popping, just be sure to check the solenoid first
Internal steam via a microwave or heated pan.
Rice Krispies IHTH :)

IT sounds like the Voyager could be losing power to the ignition circuits. Check the crank position sensor first. Make sure that the wiring connections are not loose or corroded.
