RE: Just got Nouva nitro , need help !
Yup. Furthest out, more like a chopper.
No need to store the bike vertical, you only need it this way when starting, or immediately after running, just to keep the oily stuff out of the cylinder. Once you've finished for the day the best thing to do is empty the tank and / or run the engine till it runs out of fuel, then put around 10 drops of after run oil in the carb and turn the engine over to get it worked in. This helps neutralise any remaining fuel which is hydroscopic and can very quickly turn the inside of the engine into a rust bucket!
Have fun,
