Yeah too many details are missing but I guess for a beginner it's somewhere to start.
Most times gas oil mix is best used to try to start your engine instead of starting spray or WD-40 too.
Starting spray will remove any oil from the cylinder walls rings and bearings causing damage.
Also little was said about not having a airbox and filter or correct airbox/filter could result in a not running or poorly running not tuned bike.
I don't like his timing specifications or way of checking timing either
Most of those are specific to the model and what the manual says not just a eyeball guess.
