2017 RMZ450 problems

I have a 2017 RMZ450, It ran a couple years ago but now will not start. It has a new jug and piston, great compression, but no spark. If I kick it over it has no spark but if I pull the plug and crank the engine with a drill it will spark after the first few revolutions, albiet a so-so spark. I had surgery over the summer and am not 100% yet so repeatedly kicking at it in hopes of it firing are not realistic. Many of the tests in the manual require the engine to be running in the first place. Rather than to continue throwing money at it, can someone point me at the usual problem and how to eliminate them. What's the trick shops use as opposed to having someone kick at the starter? Any help will be apprecited.
