I have joined the all mighty motorcycle race. I bought a ninja 250. Any tips for a very much beginner?

I've always wanted a motorcycle. And started saving a while back. Just got a 2006 ninja 250 today. Started practicing. (Stalled 7 times in 1 hour) after the stay at home order is lifted I plan to get my license. I want to thank Ryan F9, dandanthefireman and a bunch of you guys who really got me into this. If you have any tips for me, please speak up. I'm open to anything. via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/funv78/i_have_joined_the_all_mighty_motorcycle_race_i/?utm_source=ifttt
