Funny (painful) story on the last option:
A few years ago, I got a B25 running for a 40 something, just divorced, in a mid-life crisis guy who had just bought his first motorcycle - an absolutely original 1969 BSA B25. He was having a hard time starting it. I showed him that need not jump on the kick starter like it was some hard to start monster by hand starting it - didn't sink in. I had promised to teach him how to ride (tells you how hard it is to get a motorcycle license - he had one). Again, he jumped on the starter and broke the ratchet.
I said I would fix it, but let's get you taught. So, I push started him. Of course, he stalled it over and over, and big old me walking to him every time to push him again. BTW, I was 67. Finally, we are part way up a small hill so I was trying to explain how to bump start it himself - he couldn't get that done. Now I'm pushing down hill and he's starting and stalling. Each time, before pushing him I reminded him to pull the clutch as soon as it started because he needed to learn how to pull away from a stop without stalling. The last time, I was pushing/running hard try to give him enough speed that he couldn't stall before he got the clutch in and he got stopped. When it fired, rather than pulling the clutch and not listening about the throttle, he had it wide open. I'm leaning over, exhausted, running hard, and he jerks the bike out from under me. On the way down, my years of Judo training kicked in and I tried to make the turn to fall without getting hurt but didn't quite make it to my back. I REALLY wish my collar bone had broken - when I got up, my AC joint was destroyed, and the end of my collar bone was at the back of my shoulder.
The medical nonsense that followed is a story for another time. Suffice to say, I spent 8 months without the use of my left arm and 8 more months of PT before I had full motion back, but it was still very weak. Took another year, to get it back to near full strength.
Even if I were still strong enough to push start someone, ain't no way in hell I'm doing that!
