I was changing my front tire and while i was putting it on the zx12 fell off the stand. So it turns on but the starter does not enguage unless i jump the relay. So what could it be? It fell on the right side. F1 demo code 21 and 23????? Now f1 stays on when in the second mode. This has got to be the dumbest thing ever. What a great machine 2000 zx12r.
