Thanks, I tried that - the microswitch was active not at the half way, I could hear it by touching the lever slightly. I adjusted it, but the problem was still there. Since the side stand was a bit loose, I took it to be fixed, and to set the sensor tight to it's place (it was loose). Again, the problem is still there. The amazing thing is that it happens only at the beginning of the ride. For example, few days ago it happened once a few miles after I started riding, in 6 gear while I closed the throttle down a hill, I started it again (without turning the key off), and then I rode for about 150 miles straight with no problem at all! Yesterday I tried again to create the problem while standing, it happened once after I reached 5000 RPM. It didn't happen on low revs. Any ideas? can it be a defective side stand sensor?
