I went out for a ride in the area today on my '75 R75/6. After about 45 miles I made a quick stop (2-3) minutes and went to start the bike up in first gear and nothing happened. All the instrument lights were on, but the bike would not turn. After trying this a few times, I put the bike in Nuetral and it came alive on the first attempt. About a half an hour later of riding, my curiousity had gotten the best of me. I pulled over on the side of the road, turned the bike off and tried starting it up again in 1st gear to have nothing happen. Put it in Nuetral and no problem starting up. I experimented with this a few more times once I got home and am having the same results. Anyone have any idea of what's going on? Thanks for the feedback in advance.
