I'm a new owner, and a newbie on a bike. I have a '74 CB200T with 2,800 miles. Barn find. Been riding it for the first time recently and made a few mistakes. The biggest one: not checking the oil. So the gears got sticky. Also, the battery seems to need a trickle charge now and again. This morning I added a quart (didn't empty what was in there because the stick showed NO OIL. But then I decided to do something a little MORE cavalier. I took a very fine sandpaper and "cleaned" the point. Whereas when the battery was at all charged enough to jump right up either by electric or kick start, now it turns over but will not start. I think I over did it on the point. What might I do to check to see if messing with the point was the cause of my situation with starting the bike. Thanks in advance!
