Hi, I own a 1989 Nx250. I bought it in 1995 with 3,000 miles on it. It now has 11,000 on it. It has been a great little bike. Every once in awhile it would just shut off, almost like someone turned the key off. It would always restart. It did it the other day. Now it will not start cold. It turns over and sound like it wants to fire off, but it will not. I suspect something electrical. Any help or advice would be appriciated. Thanks
