Hi. I have 2012 Honda cbr250r purchased 3 years ago ( 3400 miles ) and have performed all the maintenance on my own during this period (thanks to this forum and you tube). It now has 7,000 miles. The bike had no issue until last week when I was trying to prepare it for the year (habit of checking and changing all fluids such as brake fluid, oil, clean up and adjust chain etc. in the beginning of spring every year), it just won't start. First it looks like it is going to start but in the second or third try, having a trrrrrrrrrrrrrrr sound coming under the seat. When i opened the seat, it is specifically coming from the bottom right side of the starter switch assembly. I pulled out the fuse and it is fine. Also checked other fuses and don't see any issues. Any suggestion whether I need to replace the switch or should I look for something else.
