1997 Third Won’t Start

I have a 1997 tbird 900 in great shape, 19k miles. I’m having starting issues. I’ve replaced the battery, and when I engage the key and the lights come one, I’m getting sound only when I engage the start. But no engine sound, just a small revving up sound from something. Bike will not turn over or act like it’s going to even start. But the click I hear about is happening but there’s also that revving sound as well at the same time. Any suggestions?
