This is the first Harley I have ever owned. Bought it about 4 years ago. It’s been a great bike but here recently, I have noticed/been hearing a strange noise when I am in forth gear. I have asked a few people and get answer from, your clutch needs to be adjusted too you need a new transmission. Well I’m not a rich person so I was just wondering if someone could point me in the right direction. And just looking for a few pointers. All other gears a smooth. Any ideas?
