What frame is it? Does the engine vibrate badly? Is the engine mounted solid to the frame, no rubber or resilient material between it and the frame?
Do you ride it hard? Jumping curbs or rough terrain?
Please take my advice and start looking for a better bike. That one is going to get you hurt.
I did think about welding but like you mentioned its telling me something.
Lately I have been welding frames up, so I think I'll have a go for a motorized bicycle frame.
The broken frame was a murray monterey 70s-80s. I liked the fin dropouts. but these frames have been weak. The frist I used, I had to weld bracing bars from the fatigue it was getting. So its time to move on.
Thanks and safe riding.
