Anyone done a front motor mount drilled through the frame?

Mine's been holding up very good, wondering what everyone else's experience is.

I have about 30 hours on the bike.

Probably should change out the studs, bolts, washers, nuts and plate for higher grade to last longer though.

Double nutted for safety measure.

Frame is steel mix and magnet attracts to it.

Just keep an eye out for spider crack. My friend Jody drilled his bike frame and it broke in two

Scary thought. Maybe a sleave should be added?

I'm not saying yours will.. Maybe Jody just got a bad bike with air bubbles in the metal ??

Sorry, The way ya got that mounted, A hole in the frame and spaced with all those washers I guarantee your frame is gonna start to show stress cracks from engine torque and vibration.
I suggest a Universal mounting bracket, Their made so ya don't have to drill a hole in the frame. In your case so your frame don't crack.
Here are some pictures of mounts that might work for you. There are many universal mounts available, just gotta look

Think of all the weight/stress on that tube and the curve is the weakest point.
