Hi All,

Had a low speed low-side in gravel on Sunday - and as a result I have the following issue I'd like advice on.

My Daytona had R&G Crash Bungs fitted, which bolt onto the top engine mounts and protrude on a stalk through the gap in the fairing. The RH side one (which hit the ground) is about 6" long.

When the bike hit the ground, the forward momentum (only about 15mph) has levered the crash bung back on the stalk about 30 degrees - bending the bolt which held it in place through the engine mount.

This has deformed and cracked the engine mounting point on the frame, leaving an angled surface and an oval bolt hole (see pics).






My question is how you would go about repairing this. Should I get the engine dropped out and have a specialist weld it up and try to build up the aluminium - or would it be sufficient to have a stainless sleeve made up to fit over the end of the mount.

I'm worried about the structural integrity of the mount point - should I be? I assume the engine is a structural part of the frame.

Any thoughts on how you'd approach this would be appreciated.

Cheers,

Chris.

Chris, I'm no structural engineer, but it looks like it can be repaired. Can you tell if the engine's mount casting is okay? Good luck.

Hi Brad -

I'm pretty confident that the engine casting is fine. The cast mount on the frame is on the outside of the mount on the engine, so the frame casting has taken all the pressure.

Cheers.

Did you try clicking on them?

It doesn't look too bad from what you can tell from the pics.
Insurance would probably total it however - any frame damage typically dictates that policy.
If it were mine, I would most likely bore it through and fit an insert bushing.

LOL no..........



I see I see!


Well, I don't know if you made those sliders or if someone else did, but a slider is not every supposed to be nearly that long. If you want the ultimate street protection, street rails are the way to go. I've never checked to see if they are available for Triumph.... but I'm sure with a little know how and a welder a pair could be made.

The block looks fine, but that frame took quite a hit. I would be weary of welding because of the heat as well. You might get away with just bolting down tight on the mount, but if it was my bike I would find bolt the same size, wrap it in 1 layer of seran wrap, get some of that putty steel, stuff it in there with the bolt. After it dries, the seran allows the bolt to work out. Drill with appropriate sized bit, replace stud into head, and call it a day. That particular part of the frame isn't under the most extreme stress, but it helps with the overall load........
