Cracked Engine case / mount

Well, looks like it's my time for the cracked engine case experience...



Not sure how long it's been like this, just noticed it when I had the bike stripped down for valve check. I didn't know this was a known issue so I hadn't been scrutinizing my mount locations. I just happened to be shining a flashlight around and saw the crack

Looks like it's time to pull the motor and haul it to a welder. I'll also do some upgraded engine bolts while I'm at it like this thread: https://www.ducati.ms/forums/40-sport...g-yours-2.html

I'm supposed to be heading out next weekend for a 1000 mile moto camping tour of some twisties. There's no way I can pull the motor, get it welded, and then back in and running by then. Do you think I'm flirting with disaster by riding it another 1k miles before getting this fixed up?

I hate that for you VA. Personally, I wouldn't ride it like that since the motor is a stress member. IF your trip is with a group, I'd look into getting a rental.

Good luck,

Bummer. I would not even think of riding it like that.

It's not going to get better by riding it that way.

It is repairable as is. Let it get worse (especially if a chunk or two disappears), and it gets a lot more complex and expensive to repair.

Thank your lucky stars that you found it at this point, and fix it now.

That's no good! I don't remember anyone reporting a broken front mount. All the topics I've read have been the rear mounts. Did the bolt break too?

I didn't think about the complexity of the repair if that broken chunk disappeared. That's it, time to shelve it until I can pull the motor and get it to a welder.

This is pushing me to pick up my brother's KLR for a backup bike. Gotta hit him up for the family discount

You know what, I didn't check that bolt when I put the fairing back on... I'm going to get replacement bolts either way. Not going to do all that work and use the same bolts.

A missing chunk doesn't make it more difficult to repair, really. Just saying. That said, I'd find another mount for your ride.

Thats similar to what mine looked like on my rear mount that cracked. I had caught mine early, so their was only one hairline crack. My rear bolt actually broke. After considering the pros and cons of drilling out the hole diameter in the case, I decided to drill to 12 mm, like the newer ST4's, after welding. So far, its been a good decision, as I have had no issues after the welding and drilling.

What year did they switch to the 12mm? Mine is a 2002.
