Thumbs down Dragster RR Crack in Crankcase

Hi team,

I started gaining oil drips after 1 1/2 years of happy Dragster RR ownership - noticed at the third sprag clutch warranty fit. We monitored the oil drip and thought the oil bung, changed the oil bung, and still have the drip. The only MV authorized service centre 450kms away, the other side of New Zealand, checked it out, and found it to be a crack in the crankcase.
To add to this headache, the 3rd Sprag Clutch with software update has seen failed starts starting to occur in the last two weeks. From experience in sprag fails, I predict incoming...

I love this bike and still goes like it did on day one. Still in mint condition, looked after, and never been over.
Oil changes have seen nothing strange or extra foreign bits. Its full noise and not complaining or making any noises. There's definitely nothing foreign in the engine that the service centre wants to take my bike in for to check, even if there was, it would be through other MV warranty work. This seems crazy when they have the test result and took photos? I do realise they need to find out what other parts are needed if internal cause. My scare is not seeing the bike again for months and an advanced bill.

What process would I expect to follow on fixing the crankcase under warranty with MV Agusta? How does this work around the world for MV Agusta?

Any experienced crankcase experts hazard a guess on what could cause a crack in the crankcase shown in the image? Stress or possible internal foreign body?

Thanks for reading. Captain Jon of Port Motueka, New Zealand. ⚓

you might consider having the crankcase welded or contact the dealer and MV and throw yourself at their mercy.

I'd probably weld it up, too.

It looks like it cracked at a stress riser where the swingarm, frame and engine come together. If there were a missing spacer in there, it could cause stress and eventually a crack I suppose.

If MV is taking it on, get a limit of liability on the repair if they aren't going to simply warrant the repair.

BTW, welcome! My wife and I have good friends in Palmerston North...we love NZ!

Nice job on the dye penetrate test....right at the motor mount.!!!

Loose motor mount bolt? improper spacing at assembly? Porous casting?

MV, like any other manufacturer, will only pay for warranty repairs performed by an authorized dealer....so if it is under warranty you will have to take it there.

How many miles on your bike? I would expect MV to be curious about this as it is a very unusual failure.

I used to be fast....now I just dream about it.

Thanks everyone for your feedback on this dilemma.

Very good point here: Would I ask the MV service centre, their NZ/AU distributor they answer to, or MV Agusta Italy, in regard to limit of liability of the repair?

I've done 30,000kms in two years. Its been great apart from Sprag Clutches. (Last one took five months to gain.)
Issue is the only MV authorised dealer is other side of New Zealand. Without being near it, my bike would live in there for months at their mercy.

Fishcookie;
I can weld just about anything.......
That said I'd groove the crack out a ways and clean it off with lacquer thinner

And repair it with epoxy, make SURE IT'S CLEAN 1st

I would be tempted to use something with some flex to it.

Some motion or stress caused that initial crack.
