Hi all.

Any comments on oil filter bursting on the F4. Not a once off thing. It has happened 3 times on this bike. Yes it is a original filter for the MV. Any help welcome.

Hi Jorge, I had the same thing on mine last June, just slowing down after a high-speed motorway run..... the filter split, spewed oil onto the lower fairing inner, from where it plastered the rear tyre. Lucky not to come off or seize the motor.... Checked with the local MV dealer and it was one of the "upgraded" filters, never did discover what caused it. The replacement one's been fine so far (argh, famous last words!!!!) Still, who buys an MV in order to live a boring existence?? (but hopefully not a short one!) I thought mine was a one-off, the dealer had never heard of it happening before. Be interesting to see if anyone else has had this?

Hi guys,

This is a very well documented issue that shouldn't be happening anymore, it was resolved a cople of years ago. All I can think is that all these new dealerships havn't got the info, or just havn't read it.

THE FILTERS DO NOT SPLIT OR BURST, they start to spin off dispite being done up to factory spec.

The solution is very simple, a collar is attached to the filter, which when done up correctly stops the filter from turning. If this is forgotten (it comes with the replacement filter) or not fitted correctly then the original problem may occur.

And yes - lots of people had this happen, never heard of anyone getting hurt though. It seemed to happen as people come to a halt for some reason.

Yes the do I had one slit right at the front where the socket fits on the mechanic that did a lot of work on MVs said he had several split at that point not a big slit but a very small slit but it did drip out onto the exhaust fortunately I just got home when i noticed the smoke the filter was not loose it was a b**st**d to get off I now keep a spare one with the clip that stops them unscrewing

Everyone might want to consider what most road racing organizations require: a big hose clamp fitted around the filter and safety wired to somewhere convenient on the engine so that it cannot spin off. Just my 2 cents.

Don't think your filter was STD if it had a 'bit for the socket to go on'. They are plain.

Yo! If you do it right the first time, your filter will not go off. You must make sure that it is tight, holds well and collared so that it will not move from the bike's vibration. Hoep this helps, buddy!

Guys, my filter was a genuine original MV item (black with the MV logo in silver). It had been fitted at an MV authorized dealer as a result of the filter recall prob (i.e. it was supposed to be the "fixed" one) and it had the clamp fitted too. It didn't come loose, it split at the front corner like Les's. How do I know? Cos after getting the bike to my friendly neighbourhood bike spannerman, we removed the fairing and fired up the motor.... result: jet of oil onto floor in a graceful arc, from small split in front corner. And yes, it was screwed on tight..... not loose! Was worried it might have been the oil pressure relief valve sticking, but as I said in the earlier post, it's not happened again. Still, I've "done a Les" and got a spare, just in case! So what do we think? A batch of faulty filters? Stone damage (unlikely)? Divine Retribution for not riding a Harley? ...any ideas?

Regulator. Mine spit the filter (and then the replacement filter) off the bike.
