If you have a fuel injected model with an internal fuel filter and pump, unless it has been changed the filter will be a Mahle KL150 which is half plastic.
These can and do split at the join and this will stop the bike immediately, no warning.

For your safety it is well worth changing that filter for the all metal Mahle KL145.

I just opened the tank on my 2021 V7-850 to get ahead of impending fuel filter melt down . Seems Giuseppe might have learned something



It is not inconceivable the dealer got ahead of me at the 600 service. However, given Via Moto don't know the right oil, can't measure and whoever did this does very neat pipe hose crimps, I think not.

Caveat Emptor of course, but I think the further on your bike is from November 2021, the more chance you have of not worrying about the fuel filter.

Can I ask what oil they used instead and how you found out they can't measure the right amount?

I only ask as I know the Piaggio group are tied in with Castrol but the recommended grade (10w60) for my V7 is not available in the U.K. (information from Castrol) so I'm guessing all dealers use something else?

I do my own servicing anyway and I am using an alternative brand to keep things simple- obviously the equivalent spec etc.

The bike wouldn't change from 1st to 2nd until you'd ridden at least a mile on cold mornings. It had been like this when brand new, but by 600 miles only a little awkward. I checked the first service invoice which showed 85W90 while the manual not only calls for no change until 12000 miles but then 75W140.

I changed the gearbox oil. 

Out came 600+ ml of brand new oil, in went the correct 500ml of the correct oil and bingo, first to second at 3 degrees with barely a clunk.

The engine oil was right to the top of the glass, but that only suggests a slight angle on their table or Muppetry associated with people who think more is better. I put about 100 ml less in when I did the 8000 service. Brand makes no difference unless you do buy Sum-Yung-Gi "Best service Oil" from the auction site. Think I used Motul.

I will be getting the engine oil analysed at 16000, probably next summer. Results will of course be posted. My bet is you can safely double the service interval in the UK, but we'll see.

I have read elsewhere that they stopped using the wrong fuel filter in 2019 on V7 IIIs. I have no intention of disturbing my quick fuel connector to check….I don’t believe V7 850s have ever had the plastic/metal ones.

Sorry, forgot to say that I use Motul 10/60. Opie Oils sell it. It has the right spec. The key thing about gearbox oil is that it needs to be GL-5 spec, not GL-4. Castrol do that. Mine had the right quantities in both the final drive and gearbox, or near enough. A fair bit of swarf came out of the final drive but the gearbox had nothing in the filter or on the plug. I don’t believe the dealer changed these oils at the 900 miles service (nor is it specified in the schedule), but I wanted to do it anyway at the annual service I carried out.

Don't know who in Castrol told you that.

Castrol Edge 10W60 is readily available.

Castrol Edge 10W60 is readily available.

Hi, it was from their technical department, I asked the question as I have read quite a few people run these on car oils as the gearbox is separate (like a car) but basically, they said Edge is a car oil for a reason and not ideally suited to the higher running temperatures of an air-cooled motorcycle- which as the Euro regs. get tighter and engines run leaner the engine running temperatures increase along with it.

I also spoke to Tim (via email) at Opie and he agreed that there was no 10w60 motorcycle specific Castrol Oil available (or listed by Castrol) in the UK and so recommenced Motul 7100 which I've been using.

To be honest with only 2lts in the engine, 500ml in the gearbox and 170ml in the final drive for what it costs you may as well do the lot at every service.

Usually, by "motorcycle specific" they mean compatible with a wet clutch.
Very surprised a fully synthetic oil is not up to it.

I believe it has more to do with the shear capabilities of the oil (usually) lubricating the gearbox on a motorcycle rather than a wet clutch - some fully synthetic oils have caused the clutch to slip on a few Ducati bikes apparently. I don't have this issue on either of mine as the Monster has a dry clutch too.

In reality I am sure that a fully (or semi for that matter) synthetic car oil would be more than up to it but as it's not a 'motorcycle' oil I guess Castrol won't recommend it for fear of legal action if it all went wrong. 

Interesting stuff though- thanks! I'm still getting my head around these Guzzi thingys Wink

But are Castrol saying it's not a "motorcycle" oil because of the gearbox issue?

Dumbing down from the experts there Thumbs Down

There is no such thing as "motorcycle oil". 

There is SAE 10W60 to JASO MA, MA2, API SG and there are other oils. The JASO spec sets resistance to shear, heat peaks and a host of other stuff including modifiers that will give trouble with wet clutches.

Castrol Edge does indeed not list these in the spec. 

Castro Power 1 racing 4T does as does Motul 7100.

I looked at Castrol Edge and decided it wasn’t right. Motul 7100 meets the spec exactly and is what the supplying dealer put in. A different dealer put the same in my brother’s Roamer. Not sure that Castrol Racing 4T is 10/60. I used to use Valvoline 10/60 in my 865 Thruxton. Halfords no longer sell it but it might meet the spec too.

Just managed to get the tank off my 2019, 17500 mile old V7iii Carbon as I need to get under there to wire some lights in. Very difficult to get the tank off. It was glued onto the rubbers (well it felt like it!) thought I'd better check the fuel filter whilst I was down there. It's half plastic!!! Damn. Lucky it's lasted this long. Ordered replacement. If you haven't checked yours, take a look and replace it if its plastic. Mine was very swollen and a right basket to get out of the tank.
If it was easy, anyone could do it...
