Hi Folks... Question. 

 

I'm a new owner of a 2000 V11 Sport. 

I love the bike, it runs great no issues for 

the duration that I've owned it. 

 

When it came time to service the bike I 

purchased all the supplies that I needed

to do the job including a fuel filter.

To my surprise the fuel filter wasn't 

there?? Plus the fuel pump was located

under the spine. 

So the previous owner ran the bike 

without the fuel filter. 

Is this a common practice? Am I at risk 

of damaging the engine without a filter?

I think you run the risk of plugging the injectors, the filter is an aluminium can also under the tank.

It is not a common practice with ANY fuel injected bike.

The early bikes had an external fuel pump and fuel filter. Both should have been bolted to opposite side of the spine as I recall (not sure...).

The later bikes had the pump and filter inside the fuel tank.

Running an fuel injected bike without a fuel filter would be a bad idea. The holes on the injectors are very small and it would not take much to clog them. And you gain nothing by doing so. It would not be faster or make more power.

Some bikes with the external fuel pump were shipped with it above the frame (downstream of the filter) and the filter below, most others, the other way round. It even suggests this in the workshop manual: so the two locations are interchangeable. Some people believe moving the fuel pump above the spine (and so the filter below) helps avoid vapour locking when (not) starting in hot weather. I believe the consensus (from this forum) is that replacing the solenoid petcock with a manual one does more to help that than anything. So you might want to do that too while you've got the fuel system apart!

Very likely your filter is above the frame/ under the fuel tank which will require its removal.

 

Check this link, but don't be overwhelmed by the list of "other" things you could do while the tank is off:

You can search near the oil cooler also. Some had it there.

If your bike really has come without one it doesn't mean anything is damaged or worn. First it's an unlacquered plastic tank, second you don't fuel up out of canisters, third several filters are built in anyway. One in the petcock, one in the pump, one in each injector. You cannot run dry the tank, so fourth there's always some sump left where debris could settle.

Good point, Hubert, good point.

So why do we religiously replace the filter every year?

(Rhetorical question only)

Thanks so much for the advice! You guys are great.  

 

I think I'll install the filter above the spine since 

the bike runs fine with the pump located under the spine.

 

Thanks "docc" for the "Tank Off Maintenance Checklist"

I'll be going through the list the next time I have the tank off.

 

It's presently - 20 F up here in Canada. It'll be awhile before 

I can hit the pavement for a ride.

Welcome to the forum Walt ..... and welcome to another Canadian!!

 

While you are waiting for spring (several months away this year from what I see) ..... we all love to see pictures and stories of your bike.

 

Where did you buy your bike? I saw a green V11 for sale at the bike meet at Paris, Ontario last summer but that one looked a little rough. 

 

cheers

Hi Jim 

 

Funny... i was at the Paris show too. Had a good chat with the 

guy who own's the green V11. I felt for the guy... He was really

hoping to sell his bike that day. Seemed like needed the coin. 

 

I purchased my V11from a gentleman in Toronto who is 

a member of the Ontario MG group named Fillipo. 

He has a few V11's and other Guzzi's.

Wait, I recall hearing that the newest thing with some BMWs is that they don't have fuel filters at all.  Something about the gas is so good nowadays, blah blah....

 

Not sure if it's actually true, or just loose talk at the pub.

 

 

 

Actually, my BMW doesn't have a fuel filter either, until I added it.  Didn't have an oil fitler either.  But it's a 1958 R50.  Funny how things have come circle.

Many manufacturers have stopped using replaceable fuel filter. They are now built into the fuel pump module.

Yea, just like my '58.  It's a mesh screen, right?
