Hello fellow Guzzi riders, this is my first attempt so please bare with me.
When I first bought my 2000 V11 I was horrified at the amount of fuel it was using around town. The next tank full was smooth fast country riding and hey presto fuel usage was quite good. The only problem seemed to be the low speed running and the fuel tank capacity.
Around town the fuel light was coming on after only 200klms and in the country it was 245klms, on filling up the tank usually took around 15 litres. One day I had the engine spluttering as I turned into the servo and it only took 18 litres or 4 imp gals to fill it up.
Rechecking the owners manuel confirmed that the tank capacity was suposed to be 23 litres or just over 5 imp gallons.
I've since found out through the V11 Le Mans page that the fuel is trapped in the right hand side of the tank where it returns from the fuel injector loop.
Originally my plan of thought went somewhere along the lines of the fuel pick up being too high in the tank, a common enough problem in older Guzzi's and easily fixed. However this is a really hairy problem to solve. How do you get the use of that extra gallon of fuel from the RHS of the tank. I once had a Honda CB175 and the tank actually had a link pipe between the two sides, of course the older Guzzis have twin linked fuel taps and I have heard of some folks useing this as a twin reseve by only turning one reserve tap at a time. I'm thinking about it.
One of the ways to help with the fuel problem was to get the Fuel Injection remapped so that the fuel is used more efficently.
So the bike was booked in for a thorugh going over which included the throttle position sensors, primary enriceners and a remap.
Unfortunatly I haven't had much chance to evaluate the improvements though initially the throttle response lower down the rev range feels alot crisper, probely cause it's not now being drowned in petrol. I'll let the fourum know more in a couple of more rides.
