Re: Fuel pressure regulator

Hi Tony. If the regulator is leaking then plugging the reference port will lead to a build-up of pressure wth the result that the fuel pressure will increase above the required 3 bar value. Looking at your photograph I can't make out the port arrangement on the regulator but if it has only two main ...

Re: Fuel pressure regulator

For fuel injection systems the port on the top of a regulator is to provide the reference pressure for its operation. Often connected to the inlet manifold (on a car) for the Guzzis it just goes to atmosphere. If there is petrol coming out of it then there is a fault in the regulator, probably a per...

Hi Brian,
I sent it to your Hotmail address (above).
I have just re-sent the email - it has a zip attachment so check your spam folder because the zip file may trigger the spam filter.

All the best, John.

Re: T4 Wiring from old site

Hi Brian, it must be said that Guzzi do their best to confuse. The sensor I have is coded : brown (positive), black (ground) and blue (signal). The Guzzi wiring diagram shows : green (positive), blue/orange (ground) and grey/white (signal) If you still have the 3-pin plug that is on the end of the s...

Re: T4 Wiring from old site

Hi Brian, well done getting the engine and dash wired up. The easiest way ahead with the speedo is to abandon the ABS unit and use a pickup from a non-abs bike which fastens onto the CARC unit and picks up on the bolts that hold the brake disc to the rear wheel. You can get this sensor (use a GRISO ...

Re: Newbie

Hi Colin, there are a few things to think about when choosing a donor bike. Firstly there are two-valve and eight-valve engines. Pre 2008 they will be 2-valve, Stelvios will all be 8-valve (they are called 4-valve, but that is just to confuse), and Norges, Sports and Grisos could be either. The rock...

Re: Nova racing reverse gearbox

The box has a chain drive to a layshaft (below the main shaft) and then gear drive back to the output shaft. The selector lever either dogs in the reverse gear or connects input direct to output for forward drive. The lumpiness is almost certainly the chain running tight and it will loosen with a bi...
