Re: Cali EV fuel injection

Just a word of caution on using silicone sealants for electrical / electronic work. There are two flavours of RTV silicone which have different inhibitors - either acetic acid or alcohol. The acid one (smells of vinegar) releases fumes during curing that react with copper wiring and circuit boards t...

Re: Air pressure (MAP?) sensor?

Hi Colin, the pressure sensor is an APS-1 and I make them especially for the T4. Drop me a pm for price and details. It is actually an ambient pressure sensor (rather than a MAP sensor) and communicates with the ECU via CANBus. It also looks after the immobiliser function of the Guzzi dashboard (als...

Re: New Member in Northern Ireland

Well, goaded into action by Tony ..... Any of the CARC bikes are suitable as a T4 donor - Norge, Sport, Griso, Stelvio and Breva and some others that are more rare. They all have the single sided swinging arm rear suspension and a monoshock spring / damper. There are two flavours of engine - the two...

Re: Oil cooler hose fitting size?

Hi Colin, 'Scuse the vagueness but it is a while since I plumbed in the oil cooler. I seem to remember that the Guzzi pipe fitting was an unobtainable size, but the adaptors screwed into the cooler were a standard thread so I replaced the adaptors with standard AN adapters and used the self-assembly...

Re: Build tread (kind of)

Hi Berglind, The work / life / Triking balance is always difficult - we just need 30 hour days. With a 2004 bike it is difficult to know weather it had a lambda probe or not - they were introduced around that time, but different countries got them at different times. If you look at the label on the ...

Re: Build tread (kind of)

Hi Berglind, I can help a bit with the fuel injection if you need. There is a modified ECU map which suits the Trikng engine installation and, if needed, can remove the need for a lambda sensor (if your country's approval system allows this). The usual air cleaner approach is to use two K&N filters ...

Re: Swingarm removal

The bottom gearbox bolt is notorious for corroding. You may need to grind an end off or part it in the middle if you can get to that bit. Then replace with new bolt. It does go all the way through with a nut on either end. The pivot bolt is screwed into the CARC casting on the right hand side so be ...

Re: Will I fit in a T3?

Hello Brian,
My type 4 is almost finished and is "on the road" if you want a look and see if you fit. I'm a bit nearer to Donny (about 50 miles) at Matlock. Drop me an email if you want - john at jtdesign dot net.
