Thanks

I have downloaded the Corsaro ZZ manual from the members area. Some places I have trouble understanding what part of the engine is shown, in some of the little black and white photos, there is sometimes no context. And sometimes not a photo of the thing I'm looking for :D Thanks for the photo you po...

If you are using solid aluminum gaskets then no need to re-torque. If you use the early type metal&fibre ones (which some places still sell, e.g. in with those "complete set of engine gaskets" often vacuum wrapped onto a cardboard backing) then you should definitely re-torque those as ...

Thanks Guys,
Very good explanations, much appreciated.

The cams are chain driven from an intermediate shaft, I can see, but what drives the intermediate shafts from the crankshaft? Is it gears?

Thanks Tom,
So that one does both functions, crank position as well as speed?

I am (slowly) learning the detail 1200 motor.

Hi All,
The 1200 is a bit new to me, so I'm looking for where to find the crank position sensor and ignition triggers, can't find them on my wiring diagram. Am I missing something?

If you are interested let me know and I can email you the photos. I don't seem to be able to upload them.

They fit at the front of the tank. I have one pair in the black style.
I will attach a photo when I find one that will load onto the website.

Yes on the standard system Red is where the positive current will appear. Yellows are where negative currents will appear. The flow of those currents around the circuit Red > Battery positive > Battery negative > Reg.rect. > Yellow and back through the stator to Red where it began is controlled by t...

With the standard system; When the ignition is off and the engine isn't running the voltage from the battery comes through the standard reg. rect. and imposes itself onto the stator (Yellows and Red). It doesn't reach the part of the stator thats for the ignition (Green and "Earth") that i...

I believe with the standard reg. rect. the stator windings are live all the time even with the engine not running and the key out. Some people used to introduce fuses in case of faults. Donkey's years ago I did sit outside a pub with some other MRC members and watch as my bike stated to smoke from t...

As Mr Moto says, the Brown is 12V flowing INTO the regulator rectifier FROM the battery. As a reference point to measure the state of charge and allow the reg. rect. to regulate the AC power from the stator (2x yellow wires and 1x red) correctly.

...a new battery - Yuasa YT12B-BS which is good enough ? I would have thought a 12 Ampere hour battery would be capable, we have a 14 Ampere hour battery in ours. While Ampere hours (capacity) is important, what is perhaps more important is CCA or Cold Cranking Amps (electrical flow rate) so maybe ...

Thanks I wouldn't have thought of that. Useful to know.

How many ohms across the starter relay?

And is the circuit that pulls the relay in, pulling it in 100%?
