Righto, this is how my bike is setup now and that's how I got it.

Solenoid number 1; top outlet, runs to a T piece, then onto the X piece (into the r/h outlet which has the jet in), the other outlet on the T piece runs via a little black pot (part number 14 in this picture) to the bottom outlet on soleniod 2

Solenoid number 1; bottom outlet runs to a T piece, that splits off into two and they run onto the carbs, connecting into the two points nearest the slide.

Solenoid number 2; top outlet, runs to the X piece (into the top), the X piece then runs to the two other carb points (quite near the front).

Is that right? It looks like the pictures.

Is there any point in swappig the X piece for the red HRC one?

Does anyone understand how or what that lot does?
