Sorted, I had connecting the fuel line to some sort of vaccum stuff on the carbs

Bike's not running yet, but it's farting loudly

Muppet

What is it for btw? I understand the need for vaccum to power the pump, but what does it do to the carbs as well?

[skidlids]

Tonio is the CV (Constant Velocity) carbs they will only suck up under vacuum and then drop again if the air below them can increase and decrease in volume

[Tonio600]

Are you saying that even though I am using an electrical pump, I still need to connect the vaccum inlet on the carbs? That would explain why she would not fire up...

[skidlids]

Not sure what vacuum inlet you are refering to, I was thinking of the ones that have the black bobbin type filters on them

or did you originally connect to the overflow hose

[Tonio600]

Sorry Kev, I was even more confused than I got you confused

I actually connected the fuel delivery to the carbs breather

And after swapping the HT leads, the engine's now running. Roll on 2009

Anton, maybe you should mark things or take a few pics before you pull them apart, or is it just the way the French do things

[Tonio600]

I don't like taking notes, marking stuff, etc... It just does not help me to understand what does what. Now I know that Mikuni CV carbs have a breather
