Mikuni Carbs vs manifold vacuum to Digiplex

Post by micklm »

Hi all,

First a thanks to everyone for the help this board has already given me in deciding to buy a Paso. There really is a wealth of information here.

My question comes from the fact I have a bunch of leftover 600SS spares from another rebuild/project bike that I'd like to use on the 906 - especially the Mikuni carbs and 17inch wheels :)

But........when fitting the Mikuni carbs from a supersport, how should the intake mainfold vacuum input to the digiplex be dealt with?

If removing the Paso airbox and using pod filters can the vacuum take-off points on one of the supersport intake manifolds be used? (i.e. the holes normally blocked by a screw or used for carb sync)

Or

Should you try and retain the paso airbox connected to the mikuni's? Is that possible?

Or maybe I have got it wrong and there is no problem??

Cheers,

Mick

It is better with pictures I think.

What to do with the line from the digiplex (red arrow on Paso parts diagram) when installing Mikuni carbs?

I think it is OK to plug the hoses on the paso parts diagram (blue arrows) to the manifold holes on the 900SS parts diagram (also blue arrow).

Or am I making this all up in my head? Is is really required? Has anyone needed to do this?

cheers,

Mick

Just connect it to the manifold as you have it circled. You might want to run it to both manifolds so you get a smoothed out vacuum.

Thanks mate - good point on linking to both manifolds.

Will use the existing plumbing on the Paso to try and match the minimum inner bore / restriction for the sensor.
