Hoses.

[John Lawley]

what are the 2 hoses one small one larger that feed into the plenum chamber on the airbox after the flexi hose behind the flow meter? I have an alloy pipe and an induction filter on the way and want to know what to do with them, i think there the crankcase ventialtion but haven't encountered 2 hoses before.

thanks

The small one does vent the crankcase from way down, I cant remember exactly what the larger pipe does but from memory its recirculating from the top of the throttle arrangement.

I would re-connect both when you fit the new unit to avoid any issues; as to where will depend on the new unit. Note that the pipes are push fit to plastic and the plastic isn't the toughest. I broke mine.
