P.A.I.R System and help identifying part

[sledge]

Sorry I cant help anymore........the setup you have applies to USA bikes, I am in the UK and we get something different 

[rg500gamma]

I am thinking ,  there was no drilled and taped holes for the steel hoses  that bolt to the engine ,  there is two places  on the engine  (side by side )

this is a big clue  as  to never having  the  2nd  valve  assy. installed  on the bike .

[rg500gamma]

The ports have been roughly cast but they haven't been finished machined along with the tapped holes that should hold the PAIR pipes and their flanges in place on the cylinder.

Your bike has never had the PAIR system fitted but does have the evaporative control system fitted and the black cylinder in the pic is the charcoal filter that absorbs fuel fumes.                                                                                                                                   

Cheers  Sledge  !!!!!!!!!!!!  +1  again   ,  excellent   wording  and  excellent  knowledge  ,  kind regards  from us  on the other side of  the  pond  ..........

Cheers  Sledge   !!!!!!!   +1  again      spot-on

picture #1            ok this hose on top of the left carb , you have a open hose ,  I  think  this hose goes  to the bottom of the airbox  .

Concerning the hose with the round plastic piece attached to it:

Looks like part of a calif model, the EGR.
Just cut out a square out of the yellow of a yellow/green sponge, and insert it there.
It's some sort of vacuum line, that over time has sucked up the filter in the engine (sensitive to fuel, mine also worn the filter).
I used a synthetic sponge as filter, works fine, sponges are easy to get, and work fine as air filters.

Leaving it open allows debris to enter the engine.. not good.

You can't block it, or the engine will stall.

Hi  Meelee , what year is your gs500 ?  the airbox  on bikebandit  diagrams  shows  two rubber  hoses  one on top and one on bottom  ,  boy  a few  different  set-ups  as  I have  full  emissions  california  gs500f ,   back  to work ,  ( took  a coffee break )   hey  Meelee  take care  have a  great weekend  rg500gamma 

[rg500gamma]

the hose in the diagram on top (airbox )  is  the  valve cover vent hose ,  the  bottom hose on the  airbox  looks like a catch hose  ,  diagram  on  2002  year  from bikebandit

2004 calif model.
perhaps the prev owner didn't know, and installed a reg airbox.
the bike had some mods and miles before i bought it.
