I'm new to this, and know that asking about vaccum petcocks been heard probably 1000 times,but did follow directions from XJ bikes and cleaned and rebuilt petcocks on my 1979 XS1100 standard. Question, said to align small slot hole in plastic spacer to bottom rear of petcock. My spacer had just small hole which I aligned with small hole in petcock housing but is towards the top is that correct.

There is a small hole in the body of the petcock that that hole should align with. Also, don't forget to put the springs back in. I did and now I have to re-do it as it is not vacuum operated any more.79 SF 3H3 Engine, 145/45 Mikuni Jets, El Cheapo Pod Filter Mod w/ EMGO Pods, Coil Repower w/ Dyna Coils, Accell Wires and Side Gapped Plugs, 78 Mech Advance, 4-2 TurnoutsComment

Thanks for the help. My spacers are different than the one in picture and aligned to the top of small hole in petcock body & small hole in diaphragm and spacer match together. All Together running great .79SF XS750; 79F XS11Comment
