exup spacer missing

[kerb]

Hi All

looking for a bit of help , i recently bought 03  fazer thou
so i was getting the error code for exup valve when ignition turned on ( rev counter going to 700rpm)
so found that exup valve was seized
so i striped it down and  greased it all up now moving freely with hand
but when i tightened up all bolts to torque setting found that valve was very hard to move
so i took it out again i found that the spacer was missing 

( see spacer on this pic, red arrow pointing to it in pic r/h top )

and first part on left in this pic http://www.cartestsoftware.com/fz1/image...ance04.jpg

so i want to make a spacer for it

so my Questions are
is this spacer the same diamater as the bushing thats inside it
what i mean is , is the outer diamater larger than the bushing thats inside it
( this bushin doesnt normaly come out when valave removed its not in any pics

thanks for any info kerb
