Do you have a reference part for the pilot jets?
I was going to take this one
http://shop.xs650shop.de/front_content.php?idcat=8
PartNo: 48_0609
but I noticed my pilot jets have no holes on the body while this one has. This is for a XS650 but it should use BS34 like the 400dohc.
I know for Keihin that's not an issue, dunno about Mikunis.
I sourced my jets from a local shop ( http://www.siriusconinc.com/ ) and don't have a part number. I paid CDN $3/ea. for them, but I have preferred customer status with them.
I've been told that the holes in the side don't matter.
