for who remeber the vacuum pressure when they synced thier carbs how much was it ? mine sucks at 34cm HG and throughing my synpro out of range so I had to use air guage instead is this normal or ? just tell the pressure you were getting if you know it.

 

as far as i recall, what ever the pressure reading on carb 3 is, thats what you set the rest to. thats the only 1 that cant be adjusted.

 

I just did mine a few days ago. #3 was up there and as I started bringing the others up it started coming down and they all met somewhere a little below what #3 was originally at somewhere in the upper 20's to low 30's although I don't remember where exactly. As I understand it, it's not so much where they are at as long as they are all there together.

 

so around 34cm hg is not that bad after all, I know the value doesn't count as long they are almost equal but most of the bikes I've had had less pressure than this one so I was wondering if something basically wrong so thought to compare with everyone else tho
