Mine were down too. I just made sure that they were balance up as close as possible. The bike is running excellent, so i'm running away until something goes pop!!

Probably wear and tear over the last 10 years.

I had a similar issue but opposite - my readings were between 28-30 if I remember correctly. The only thing I can think of is the mixture settings?

If it ain't broken, then don't fix it. If the bike is running fine, go out and enjoy it. Life is short to be going around paranoid.  :crazy

Personally, I'm not going to mess around with my mixture screws or anything else until I experience a noticeable problem with the running of my bike. Right now, she is running sweet as a nut. She starts on the button without choke every morning, and ticks over nicely from the off and there isn't a stammer nor a stutter throughout the rev range.

I am not saying that you shouldn't heed to obvious or serious warning signs like if you found metal fragments in your oil, or load knocking sounds from your motor ect ect. But what I am saying is that you have to be practical and allow for a little wear and tear too and do a sort of "worst case scenario" type of assesment to what's not right. Like, it's not going to be life threatening if your carbs deteriorate over time...you will just have to get new ones. But if your engine or brakes seized and if there was tell tale signs that you ignorned, then that could be detromental to your well being.....if you get my drift.

from memory,a bad one.......dont you set the readings on no1 cylinder using the idle screw before balancing and then readjust when finished.....ie,do the balancing when the readings are between 23-25.....or is my memory worse than i thought  :rolleyes
One, is never going to be enough.....

RED your right but it would mean the engine running at around 2500 revs this would seem high to me b ut they are ballanced so guess its all good
if it aint broke, try harder!

Don't worry about it , it is far more important that they are all as close to the same readings as possible.
It is a measurement of the vacuum at the intake manifold and since the manual does not state what revs the vacuum is to be set at the figure is meaningless. Many machines have the vacuum set at a very high idle as the vacuum reading are to low to read properly at tickover speeds. I have found on the Fazer 400 I have to set the idle to 2000rpm to get readings with the Morgan carbtune.
As longs as you can read the measurements and they are all as close to each as possible then check the TPS setting and ride on :sun
