Had a little chat there on your own? :lol
I normally use my ignition key, it seems to fit perfectly to undo it.

A quick note on balancing the carburetors
Do not worry about getting the vacuum Hg figures the same as the book, it is far more important that all the gauges read the same.
All gauges reading the same means the throttle butterfly valves are now synchronised the present engine condition. :woot
The figures in the book often have the idle speed, set to high or to low depending on the type of gauges used, weather/temperature, height above sea level and/or engine wear.
It is the setting of the idle speed at the factory in factory conditions, :eek not the conditions most owners have in the man/woman shed and definitely not the conditions in my garage. :lol
Set the TPS after setting the Idle speed.

All,
Anyone give me an idea as to if this is normal behavior...
In Neutral on the center stand....i twist the throttle all the way open and it struggles to hit 7500rpm....even if i twist more....

No, it should rev as high as you want it too, way past 7500rpm.

Have you checked the Air Filter? If in doubt replace it.
Could have a problem with loose leads on the plug caps.
Re: Low RPM cough cough.... - anutz - 28-02-15
So,
K and N filter installed....
When i blip the throttle the vacuum pressure DOES hit 230 ish...
At idle they are still at 180 ish...
Any way i will be running it into a mechanics locally soon so will see what they say
But it is my first 600'cc so this might just be me

Did you not read my reply here http://foc-u.co.uk/index.php/topic,15985.msg184456.html#msg184456 :rolleyes
Re: Low RPM cough cough.... - anutz - 28-02-15
OK,
changed the air filter for a K and N, have not had chance to ride it yet, but it does indeed sound better, less choked, and no sign of any stuttering - hopefully that translates to some nicer behavior when riding at low RPM but its tipping it down here so i am not going to test it tonight

Unfazed...
I did see your last reply....not sure what you want me to say
I don't really case about the pressures any more - was just updating people as to where i am at now...the K and N seemed to make a difference - will know when i ride it soon, certainly sounds nicer and richer

Re: Low RPM cough cough.... - anutz - 04-03-15
All,
So i have been out tonight ( little cold!)...
Although the K and N sounds nicer ( i think...) it still has made no difference to the ride at low RPM
The point was made earlier in the thread about not being concerned about the pressures in my carbs....
I know it is important they are sync'd but, why is it so un-important that they are roughly 50mm down on what they are specified at in the manual....?
I know conditions where this is quoted are based at the Yam factory but is there no valid reason to consider the pressures....
Has anyone else measured there pressures, and were they near the quoted values 230-250?
I will check the TPS, the Idle is set fine, so no issues there
