Re: stuttering fzs 600 - Andy FZS - 27-08-12
The determination of a gas pressure that is less in magnitude than the pressure of the atmosphere. This low pressure can be expressed in terms of the height in millimeters of a column of mercury which the given pressure (vacuum) will support, referenced to zero pressure. The height of the column of mercury which the pressure will support may also be expressed in micrometers. The unit most commonly used is the torr, equal to 1 mm (0.03937 in.) of mercury (mmHg).
Pinched this off the net I think it explains...............

......i know i need to aim for 240hg , but not sure of the reason why :\ ....are all bikes set to this standard or do they vary.....no mention in haynes book of lies :rolleyes
Re: stuttering fzs 600 - CRH - 27-08-12

Re: stuttering fzs 600 - red98 - 27-08-12
just serched pilot screw on here and found a post by GNASHER that ive read before and then forgot about :\ .....topic title,RUNNING PROBLEMS / TPS ISSUE .lots of info here and easy to understand, THANKS GNASHER 8) . i need to pull 230-250 mm at 1150-1250 rpm,and must have pilot screws set correctly for balancing
.... well worth reading this post
Re: stuttering fzs 600 - CRH - 27-08-12
that sounds spot on then!!! theres your 240hg..and at idle speed !!! does sound like factory setting after all?....wasn,t there mention of a maximum discrepancy between readings??
cant find my notes?..but think it was bt ...10% between cyls max!!

reading my scribbles it is indeed 10 between cylinders
[size=78%]......10 what i dont know [/size] :o [size=78%].....will find my gauges tomorrow,they might give me a clue. [/size] looks like i will have to alter my pilot screws to 2 turns out for the balancing :\ [size=78%].....anyone done this with carbs on the bike ? not a lot of room in there [/size]
Re: stuttering fzs 600 - CRH - 27-08-12
i would think thats 10mm hg on your scale red!!....i would still try the settings you been given first mate?....just may be good!!!!!ps, if you set all your carbs the same,ie 2/2 1/4..or even 2 1/2...i would leave them at that and balance them you could allways do fine tweeks later if needed?.....got to be nearer than what you had b4?...ie 4turns out!!!!!.....i think you will struggle trying to adjust them in situ???

Re: stuttering fzs 600 - Andy FZS - 28-08-12
I managed to set 3 out of 4 screws ok but will need to remove the starter motor to set the 4th so I've as yet not done it. I've added it to my to do list for winter

had a look myself tonight
and like you ill take the starter out to reset them ........how many turns have you set yours to
Re: stuttering fzs 600 - red98 - 28-08-12
had to cut the front hedge this evening as swmbo was getting a bit frosty...so less time in the garage...but i did manage to put the coolant in and sort out my carb balancing gauges......will need to set mixture screws to standard for test,4 turns out at moment :eek been like that for the last 10 years that i know of
so will set them to 2 1/2 slightly richer than standard the easiest way to reset them seams to be to take the starter out and use a small flat bladed screwdriver
will see if i can do that tomorrow
Re: stuttering fzs 600 - ade the blade - 28-08-12
no no no............................leave the starter motor alone. :rolleyes get yerself one of those titchy spectacle repair kits for a quid or so and inside you will find a nice lickle flat blade screwdriver about and inch or so long that works a treat.....wouldn`t be without mine. or a small flexi shaft jobby !
Re: stuttering fzs 600 - Andy FZS - 28-08-12
I set mine to 2 1/2 turns but I think that's standard for mine (03) I tried using a small 1/4 drive socket screwdriver but couldn't manage all 4.

Re: stuttering fzs 600 - red98 - 30-08-12
re set the mixture screws last night....what a pain in the a*s :\ ........did three of the carbs with a small screwdriver no problem
cylinder no 3 was a pain,can see the screw easy but once i get my hand in there i cant see bu**er all :\ so took the starter out,which helped but still could`nt adjust,ended up loosening the inlet rubbers on the carbs and easing the carbs back and as high as i could :\ i was than able to adjust no 3 all back together now and ready to balance the carbs
all being well i`ll do that tonight and also do another compression test to see what difference re-seating the valves has made
