Update on old 'low revs issue'

[JayDub]

In relation to my earlier post regarding the running problem at low revs:
http://www.tigertriple.com/forum/index.php/topic,14400.0.html
As well as checking the valve clearances (OK), I have also done a full ignition circuit test using the dealer tool (thanks to a good mate lending it to me  ) - igniter, coils crank position sensor etc and circuits - ALL tests passed.
I also checked the primary coil resistances and given that I don't really know what I'm doing, They are supposed to be 0.63 Ohm -/+ 10%. At the >1 Ohm setting BUT my multi meter only goes down to >200 Ohms, so at that setting I got the same reading of 01.1 Ohms on all three, which I would assume is good that they are all the same spec? - Bixxer?
... the problem is still there 
I suppose the next logical step would be to change the carb slides, as Mustang suggested (and have I any cash left in the bank  )

They're not cheap as only Triumph used that size

Yes, 36.80 ea.... + shipping, I even tried to get a carb assembly via parts sell off but all sold out, and now obsolete Mmmm

Try www.triumphparts.co.uk
They sell used parts?
or triumphant

Don't know if I could trust second hand ones, unless from someone I know.

**Update to update...
I tried the Trident slides first but it didn't like them - And the pulsing was still there!!!
I returned the Trident carbs to original then fitted those - it wouldn't start... not a fart.
I pinched the choke assemblies (coz they're in much better condition) and diaphragms from the Trident carbs and fitted them in my original carbs -
NOW IT WON'T FEKKIN START!!
I've checked the coil connections etc. so it looks like more fun and games tomorrow

** Update to update to update 
I hooked up the ignition tester once again to find that everything was as it should be.. After much head scratching and swearing I fitted my spare battery and gave it one last crank - it coughed feebly, then suddenly burst into life! at about 6,000 rpm.  I tried to turn the idle down but it wouldn't run any slower, I shut it off and I began to take the carb lids off and then noticed that the throttle balance screws looked a bit 'high' and on checking I found that I hadn't adjusted the cable properly  wot a tit!  So now, after replacing the diaphragms and choke assemblies with the ones from the Trident carbs, it runs OK.... AND the pulsing has not completely gone but is reduced to a slight bit at 1500 rpm, which I feel can probably be tweeked out with either balancing and/or mixture adjustment..... HAPPY FEKKIN DAYS!!! 
I think the failure to start with the Trident carbs could have been due to the same reason, and now I'm so good at removing and replacing the carbs I may just feel the urge to try them again - at some later date - but for now

goes to show their are some trust worthy strangers out there 
glad to be of assistance 
if you hadn't thought of it already try using shell vpower
made a lot of difference to the slow running of both my trident and my 955i tiger
happy days

Thanks Vince, the only reason I went for yours was that this forum is the one place where I know I can trust people -
I've never found a nicer collection of oxygen, carbon, hydrogen, nitrogen, calcium, phosphorus, potassium, sulphur, sodium, chlorine, and magnesium [plus <1% trace elements] 
(and the price was right  :icon_wink:)
