I've read this thread a number of times.
I have a Jardine exhaust on currently and bought a jetset as well as a uni filter from Lancer that should be here later this week.. so as i'm getting familiar with carb tuning i've been reading and doing some research.
From what it sounds like below it's pretty simple and straight forward, i just want to confirm some questions.
1 - idle speed"if you can get the smoothest/highest idle speed by setting the idle mix screw between 1 and 3 turns out from closed"
question 1 - idle mix screw - is he speaking of the idle screw? or the fuel/air mix screw?
question 2 - do i just need a decent high idle that's steady and not surging?
question 3 - i do this after the bike has warmed, correct?
i'm also guessing i can reference this thread

3 - needle tuning" if you get some acceleration, set your needle up a notch, or reduce the spacer..."
question - do these needles have a few notches in them to place a washer? i was thinking these carbs ONLY had the white spacer?
Are there some other good threads that i might be missing? i just do'nt want to go lean and blow up my engine.

General, seat of pants tuning...
Idle speed...
Set your idle speed with knurled screw on the left side, near the enrichment knob... Set it to be smooth and steady,... not loping or stumbling, (this ain't a Harley, don't try to make it sound like one).. (a slow loping idle is very bad for your engine)...
Idle mix... and pilot jet...
If you can get the smoothest/ highest idle speed, by setting the idle mix screw between 1 and 3 turns out from closed,... you have set your idle mix, and your pilot jet is the right size... (if you have to go more than 3 turns out,.. go up one step on pilot jet)..(if it seems to make very little difference turning the screw, you are probably rich on the pilot, and can go down a step)...
Main jet...
To test the main, accelerate from 30 or 40 mph, in 4th or 5th gear at full throttle for several seconds, then reduce throttle by about 1/8,...if power increases for a second, you are lean on the main jet. Go up one jet size and test again.
Needle jet...
If your main is good, and your pilot is good,... but you have surging at steady low speed... try pulling out the enrichment knob, one notch (do this with a fully warmed up engine)... if you get some acceleration, set your needle up a notch, or reduce the spacer...
... if it bogs instead of accelerating,.. you are either rich, or good... increase the spacer, or set the needle down a notch, until surging goes away, but you still get some bogging with the enrichment valve pulled out a notch...
