Suzuki Bandit GSF 1200 N - Basic Air Fuel Ratio Setup (HD)

So after cleaning and assembling the carbs back, there was another issue, the engine was hasitating to go into higher revs. Obviously it had a problem with the air fuel mixture setup, too lean or too rich. So we're going to do a very basic setup of the carbs regarding air/fuel mixture on this 4 cylinder engine.
TOOLS
- thermometer optional
- angled screw driver to access the carbs idle screw, for example:

Wow! Just the video that I needed. Thank you so much, it is so well explained and so clear. It’s the only video that I found explaining this. Thank you so much!

[@REBUILDLab]

Yes it is, glad it helped and served!

[@Will-dm1pv]

Just a heads up,did you notice the arc across number three possibly three and four plug leads to the head gasket breather,approximately 5.56 timestamp.
Didnt seem to effect the running of the bike tho.

[@REBUILDLab]

Must say that originally not, as I was focused on the setup...now as you mention it, yes there was an arc, which is not good. Must think about changing the leads. Occasional missfiring does not have much effect on the engine behaviour - it looks like it. I tested the motorbike for top speed and the cylinder is working.

@@REBUILDLab I have an 99 1200,carbs balanced,AF ok. problem,on slow deceleration(even at 40mph)worse the slower it gets,revs off,bike has a judder/jerky issue,not enjoyable to ride,any idea the cause?

[@REBUILDLab]

Still an AF problem if spark is good, I think. Is it doing that at still stand too on a free decelaration? I would pin a small diameter transparent hose to the carb drainage outlet and watch what the fuel level height is doing. If the engine idles good, then the idle jet should be ok. Then a clogged carb bypass to higher loads could cause this eventually, you could see that bypass in the drawing on the video. The engine doesn't receive enogh fuel mixture or receives wrong mixture... That's what I think at least...
