Carb ajustment

[SchOX]

Hi

I'm sure this question has been answered a million times already, but since I don't know the name of the parts/components, I do not know what to search for...

There are one screw on the bottom of each carb that has to be ajusted (see image) - I believe that you should screw them all the way inn, and then ajust in by turning a spessified number of turns out.

How many turns?



Some data witch may or may not influence the ajustment:
California 1100 without the california extra's connected.
Stock jet's
K&N airfilter - with "stock setting" restrictor (I'f it is usefull, I can put in the performance restrictor)
Aftermarket 4-2-1 performance exhaust
Stock ignition

I know that this probably doesn't help too much in your current quest, but I don't see the image you're referring to.

That is a tough one to answer. You have a K&N with a after market exhaust. Right there tells me you are running on the lean side. All I can say is get a jet kit and follow the instructions. If you ditch either modification, you still need to re-jet. If you go back to complete stock, factory exhaust and air box, you will be fine. Unless there is a difference with the 1100's.

Do you see it now? - post edited, I do not know where the image had gone..

OK, will get new jet's (I'm waiting for some that a member on KR offered to send me at convenience) - but how do I adjust until new jet's arrive?

Stock exhaust and stock air filter is not an option atm.

those screws are the idle mixture screws, past 1800 rpm they serve no purpose.
Do you have a problem with the bike idiling?

if that picture is your carbs, someone has been in them as the screws are plugged from the factory for california bikes

More Importantly
how does the bike run?
what does it do and at what rpm does it do it?
what do your spark plugs look like?
are the carbs stock?, how do you know?
what is the number of the main jets ?
what is the number of the needles?
what air pilot jets does it have?
all of these could have the right numbers, but could of been drilled out!!!!
have they been sycronized ?

OK, what setting shall the idle mixture screws be set?

The carbs has been fitted with new gaskets and new needle valves (it overflowed).
The bike does not run cause the carbs are not mounted - syncronizing will be done after the carbs are back on the bike - I just need the basic setting on those idle mix screws before i sync the carbs.

The carb's are stock 92 california 1100f carbs - stock main jets, stock needles, stock air pilot jets.

(The reason for K&N airfilter is difficulty getting hold of a stock, the reason for the aftermarket exhaust is rust on the original - so stock is not an option atm.)

It's my carbs, and someone has been in them (previous owner, I suppose).

Since I now know the name of the screw (air mixture screw) I did some searching here, but only find settings for 600 and 750, but both are recommended at 2 1/2 turns - can I start with this setting, and increase if it backfires on slowing down?

[ThAzKat]

OK, same carbs as the pre750! 2 1/2 turns is a good starting point. unless you have a dyno the air filter will be a bit of a battle to tune the carbs.
all you really need to do it go 2 sizes up on the main jets! I reccomend setting the floats at 14mm to start.

The dude is also in Norway. Aren't their carbs set different?
Just did some research. 2.5 turns out. Thaz nailed it.

I'm in Norway - witch other dude is in Norway?
The European GSX1100F might be set up differently, but my Kat is not a European F, it's a US/Cali Kat.

2,5 turns set up, ready for sync.

there was three setup for our bikes
california
rest of us
UK and canada.

Guess what setup had least performance? yep you guessed the Californias (strict emissions).
The Uk and Canada bikes had the best and where quicker, You should change the jets and needles to that spec (i have that breakdown somewhere).

Your bike will really wake up once you do that especially if you have the 4 into 1.

Yepp, I know (about the cali being the laziest in the family) - I think I'll go for a factory pro jet kit for next season.

[ThAzKat]

Factory Pro is a good choice!!
