Indeed it the same if you can do carbs you'll be fine.
Sounds like the throttle bodies have been over adjusted(and are set to high) so bringing them all down should bring the fast idle adjust back into use.
Take your time and you'll be ok
Good luck buddy  :cheers:

#1 in the attached pic is for syncing 1/2 with 3/4.
#2 is for fast idle. Don't touch this until after you have done everything else (see above posts of Seth and Northern). I would start with cleaning all the connectors first with contact cleaner. EDIT: just read the last posts. Synching might be all you need to do.

Here you can see what makes the "little wheel" move: https://www.youtube.com/watch?v=AhMkXCFyv6I&feature=youtu.be

Great info @Andre
This should be made a sticky or something( @gsxbarmy @VladTepes ) as its so very useful to know where the adjusters are(I've never adjusted mine so wasn't totally sure).
We'll found buddy hope this helps @Simonic

Many Thanks to you both Seth and Andre.
The video was especially interesting.
The little wheel is in fact in line with the operating cam so this would suggest the the trottle bodies are indeed over adjusted on the offside bank.
I'll report back when i've had done the synchro.

Thank You again gentlemen

BTW, my fast idle problem was solved after I re-re-cleaned connectors. First cleans were done with WD40, last one with contact cleaner :stir:

@VladTepes
Nothing to do.............all day to do it....I love retirement :lol:

@gsxbarmy
Sorry i ment just the picture of the adjusters I know this is a sticky thread.
It will save time when folk come asking for this very thing .
Thanks for the reply buddy .

@seth I put in a couple pics in Fuelling / Re: Synchronize your Throttle Valves. I think they belong there.

Cheers buddy between what @gsxbarmy had already done and your added pictures there is everything in one place .
Top job  :onya:

Reporting back....
I've managed to synch the throttle bodies ok.
The rhs was doing al the work and in addition to that the difference between 1+2 was huge. it really looks like someone had just been trying to make some adjustments without knowing what they were doing.
The bike is running much better now.
The fast idle still is not working but i can get the bike started ok.
This is a job foar another day.

I'd like to thank all you guys who have offered advice. Much appreciated  :cheers: :cheers:

I know this is an old thread, but did you get the fast idle sorted out? I have a mate that has the same problem, TPS and STPS are just about spot on, but when measuring the voltage as mentioned in another post, adjusting the fast idle screw makes no change to the voltage, the resistance of STVS is correct as are all other sensors...bit of a strange one, bike runs and pulls really well apart from this.

Might be worth checking if the cam wheel is actualy on the cam... found mine was not seated on the fast idle cam.

You can have all the correct measurements on all sensors but if there is nothing to engage the high idle to... well... you feel kinda stupid when you remove your old throttle bodies to replace them with a new bank  :doh:

Checked the roller was seated all okay, just starting to wonder if the throttle adjustment is way off and contributing to this problem. Going to get the bike over to my place and have a check through, at least I'll be able to compare it to mine  ;)

Hi guys. I have a very stupid question. Where is the secondary throttle valve and how can open or close it by a finger?
