so i am removing my carbies because i have fuel economy that is 35km worse off per a tank, and fuel that drips from the small pipe (tank end) out next to my oil filter. so while cleaning my carbies, pulled the big pipe off that connects the two carbies - and it look pretty clogged up with a bunch of 'gunk' as per photos: Other than that - anything else we should be cleaning while in here? The floats move freely and all looks good from that aspect Thanks

I had the same sort of thing when I removed the carb heater hoses for the first time.
I removed the carbs and gave them a complete clean up from top to bottom, then did a carb sync and idle drop as per the manual, then I reset the TPS and all was well. Being anal as I am I replaced the air filter and did the Burnie Morgan mod and all was well, mileage went up and performance improved.
Have you checked the float height ? Does the bike have holes drilled in the slides .
P.S When remove the carbs completely undo the bracket that holds the choke knob and remove choke cables as an assembly with the carbs as there is less chance of breaking the flimsy plastic choke fittings on the carbs.mWhile you are in there look to see if there are any restrictors in the inlet rubbers and remove them with a pair of pliers. Good luck mate, these carbs are finicky, get them right and they are a joy, stuff it up and it is a nightmare, trust me I know by learning the hard way.

So those are heater hoses...right so not overly concerning in the scheme of things. How do you get the throttle cables off? They are annoying. So to clean the carbies just pull all the Jets out etc, clean and reassemble? When it comes to balancing the carbs could it be done by myself? I am no slouch at building bikes just never balanced carbs before :-(

Do a search on here for carb sync and all the info you need is there.
I have remote vacuuam lines fitted and a good set of calibrated gauges . I know when my bike is out as it starts to vibrate at about 4 - 4500 revs in top gear. All bikes are different but you can feel it when things aren't right. Throttle Position Sensor should also be checked whenever you sync the carbs.
It would be a good idea to download the genuine Honda manual as there is a section in there about Carb Sync and idle drop procedure that is very good. Time consuming but worth it. Just take your time, and the more you do it the easier it becomes.
As far as the throttle cables go they are a pain, once again practice makes it easy, just slacken the lock nuts off, remove the cables from the holder and rotate the throttle until you can remove the cable ends. When you refit them do the same in the reverse . ( I hope that makes sense )
