I was wondering if someone could tell me how much I am going to paying
(ballpark of course) if I take my bike into the honda dealership to get
my carbs cleaned. What should I expect once I have this done
(performance wise).

Thank you for your help,

300 bucks US is typical for 4 carbs.

The performance difference would depend entirely on information you
haven't provided. How's it running now?

Pulling off the carbs and cleaning them with several cans of gumout might do it
for you, and it is not a horrible amount of work.

If you haven't tried just draining the fuel from the float bowls even that
might get rid of your problem.

Rocky is sayin' what I woulda said about the Gumout.

Something else you may wanna do is dump about a half a can of that
carb/fuel injector cleaner stuff into a fresh tank of hi-test. Then run
that little beauty down the road for an hour or so.
That outta help some. :)

Hi moto,
You will have to excuse me. I am far from being mechanically
knowledgeable, but I am trying to learn. You are saying I should spray
about half a can of carburetor cleaner into a fresh tank of gas, right?
I do have some carburetor cleaner (B12 can ~16oz) sitting in my garage
that I used to use for one of my older cars. Is this something I can
use? Or should I use that Gumout you were speaking of. Unless I have
someone with me to help me, I am going to stay away from doing anything
which involves me having to physically mess with the carbs. I know I
will screw something up :-), but if there is something I can try with
cleaners which work through the fuel, that is something worth trying.
Again, thanks for all the information.

One product that a lot of people have had luck with is called Sea Foam.
It's available at NAPA and several other places. 1/2 can poured into
a full tank can clean out your carbs if they're not too gummed up.

I've got some sitting in both my '92 Nighthawk and my Concours. My NH has been
running progressively worse each spring but tank additive carb cleaners
administered in the spring would take care of it till the last two summers.
Disassembling the carbs to spray cleaner through them last winter really didn't
do much. I'm hoping a winter of soaking will help it out.

Hopefully Dave (and I) will be lucky enough to have a tank additive solve his
problems.

I don't know what moto was saying, but My suggestion would be to use
Techron fuel system cleaner in a tank full of fresh gasoline. Add as
much Techron as the bottle says for the amount of gasoline in your
tank.

It is worth trying. I've found Techron to be pretty good stuff for
cleaning and keeping carbies and injectors clean. It might not do
enough good that the carbs won't need to be pulled and cleaned, but it
might, and if it does, it saves a LOT of work.

If you're near Rochester MN, I'd be happy to help; with all this snow
I'm not motorcycling anywhere anyway . . . .

Don Fearn recommended Techron fuel system cleaner. That's good stuff,
and pretty much what I had in mind for you to use.
BTW, there's a Big diff between carb cleaner and fuel system cleaner.

I think Rocky was tryin' to save you some time and money by having you
blow out the carbs jets. If you don't know how to do it, I kinda think
there's gonna be someone here that's near you to give you a hand.

If I was, I would.
good luck

So it seems like the consensus is to try some type of carburetor
cleaner that is added to the fuel. I will definitely try this. I just
have to decide weather to use SeaForm or Techron. Thanks to all of you
for all the information. It was very helpful. Hopefully this will help
my bike with the hesitation in first gear. I really did not want to
spend 300-500 to have my carburetors worked on.
Thanks again,

Thanks for the information. Well, the only thing that made me think it
needs to be done was because first gear is not as smooth as it used to
be. It is sortof rough on the acceleration. It is hard to explain, but
maybe you can extract something useful out of that poor description I
gave. What type of things would you look for normally that indicate you
need your carbs cleaned?

Thanks!

Has the bike been sitting for 3 or more months without being ridden? If
yes, then you need your carbs cleaned.

If you've been riding it consistently, it's something else.
