Automatic choke? You tell me...

Automatic choke? You tell me...

I'm getting back in the saddle on this NG again and have a weird thing
about my bike that I'd like some insight on.

2005 Honda 750 Aero Shadow; single carb with pull choke on the side.

To take off in the morning, I'd pull out the choke and warm up this
cold-natured beast before taking off, turn the choke off and *chug*
away for the first mile or so until she warmed up enough not to
sputter.

Lately, however, I've taken to pulling on the choke, start her up, and
just take off. Works great like that; much better than letting her
warm up and turning off the choke and then taking off.

So, when I take off, I fully expected to have to push the choke back
in down the road only the choke is already back in and the bike is
warmed up.

I thought I might be alone, so I mentioned this in a Yahoo listserv on
my bike and someone else came back with the same story.

So, now I assume that the choke assembly has a vacuum such that as the
engine warms up, the choke knob is retracted to the closed position...
yes/no? Maybe this the way all bikes work and me coming from riding in
the 70's, just didn't know it.

Ideas?

Thanks,
Greg

Not to sound like a smartass, but . . .

If it works the way you say it does, that should be outlined in the owner's
manual. In any case, the owner's manual should specify how to use the
choke. -Dave

It's not in the owner's manual and for good reason itseems... someone
who knows just told me that the retaining nut for the choke cable is
loose, allowing the vacuum in the engine to pull the knob shut. Any
looser and I may lose control over the choke knob,

Darn it. I thought mebbe Honda had engineered a little something into
these bikes.

I'll fix it tonight. All these little checks on cables, screws/bolts/
nuts, tire pressure, brake pedal travel... geezsch, I just wanna ride;
not do preflight checks :)-

Not to sound like a smart-ass (yeah, right), but what you are
describing is just one more set of reasons I don't care for Honda
cruisers.

Fuel injection solves the choke problem, a rear disk brake would
rarely need adjustment. V-Twins are known to vibrate causing stuff to
fall off....

My Nighthawk 750 had a manual choke, I always rode off with the choke
on and then turned off after a few minutes of riding.

Oh yeah, don't forget to adjust that chain.

Yup and to get that with a Honda cruiser, you need to buy their big
dog VTX1800 while other makers use FI in smaller bikes.

> a rear disk brake would rarely need adjustment.

Again, requries upgrading to nearly their top of the line, while other
makers have this as stock equipment on smaller bikes, IIRC.

> V-Twins are known to vibrate causing stuff to

I'm finding that out big-time; seems this use of a single crankpin for
that "traditional V-twin feel" is one of the culprits, but to get a
dual crankpin design, you have to buy either the 1100 Sabre or
1300VTX; can't remember which one. It's funny; on the one hand, the
single crankpin is extolled as a feature for a true VTwin ride and for
another model, the dual crankpin design is extolled as a feature for a
smoother ride. I'll opt for the smoother ride next time.

That's what I'll do after I tighten up the retaining screw tonight.

Well, there's one good thing about my bike; it's got shaft-drive, if
you don't mind a little jacking that goes along with it.

I'm really not bad-mouthing the Aero; it's a decent bike that I got at
a good price with hardly any miles; totally like new condition; only a
year old. It's just that after you spend time with a product, you
start to learn its faults and when you compare it with superior
products, you see what you're missing.

Good to see you back Greg... also glad to see this post because my ACE is
doing the exact same thing as you described. Let me know where that
bolt/screw is so that I can take care of mine too! I'm not around my bike
right now to look...

Geraldine's is beneath the knob on the dash. What looks like a
cosmetic grommet is actually a knurled soft rubber nut that screws
down with finger pressure. You can adjust the drag on the choke cable
with it. Unscrew it all the way to see how it works. Inside there's
a split bushing like the driver end of the handle to a jewelers'
screwdriver set.

I read the post about the rubber nut, but I'm not sure if this is it.
Mine is setup as follows form the choke knob to the enginge housing...

1. Choke knob
2. choke cable
3. fairly large rubber covering over something
4. the closest I can come to is a barrel nut (that's not what it is),
but it seems like it could be tightened, but it is tight already

Is there a nut underneath that rubber covering? Is that what you are
referring to?

This is from Geraldine's Honda Shop Manual:

"Adjust choke control tension so the knob will remain wherever it is
positioned, but can be moved without excessive force.

"Turn the adjuster clockwise to increase tension or counterclockwise
to decrease tension."

That's just so you know. :-)

Ok, thanks. That looks a whole lot different than the choke assembly
on ym bike, though. Hmmm, maybe I should look at the tech manual for
my bike, eh? Right now, it's keeping papers form blowing away in the
garage <g>
