Hello, all. Any history on this bike of throttles sticking open or
opening spontaneously?

So, what's the deal with MotorCycle Newsgroups? Does it cross post this
query to every MC-oriented NG on the web?

You've crashed it, and you're looking for someon to blame, right?
And AFAIK *no* motorcycle throttle can open spontaneously.

I have not heard of any motorcycle make or model having a tendency to do
either things.
Spontaneously open? I suppose if a bellcrank were loose on the carb
shafts. That sort of problem would be easily identifiable.
Sticking? If there was a mechanical failure or cables were misrouted, etc.
Come to think of it, if a mechanically inexperienced person were to drive a
motorcycle that did have the bellcrank loose on the throttle shaft, they
might use a description very similar to what you just used.

FWIW: Long story, you may not want to read it. I bought another Honda
MT250 this spring with the intent of getting it on the street. After a
quick and dirty rebuild I was having trouble getting it to idle.
MTs have a funny idle circuit. They use a huge jet and have a mixture
screw with a hole in the middle of it. It is kind of like a banjo
fitting in that even with the screw all the way in, the hole makes it so
it is still open.
The mixture screw on the MT was completely corroded in. I ended up
having to drill it out. I didn't have an exact replacement, so I just
scavaged one w/o the hole in it off another carb.
So with the wrong screw the new MT didn't idle worth beans, not a lot of
throttle response down low, that kind of stuff. Thinking maybe I was
loving the pooch with my rebuild I switched the carb over to my 'good'
MT to see if it displayed the same symptoms.
Sure enough, same symptons on the same model but a different bike. I
ended up screwing the idle screw all the way in/max opening. It would
still die after 5-10 secs with the throttle off.
So I decides to maybe it just needs to be wrung out a bit to clear any
gunk left in it. As I am starting it I notice the over flow is over
flowing, the rebuild kit hadn't got here yet, so I shut off the petcock
while I am kicking it over. The puppy starts, I shut off the
choke/enrichment lever, and take off down the road for a couple of WOT
roll off throttle cycles.
Notice I didn't say I turned the petcock back on. That is because I
didn't turn the petcock back on. Turned out at idle it was running so
rich it was killing the engine. Soon as the float bowl emptied a bit and
leaned out the carburation it was suddenly trying to idle at ~6,000
RPMs. I crashed so hard my dead relatives felt it.
Punch line is There is at least one other senario where you can get an
engine that to the casual observer would seem like a spontaneous
throttle opening.
Anyway, I agree I haven't seen a throttle spontaneously open. I think
there was one time where I had a throttle cable got hooked on something
and everytime I made a left hand turn it pulled the throttle open, but I
wouldn't call that spontaneous.

Sticking throttles? You *are* joking? I've known loads of cases.

But have you heard of a particular model that did it on a consistent basis?
I have not heard of a particular model that had a recurring problem like
that.

Name one specific model where there is or was a known problem of having a
sticking throttle.
No bike manufacturer could afford for this to happen, they would be sued out
of business.

I was thinking of loads of antique shit I've owned in the past, where
sticking throttles could be due to cables that frayed prematurely,
utterly crap throttle grip housings, inadequate carb return springs etc.
However, I admit these were, as I say, in the past.
But then, much more recently, there were devices delibrately designed to
make them stick - throttle adjustment screws. Old airhead BMWs had them,
as did a Guzzi I once owned. A friction screw that bore on the twistgrip
tube. And a US company called Vanda-Cruise even marketed an aftermarket
device that did the same, as a "cruise control"

See above. I'm not sure if these devices still exist, but that doesn't
alter the fact that they did and there are plenty of bikes equipped with
them still on the road. You don't know enough about motorcycles, really,
do you?

You are really clueless. You offer old antique bikes, really one offs, as
"proof" to back your bogus claims. Then you start to mention poor
maintenance habits as proof, when the orginal post was questioning wether
sticking throttle problems exist on newer bikes. You even "cliped" the post
so someone just begining to read this post has no idea what is being
discussed. What a loser.
As for after market devices, I'm sure the orginal poster was not discussing
this either. Quit twisting everyones words around. All your doing is making
a complete ass of yourself.
I've forgotten more about motorcycles than you will ever know.
I'm begining to think all you do all day is troll for attention as you
rarely have anything constructive to add to any discussion.

The bikes I referred to are hardly antiques. BMW a nd Guzzi werefitting
friction adjusters to its machines well into the 1980s, and quite
possibly beyond.

I'm not twisting words around. I merely mentioned earlier that I had
never heard of a throttle self-opening, but knew lots of instances of
sticking throttles. The original poster never mentioned maintenance
problems, and they are probably the leading cause of sticking
throttles.

That is evident. Shame you never renewed the knowledge. The examples I
have posted are entirely valid and in context. You're just peeved
because you didn't think of them. Or anything else.

Well, as you've come from another thread to this one, to post your

Motorcycles generally *do* have a greater tendancy toward loss of
throttle control and sudden acceleration than cars have. Many
possibilities include problems with the cables, cable rigging, and old
slide valve carbs used to warp when the mechanic tightened the nuts
holding the carb to the cylinder head and the throttle would stick.
Also, when the motorbike is laying on its side after a crash, gasoline
can get dumped into the venturi by gravity and the engine screams at
high RPM until the rider (or a bystander) operates the key or
killswitch.
This is what happened to Gerard, the original poster, it's why he
wanted to know about sudden accleration:

My point exactly. Others posted there were many bikes that have sticking
throttle problems right out of the box.
Gerard bought a used bike of dubious background. Being a novice rider, he
should have had a friend or taken the bike to some shop to have it inspected
prior to riding it, paying real close attention to safety items (brakes,
kill switches, lights, smooth throttle operation, including turning the
handle bars full turn in both directions, etc.).
Anyone who does any maintenance on motorcycles learns fairly quickly taking
things apart is easy. It's putting things back together correctly that is
the hard part. I suspect Gerhard's bike just had some work done on it that
involved either the replacement of the throttle cable(s) or the fuel tank
was removed and the routing of the cable(s) was affected.
Be safe out there.
Just my 2 cents.
Tom

No, they didn't. Why do you post deliberate untruths? Why bother to lie
when the earlier postings are there?
Let's just review what I posted, in answer to another assertion. Here
we go:

I have not heard of any motorcycle make or model having a tendency to
do
either things.
Sticking throttles? You *are* joking? I've known loads of cases.

All you have managed to do is make yourself look an unpleasant
objectionable little creature who has not the wit to admit when he's in
error.
You see, I simply said I've known loads of instances where bike
throttles can stick, and cited poor maintenance, bikes whose throttles
are/were deliberate designed to stick, and even an after-market gadget
designed to make them stick.
Now, somehow you interpreted this as meaning I was claiming that loads
of bikes behaved that way "right out of the box" (your phrase) when, as
anyone else reading this thread can see, I made no such assertion. OK,
maybe you didn't read the posting properly, But you certainly jumped to
an incorrect conclusion.
As ever on usenet - when you screw up, best to fess up, and stop digging
a deeper hole. Had you said: "Oh, I thought you were referring to modern
bikes that had these faults built in, and now I see you weren't..."
nobody would think any the worse of you.
But you didn't.
