What year of yp400T? V? X?, mines a 2005, and idles as bad as the
2003 skyliner 400, same bike same problem, but they said they counter
weighted with a new crankshaft after the Yamy 2004 Twin generated strange
error codes at the time...

Single 4stroks of UNDER 25cc that Idle around 1,100rpm, SCOOTERS???.
if the motor is used in an inverter for instance, then it can idle at
800rpms, but a lawn mower will stall at 800rpms....

 

That's just *one* example. I've had four-stroke singles that idled quite
happily at 1000rpm or thereabouts.

What does this paragraph mean, exactly? Wtf is a Vino 1500cc when it's
at home? Two bottles of red wine?

 

But you said it was about four-stroke single engines?

There weren't many four-stroke scooters around 30 years ago. Time for
your meds, I think.

 

Where has anyone denied that this one bike has a stalling problem? Feel
free to point it out.

It's just that some of us think you're an illiterate fuckwit with a
Henry-like obsession.

 

Pot or kettle?

 

Nah! Piggy's Clown is a psychologically disturbed Gulf War vet who
*wishes* he was a Limey, or a Mongol, or a hobbit, or anything besides
the emotional mess he really is.

 

Yes, and they are *very* idle. They haven't run in years and are
covered with spider webs in the garage.

 

I believe lots of multi-cylinder bike engines are recommended to idle
at 1400+rpm, such as a CB750 (not to mention lawn-mowers and
chainsaws!). I had wondered if part of the reason had to do with
carburetion, perhaps easier to adjust multiple jets on each carb. But
I see that fuel-injected 400cc scoots like the Majesty and Burgman
have similar idle speeds. If modern injected bikes have similar idle
speeds then maybe my guess was bunk. For sure, most bike engines can
be made to idle slower, but I can guess that when a CVT drive (no
manual clutch) is involved, a higher idle speed will involve less
start-up automatic clutch-lag. But I suppose similar reasons would
apply to clutched bikes, the engines are usually much smaller than
those in cars, don't have much torque below 2000 rpm so could stall
more easily than a car when the clutch is engaged, so maybe it's all
about rideability/safety.


The only thing I know of that seems special about thumpers is that
some of the larger ones need a decompression gizmo in order to start
when cold.


Interested to hear comments.

 

....

It seems even a 400cc Suzuki Burgman has a 'decomp cam'.

 

Idle speed sometimes depends upon cam timing and valve lift. Some hot-
rodded I-4's need to idle as high as 1800 RPM to keep from stalling.

RPM is an average, it's not consistent.

Setting the idle up from the typical 1100~1200 RPM will quiet down the
cam chain which is under considerable difficulty as the revolution
speed of the individual stokes actually does vary.

My KLR600 has an automatic exhaust valve lifter which will engage and
stall the engine with a loud CLACK! if the idle RPM drops below about
1300 RPM

 

You believe wrong.

Yes, I think my memory was bad, could have been something just over
1000 rpm for an '82.

Thanks, those are much more obvious reasons than the ones I thought of.

 

Typical Piggy troll...

 

From a haphazard scan of Clymer Motorcycle Data, years 1988-2000, it
looks like there are only a few above 1200+/- 100 rpm, and fewer at
1400, such as the California model of CBR600, a few 650 Suzukis, BMW
650, so mostly thumpers and all carbureted. The FI models of the same
bike have idles 100 or 200 rpm lower. (Ignoring the larger CVT scoots
which are all 1400 or more.) Below 350cc there are many thumpers with
high idle rpm's, some as much as 1900rpm, which agrees with the small
flywheel reason, although I guess some people would call them sewing
machines, not thumpers.

 

Nope. Just fact. One of my fours has a recommended idle speed of 950rpm,
as it happens.

 

Thank you. Dear old Krusty can't get anything right.

I guess another reason for higher idle speeds than cars could be to do
with the relatively weaker charging systems on bikes, smallish
alternators turning at crank speed usually.

 

Actually you juvinile junkie...your fantasies and desire for man flesh
isn't my problem. Not to mention your weak chickenhawk style was more
appropriate in the late 60's.

Right, my *boob* I meant 1500rpms-->1650rpms after break-in.....
