Suzuki GZ250 Marauder:
very difficult to start in Cold weather -- anything around under 8
degrees C,
what exactly do carb Heaters do? and would they go any way toward
solving this problem?
also is there such a thing as an Air Intake heater? and could this
be a factor to consider - if the air was warm on the intake during
starting~ wonder if this could solve it - I'll test this out - ha~ but
if it does.. how the heck could I set up some kinda air heater at the
intake!? and with a switch on handle-bar.
Otherwise it's running good! Just cold cold starting is difficult,
often taking 5 or 6 attempts! each attempt consisting of several
engine turnovers, with a decent pause between.
Sometimes feel the engine "starting to turn over" but not really
firing up - and soon as you release the starter it stops. Eventually
starting - but!!!@#$!!!! annoyingly difficult.

They stop carb icing, which isn't really a problem at 8C. Though in
damp weather it can affect bikes in temperatures slightly above
freezing.

Don't bother. The answer's still no.

Try a new plug and a service.

Hold the clutch in
Be sure you have 5W-30 oil in the engine
Make sure the battery is fully charged and full amperage capacity.
Engage the choke if it has one
Hold the throttle open about 5% over fully closed.
8C is not cold
Minus 20C is getting cold. Wink

Duh. The subject is "Cold weather" and posted in late June.

Bullshit.

Bad idea. The temp stated might be the lowest he rides at, in which case
5W30 is NOT recommended. Besides that, many 5WXX oils are "energy
conserving" and may be harmful to wet clutches.

> Hold the throttle open about 5% over fully closed.

Wrong. Best to leave the throttle CLOSED, not only initially but until the
"choke" is nearly "open".

These bike are not known for cold starting problems (I have one).
Sounds to me like improper technique, including maybe not letting the
starter run long enough.

Buy an AGM battery. Westco or Yuasa, doesn't matter.

Having up to an extra 50% CCA that an AGM battery will supply combined
with the battery surviving winters WITHOUT futzing with a trickle
charger makes all the difference in the world.

Oh, and 8C is not cold. That is t-shirt weather.

Bullshit. A KLR650 has *never* had a choke.

Boy, are you a work of art. You pull out a fiche from bikebandit and
call that evidence? Wow.
Try looking at Kawasaki's Owner Manual, page 12. Item 10 says it's the
choke. Page 35, Starting the Engine, says, "If the engine is cold,
push the choke lever all the way to the left," and it shows a picture
with an arrow pointing to it.
The Kawasaki Motorcyle Service Manual, section 12-3 tells you how to
adjust the choke, with illustrations.
The Kawasaki Motorcycle Service Manual Supplement, section 1-10, shows
the routing of the choke cable.

You should let Kawasaki know they're so wrong.

This is one of Krusty Kritter's favorite hobby-horses. You're not going
to dissuade him from riding it by pointing out that Kawasaki uses the
word "choke", as many of us do, to refer to the "enrichener" device.

Hi..
er.. is it safe to step back in for a sec or two~
jeeez ~~~ I didn't mean to start a debate! Smile

but to clear a couple of things up
riding temperature -like in the here and now , I go out in all weather
and all temperatures,
yesterday and the day before it was down around zero celcius
( I specify Celcius in case anyone's visiting here from a farhenheit
country)
The cars in the caspark were covered in heavy Frost, is was a chiller
of a morning!!

yep the GZ250 has a Choke~ or what did others refer to it as? --
starter-enricher? !?
anyway it's got one I Can confirm that.

the basic problem is on these freeezer mornings/nights it takes
several attempts to start,
unless I can somehow keep the bike in a warm environment - which isnt
always possible.

the temp Did go up this morning (29th) , but regardless of,- I think
about 6c, I did gave it some extra warm air blast toward the air
intake on ignition start - it'll take another test or two on other
mornings that are colder - but it DID start up good on only a couple
of revolutions - which it has not done recently.
whether that was coincidence or what ~ I dunno. maybe it's a dumb
thought to think this would make any difference - I'll test again next
time there's ice on the grass.
But Thanks for the advice so far injected here - I'll read again and
see what can be done to improve things,
and for a Suzi GZ250, almost 7 yrs old, it goes great! it runs like a
small rocket otherwise! If it'd start without the slightest
hesitation in the Cold, it'd be perfect! (as perfect as a 250 can be
anyway Smile )

Oh yes, they do. Some of them. FI isn't universal yet, not by a long
way.

And no, I'm not thinking of "starting enricheners" or whatever you want
to call them.

That "whatever you want to call them" has been used on many models of
motorcycle since the 1970's.

This is mostly a question of semantics. Most modern motorcycle carbs (at
least for the last 20 yrs. or so) have used an enrichening circuit in the
carb, rather than the old traditional "choke" that closes the throttle plates.
Technically, it could be said that these bikes no longer have a choke, but
most of the bikes I've owned over the years still had the enrichening lever
labelled "choke" and referred to the enrichening system as "choke" in the
operators manual.

Balderdash.

If all your friends jumped off a cliff, would you follow?

Choke: to reduce the air intake of (a carburetor), thereby enriching the fuel
mixture.

My KLR does NOT have a choke.
