There is a scan of the manual, I have a copy somewhere, when I find it
I’ll send the pages that you want. Think the scan document was linked
off this site somewhere

Subject: [suzuki250fours] Microfiche and Radiator Fan for GS250FW




Hi All,

Just wondering if anyone out there had a copy (or knew where I could
obtain one) of the Microfiche for a GS250FW.  I'm specifically after
the part that shows the fork assembly, but would love to see the whole
thing..

I'm also after a radiator fan, if anyone has one laying around and
would be willing to sell it - please let me know! :)


Thanks in advance,


Carl

Hi Anthony,
I had a reply from you a long time ago about my GS250 not wanting to idle.
You said you had the same problem. Did you ever get an answer?
I finally got back to mine the other day - here's the deal....

It will not start cold except for using aerostart !!!!!
It then starts immediately and will run under FULL choke until warmed up
Gradually backing off choke and watching revs, it will finally run at about
2000-3000 - no choke.
It is rideable under these conditions and seems to restart while warm
without too much trouble.
Once started it runs well - plenty of power [slightly dead 7000-9000], seems
to be gtood except for the 2000-3000 lower limit [which soetimes becomes
4000].

I have checked float levels, slides, jets, all seem to be OK [then I'm not a
mechanic]. I even checked the diaphram on the fuel valve, thinking there may
be an airleak, not so.
The airbox had no filter or filter retaining items in it, I have not been
able to get an original so I manufactured a filter with aluminium strips and
airleaner foam [hoping this would be sufficient] - maybe this is my problem,
I have been told they are a bit fussy here [but I had a 250 Kwaka that
didn't care if it had an airbox or not].

At one stage I was going to replace the carbs and be done with it, but I
have not been able to come up with a pair that are in suitable condition.

So Anthony, or anyone else for that matter, I would be glad of any help you
can give.
As I said, once it is running - it goes very well, remembering the low rev
limit of 2000-3000.

But Anthony, I am particularly interested in what you found with yours.

Regards...
Garry Moylan

David,

These are rare bikes here in Australia and probably not worth much even in
great condition (probably less than $2000). For more details on the history
of these bikes see my web site, www.geocities.com/john_avis/suzuki

Regards,

John Avis

I am the proud owner of a GS250FW and know nothing about the bike.
Could anybody tell me anything about this bike and what it would be
worth if I restore it back to showroom condition.

I would apprieciate help from anybody

Thanks
David

Hello,


I have just bought a GS250FW and know nothing about it. Could you
please assist me in finding out a sort of value to the bike. What
did you sell yours for and what sort of prices do they go for? I
need to know if it is worth spending money on it to bring it back to
show room condition or if I will just use it as a run around.

I would apprieciate any help that I can get as this bike is so alien
to me.


Thanks for your time

David

Yeah...mine has 68,000ks on the clock and still runs like a watch!...no trouble
so far, but being a four, there's the usual complexity when eventually it's time
for an overhaul. That is more than made up for by the excellent handling and
brakes, + the performance!

Hi Everyone, I have just swapped my old car for this bike and have to
say I am quite impressed with it's performance. I have had a RGV 250
etc, and for a four stroke this goes really well. It needs a few
things Headlight, fairing blade etc to tidy it up. But is all road
legal still.
A bike mechanic friend says they are trouble- any thoughts?
Does anyone know a good source of parts.

Cheers

Hi Jim, I've been a member for about a year or so and have 2 GF250 bikes.I am
all ways on the look out for these bikes, as you know only a hand full was sent
to Australia.Can you tell me how much you are asking for it, the condition its
in and were you are located. I am in WA. Thanks and talk to you soon...

Hi Malcolm,

I'm after the fairing, headlight, mounting brackets and a front fender -
anyone around here got any spares?.  How much would you be willing to
take for the speedo?

The valve clearance check is pretty straight forward, though a little
time-consuming taking everything off (on a bike)..  If you need any
help, let me know!


Cheers,


Carl

Hi Carl

That is a good point. I will try this. I have had a lot of troubles following
the manual as it is unclear. Tommorow is a public holiday so I will get into the
garage and do my best.

I don't have the frame any more but I do have the spedo cluster and a fuel tanks
and the rear shocker. I think that is it.

I still have not done the float levels, as each time I tried I was uncertain
what eacactly to measure.

Thanks for the advice.

I will send you a couple of pics this week.

I suggest you do this to your motor if you're still having issues with it
revving out.


Also, do you still have the body of the GS250FW sitting around?  Or did

Hi Garry, if its the gf250s spec bike you have, the
gsxr250 carbs go straight on ie they are the same
inlet bores and the cables are the same too. I fitted
a set to mine and the only diff is they are jetted a
wee bit over but if your not concerned about fuel then
leave them in. Trust this helps, Craig.

Hi All,

Just a quick note to let you know that I have a GS250FW for sale -
Red, registered and runs beautifully.... Anyone interested or knows

Hi Malcom,

I got mine from the Suzuki dealer when I had an Across, though you can
also get it from here:

I wouldn't know about the ignitor, I'd be asking the wrecker about this.

Are you getting good spark?  Have you got the enricher (choke) connected
and working correctly?  Have you adjusted the pilot air jets (mixtures)?

Have you downloaded the workshop manual?

The float levels are measured from the carb-body surface (the majority of
the flat section under the carb-body [not the raised sections]) to the
highest point on the float.  The float has to be just touching the needle,
not putting pressure on it.

If you grab the workshop manual, there's a (reasonably) good diagram for
measuring float levels.  If you still can't work it out, go download the
workshop manual for the GSX250F (Across), as they're really similar, and
the diagrams are much better.

Hi Malcom,

The idle mixture settings are the four screws on the top of the carbs,
furthest towards the engine.  Stock settings are at 1.5 turns from lightly
seated (in).

To properly tune these, I believe that you'll need an exhaust gas
analyser, though you can tune them by ear/RPM.

You'll be tuning the idle for the smoothest running/highest RPM.  To tune,
turning the screws out makes the mixture richer, in is leaner.  You may
need to turn each one out from stock (making note of how far out you've
turned it) if you've got any inlet/exhaust mods.

What you should do, is make note of where they are now, counting the
number of turns until they're seated.  Set them to the stock position,
then turn each one out (making note of the number of turns) until the revs
peak, then drop off.  Turn the screw back in until the revs peak again.
Re-set the idle after you've done each cylinder.

This may also help you with fault finding:
  http://www.factorypro.com/tech/carbtune,CV,lower_rpm_engines.html

On a side note, do you still have the body of your GS250FW (minus
engine/electrics of course)?  And would you be willing to part with it?


Let us know how you go, and do you have any pictures of your kart?


Cheers,


Carl

Hi Carl

I have not tried any different mixtures. I have the choke connected and when
cold will only start with it and takes a while to get going. Once going and warm
seems to idle fine.

I will check out the float level diagrams and as for the mixture settings, I
don't have a clue so if it comes down to that I'll have to find a good motorbike
mech in melbourne.

Thanks

I'll let you know how I go.

Malcolm

Hi Malcom,

between 5.5k and 7k it's a real dog, only to pick up really nicely.

I wouldn't know about the ignitor, I'd be asking the wrecker about this.

Are you getting good spark?  Have you got the enricher (choke) connected
and working correctly?  Have you adjusted the pilot air jets (mixtures)?

Have you downloaded the workshop manual?

The float levels are measured from the carb-body surface (the majority of
the flat section under the carb-body [not the raised sections]) to the
highest point on the float.  The float has to be just touching the needle,
not putting pressure on it.

If you grab the workshop manual, there's a (reasonably) good diagram for
measuring float levels.  If you still can't work it out, go download the
workshop manual for the GSX250F (Across), as they're really similar, and
the diagrams are much better.

Carl

Hi Malcom,

I'm having a similar problem with mine (though I haven't got the time to
work it out - I think it's fuel related) - mine will rev past 6k, though
between 5.5k and 7k it's a real dog, only to pick up really nicely.

I wouldn't know about the ignitor, I'd be asking the wrecker about this.

Are you getting good spark?  Have you got the enricher (choke) connected
and working correctly?  Have you adjusted the pilot air jets (mixtures)?

Have you downloaded the workshop manual?

The float levels are measured from the carb-body surface (the majority of
the flat section under the carb-body [not the raised sections]) to the
highest point on the float.  The float has to be just touching the needle,
not putting pressure on it.

If you grab the workshop manual, there's a (reasonably) good diagram for
measuring float levels.  If you still can't work it out, go download the
workshop manual for the GSX250F (Across), as they're really similar, and
the diagrams are much better.

I am still have ing trouble starting. and when running very slow to
rev up to a maximum of about 6000RPM.

I have noticed that the igniter the wreakers gave me is from a GSX
750. Could this be a issue?

I checked the timing last night it is fine.

I tried to check the float levels and I am unsure to where I am to
measure from.

If anyone can help me out it would be fantastic.

Malcolm

Wow thanks very much. I will get into it tonight.

There should be two openings into the venturi on the tops of the carbs,
they will have vertical mounting points for tubes.  These tubes are used
for the vacuum operated petcock (which you won't be using on a go-kart).
With these un-obstructed, you'll have running problems, as it will be
sucking in fresh air directly into cylinder 2 and 3.

Try blocking these up, or just connecting them together with a hose or
something, this may fix your problem.

The two that run out of the in-sides of the carbs are just breathers, i'd
prop these up in a spot that's higher than the carbs.

Are you running with the standard exhaust?  If you're running a free
flowing exhaust then you'll either need to change needle possitions and
pilot air screws, or re-jet to get the correct mixture.  I have a feeling
that you'll need to do this anyway, because you're not running an airbox
(which is asking for trouble!).

Backfire out the carbs is (as i've read) usually caused by running lean.

I'd suggest doing a plug-chop (cutting the motor while under load,
coasting to a stop with clutch in) after initially cleaning the plugs and
reading the plugs to get a better feel or what the engine's doing.

Float levels are checked with the float bowl off, you measure off the carb
body to the highest point on the float, with the float just resting on the
(sprung) needle.  From memory it should be 20.5mm +- 1mm, and they should
both be set to the same level).


Cheers,


Carl

Hi Malcom,

There should be two openings into the venturi on the tops of the carbs,
they will have vertical mounting points for tubes.  These tubes are used
for the vacuum operated petcock (which you won't be using on a go-kart).
With these un-obstructed, you'll have running problems, as it will be
sucking in fresh air directly into cylinder 2 and 3.

After a long time I have now fixed my wiring got a new CDI, got
spark, put new head and base gasket onto my GS250FWD with a lot help
from you guys. Thank you

Now I have reached the part where I want the thing to run. I have it
in a go kart. Spark is strong. Exhaust is complete but no air box.

It will only start and run on full choke. it takes ages to accelerate
and will only get to a max rev of aprox 5000 RPM it is a rough and
after it has been running I feel the exhausts and it is hot in
cylinder 1 and only warm in the others. It seams to run very rich and
whilst trying to start can backfire out the carbies.

I have the Carbie set up as:
There are four hoses on the carbies 1 is fuel inlet. and other 2 are
return that I have running to the ground (nothing comes out) and the
other I don't know I have tried it un-blocked and blocked.

Another question is how do you check the float levels. I am used to a
window and level mark.

If anyone can help It will be much appreciated.

Thanks

Malcolm

Well, I'm being lazy and using my partner's yahoo account (but the
email will reach me). Just to let affionados know first that my 1987
GF250 is up for sale - due to my deciding to splurge on an SV650S!

$1700 (slightly negotiable to a good home). Located in Northern NSW.
68000kms on the clock and still running strong (Mr. Suzuki knows his
engineering!). Some pics of the bike as featured on this site can be
found at: http://au.geocities.com/jimr_52/SuzukiGF250data.htm
If you're into collecting, it's original except for the tasty (but
non-Suzuki) paintwork. Frame is showing the rust-stain breakthrough
on
the paintwork that's so common with bikes of this era, and our house
moggy put some minor nicks in the seat surface.
Excellent condition for this model. Gearsack rack will be thrown in
(if you want to spoil the appearance and do some practical touring)

Rego XIK27 (expires end of this month but will easily renew)

Better be quick tho' as I'm putting it on the open market in a couple
of days
Regards
Jim Richardson : jimr@...

Hi Graham, thanks for the info I really appreciate it!! and I'll check over all
the things you've mentioned

From personal experience I would make the following observations

Check for carb flooding, this could be due to
1.                   Corroded needles and or jets.
2.                   The float level may have changed due the bowl
sitting empty and drying out.


Other possible carb problems could be

1.       Water in fuel system
2.       Blocked idle jets (sediment settlement or just blocked)
3.       Blocked fuel lines (fuel cock?)


Drain the fuel and put in a fresh batch, in NZ after three months the
fuel is useless due to the additives and blends breaking down.

Confirm that you have a good spark, if not identify the source of the
weak spark

Subject: [suzuki250fours] Problems with starting

Hi, am having a bit of a problem. Because my bike (GS250FW) had been
sitting for around 4-5 months I decided to get it serviced. The
serviceing has now been done, new plugs, leads, oil, battery, etc but
can't get her to fire. There is no problem with the bike turning over it
just won't start, and I've also tried jump starting in second and third
gear but to no avail. Please if someone out there could give me any tips
on this I would greatly appreciate it.

Thanks for your time.

Anthony
