GT185 was very popular in the UK because of our peculiar licensing / learner laws which
restricted novice riders to 250cc machines until they'd passed their riding test. This

choice.<BR><BR>The early one that you have is quite rare

No...the clutches weren't any weaker than normal. One of the main problems with the 550 is
the battery/charging system. EVERYTHING must be in first class shape i.e. fully charged
battery clean electrical connections throughout corect wire sizes etc. You can pull the
starter out and dismantle it to check brushes armature cleanliness etc if you wish and

suspect that regulator has a bad resistor in it allowing too much battery voltage into the
field coil and thus allowing the alternator to produce too much juice. Hard on the
alternator. Hard on the battery both in and out.,H2RICK,

74 GT 550 timing,Thursday 28-Sep-2000 20:52:16,63.52.230.203 writes,Can someone tell me
what the heck's going on? I go to set the timing on my 1974 Suzuki GT 550 exactly like it
tell me to in the Clymer's manual. Using a dial indicator I find TDC and turn the
crankshaft back to lower the piston 0.132 inches. But when I go to adjust that cylinder's
contact it is fully open. Even with the maximum adjustment I could do to the contact I
would be no-where near an area on the cam that would close the
points.<BR><BR>It starts ok I guess. And after warming up for
3 minutes during a 55 degree day it will stay idling. But not that smooth. I tried to
adjust the carbs. Closing the idle jet completely on a carb didn't change the way the bike
was idling all that much. So I decided to start with adjusting the point gap. Then set the
timing. And then come back to the carbs.<BR><BR>When I move
the accelerator more than the smallest amount (1/2 inch) of the total it like bogs down
with hardly any acceleration. And the sound of the bike changes to a more muffled
sound.<BR><BR>Any help would be appreciated on any of these

noting that the T500M appears to have used a different piston from the earlier models. My
factory parts book shows that the same part number is used for the T500R J K and L but a
different part number is used for the M in 1975. If earlier pistons were not used in a
rebuild then it may be that while the bike is registered as a '75 it is actually a late
'74 that was first registered in '75. It would be interesting to know the serial

bike is the same colour as mine but I'll bet it was just pained in the '75 colour scheme.
I have seen another T500 late '74 production bike that was also registered as a '75 and in
the same blue. However a close inspection indicated a T500L. For example the rear pegs

by the local vintage guys (car club and bike club). Weather was beeeyoootiful. About 75-80
degrees in a great park down by the river.<BR>Rode from home in sweats and
jacket cuz it's early fall here in Calgary up at 3500 feet and 50 degrees latitude. By
10:30AM off come the sweats<BR>and on go the shorts and big golfers straw
hat.<BR>Man it got warm. Over 50 bikes showed up with the newest being an 81
GS550 Suzi (a little worn but what the heck). Bikes next to me were an RE5A rotary CB550K3
Honda and a Kawi H2B all in very nice shape. Only 2 Harleys in the bunch and these were
both pre-war (1928 and 1935 if I remember correctly) so they were acceptable. Also on
display was an unrestored 66 Suzi 80 with a high pipe. Pretty decent for a bike that old.
Talked to a lot of guys about bikes cuz the show was well publicized. The crowd numbered
about 800-1000 people so yakked with a lot of "civilians". I'm standing looking
at a really nice early 80's Laverda Executive (reallllly rare) and a guy comes up to me
and says "Are you Rick ?". What could I say...I admitted it. Then he says
"Rick So & So ?". Nope not me but "why do you ask" says I.
"Well" he says "I just bought<BR>a Suzuki GT500. Do you know

late and let the frost go away. Anther beyoootiful Saturday.....WOW.....two in a row. Haul
Indy out of the shed and go rat racing around town looking at bikes at the various shops
and generally yakking with people and end up at the bike wreckers on the south
side<BR>scmoozing with guys trying to fix 25 and 30 year old bikes. In rolls
a T500M with a guy looking for parts. Yackity yack. The yard also has a GT500A for sale
complete and not bad except frame left side cover is missing. The bike runs
great<BR>(some piston noise) and they want about CDN$ 800 for it. If my shed
would hold another bike I think I would have bought the darn thing just to save it from

<BR>new Mustang GT V8 automatic and some kid on a mid 80's Kawi 750 of some
kind. All in all a pretty satisfying Saturday. The Indy just drank gas like
<BR>a mid 70's Caddy and produced thrust like the space shuttle all day.

00:48:43,209.197.132.28 writes,No that resistance measurement is shown in the service
bulletin as just the bare slip rings with no brushes in place. Also as you mentioned in
your original post on this thread that you had 0.1 ohms from the rotor shaft to the
outside of the rotor. This is normal as the outer part of the rotor is pressed onto the
shaft and so there is naturally continuity between them. The clear reddish-purplish
varnish insulation on the magnet wires of the field winding and the light brownish
insulation cloth is what keeps the field windings insulated from the rotor shaft/outer
surface. <BR>Again I believe you have a partial short in the rotor windings
as your 6 ohm reading is about half what it should be. Probably what has happened is that
the wire windings of the field coil have expanded and contracted enough times rubbing
against each other all the while and rubbed that insulating varnish off themselves about
halfway through the total length of wire in the coil. Thus...6 ohms instead of 10-12 ohms.

value.,H2RICK,

Someone wrote to me in response to the question of "why is the 2 brushes connected to

them.<BR><BR>All I can say now is that I should have figured
it out when putting it together. And NEVER TRUST a Clymer's manual again. The picture they
have of the alternator doesn't even show that bolt and washer. Instead it shows the other
bolt and it's typical lock washer assemby. And since it showed the one bolt and how it's
assembled and not the other I figured that it was an identical assembly. Isn't that the

thank everyone who helped me with my problem. I learned a lot. Unfortunately I have a

Re: Re: Hallelujah !!! ,Wednesday 27-Sep-2000 08:51:11,24.64.0.9 writes,A) the dial gauge
method of timing is the most accurate way. However if you look in the manual there is also
the "rough & ready" way of timing with an ohmmeter and the little three
pronged<BR>"propellor" that sits on the end of the crank BEHIND
the points & condensor plate. That little<BR>propellor has timing marks
on it for all 3 cylinders. The manual tells you how to proceed with setting of the timing
UNLESS you have an older manual with which I am not
familiar.<BR><BR>b) What you want is to have a maximum of
approx<BR>14.5 volts being put into the battery at idle/low engine speeds
and heavy electrical loads (headlight on high beam turn signal on etc). Whichever
regulator will give that value is acceptable. Don't forget there are 2 other modes of
regulator operation that must work also. We'll call the max charge mode Mode 1. The medium
charge is Mode 2 and (I don't have the book in front of me) I believe the regulator is
supposed to put out about 11 or 12 volts at this point. Mode 3 is the "no
charging" mode. This mode only happens under high RPM/low electrical load conditions.
The battery is fully charged at this point and has sufficient current to power the system
without needing charging. The current normally going to the field coil in Modes 1 & 2
is shunted to ground by the regulator in Mode 3. Without any current to the field coil the
alternator cannot produce a charge. I believe the Clymer gives you the various voltages
into the battery at various engine speeds. If not post back and I will see if I can dig up
the info for you.<BR>This is all very easy to see on your
voltmeter<BR>as you rev the engine and apply different electrical loads in
the 3 modes mentioned above.,H2RICK,

GT380 porting for power,Wednesday 20-Sep-2000 13:47:27,216.111.5.126 writes,Craig and
H2Rick were talking about GT380 power and how the engine was so conservative well I had 5
of these beasts and thought the same! The 380 has true pure Schnuerle porting with no
auxillaries or boosters and the ports are quite small in height and width. I got a great
idea from examining my GT250 which basically had the same porting but with one major
difference: the exhaust port had 2 small ports on either side near the top to effectively
widen it without the risk or loosing ring support. I know how to take a hint and drilled
two 1/4 inch holes on either side of the 380's exhaust port the tops of the holes being
equall with the top of the exhaust port. Next I used my Dremel and a carbide bit to drop
the bottom of the new holes 3/4 of the way down towards the bottom of the exhaust port and
slightly ovaled out the tops of the holes. Next I drilled 2 3/8" holes in the piston
skirt on the intake side just on either side of the intake port but so as not to fall in
the ring gap areas. Then using the Dremel I cut two troughs or grooves if you will in the
cylinder walls that were even with the tops of the tranfers and the bottom of the grooves
were even with the holes in the skirt at BDC. Basically I added 2 booster ports angled
right at the plug and widened the exhaust with webbed holes to support the ring. Next I
had the head milled to set the squish at .040" and went up 2 jet sizes on the mains
used Uni-Filter foam on the stock filter cages and re-packed the silencers. Talk about a
difference.....It would do roll on wheelies in first just snap the throttle open and enjoy
the view of the sky! The 380 would crap out at about 7K but this one would pull hard all
the way to redline and you didn't need to take it that far to get all the thrills you
wanted. I got the booster idea and drilling the holes in the skirt from Aerimacchis and
RDs that I had seen back then. I never told anyone until now as it was my big speed
secret........and later I forgot about it altogether. Now that I don't have the bike I
might as well tell everyone what I did. ,jmendoza,jmendoza@datum.com

> Does the fuse still blow with the regulator in circuit and the field windings and

both the rectifier and field windings with no fuse blowing. But what surprised me was
being able to have everything connected (including the regulator and rectifier) with just
the male connector for the alternator disconnected from one of the main 3 connectors by
the regulator and rectifier area. And no fuse blew.<BR><BR>Add
the above data with the fact that if I remove the regulator with everything else connected
it doesn't blow a fuse. I'm just too confused to figure what to test
next.<BR><BR>Thanks for the help Peter. Any other suggestions
(no matter how far fetched) please send them my way.<BR>,Gregp,

writes,Addendum:<BR><BR>The latest news is that I'm able to
connect everything where it's supposed to be without blowining a 10 amp fuse. Except the
green connection on the brushes assembly. When I connect that up the fuse blows. Does that
mean I need to get a new alternator? Thanks. BTW the 3 amp fuse blew right away so I
jumped to the next biggest fuse I had.<BR>,Gregp,

writes,Greg:<BR><BR>I'm back and your description on this
thread means that your field windings in your rotor are shorted as mentioned previously.
That's what the green wire to the regulator is...the filed wire. With the key on and
engine not running OR running at idle the battery current flows to regulator and then to
the field coil in the rotor THROUGH the brushes via the green wire. Deep six the rotor and
get a new one or good used one with 10-12 ohms across the slip rings. You might be able to
get the local motor rewinder to rewind your existing rotor for you but that usually costs
more than a wrecker would charge for a used one. End of story.,H2RICK,
Compare GT 550 & 750 front fork internals,Thursday 14-Sep-2000 17:22:13,12.76.122.83
writes,I have a 74 GT 550. That makes it a K model right? I bought a GT 750 front end
because of the dual disks. I don't know what year it is. The outer (lower) tubes are the
same size and look the same internally. The 750 forks had the rubber boots on them instead
of dust seals. The 550 dampening rods are solid rods with shorter springs and a spacer
about 5" long at the top of the fork. The 750 forks have hollow dampening rods with
holes drilled down one side and longer beefier springs and no spacers. The inner tubes
look the same on both sets but the pistons are shaped differently. What would be the best
combination of these fork sets? I am trying to build a vintage roadracer. My Clymer manual
just says that the forks are "generally similar for all models". Have the 550
forks already been modified with the shorter springs and spacers? I know what the safe
thing to do would be but does anyone know what would give me the best front end? I already
have tapered roller bearings new wheel bearing and an aluminum front rim. Please help.

Front Fork Problem,Wednesday 13-Sep-2000 17:57:29,199.247.128.35 writes,I am restoring a
'75 GT750 during the strip down of the front forks the Socket screw on the left fork will
not release. It seems to just spin is there a possibility that the Damper Rod is spinning
free within the tube. If so are there any tricks to releasing the socket screw before I
consider drilling the head off the screw?,Michael Hanson,

Re: Front Fork Problem,Thursday 14-Sep-2000 11:16:45,209.37.128.111 writes,I've had the
same problem numerous times with various forks. What I found best is to break the allen
bolt loose before removing the spring. Also as much as I hated to part with the $$ I
finally broke down and bought an electric impact wrench from Sears. It turned out be money
WELL spent. It makes these type jobs ALOT easier.,Alt,rgwanab@usa.net
Engine wanted.,Tuesday 12-Sep-2000 23:21:34,64.193.239.137 writes,Looking for an engine
for a '68 T500. After trying every possible chemical
I could think of (and letting it soak for a month) and every possible method I could think
of to remove a corroded barrel I resorted to my BFH and after 75 whacks (using the hammer
as as baseball bat) I was able to get the barrel off of the case. Needless to say the
barrel was destroyed. The upper case is cracked around the drive gear (not by my doing).
So I am in the market for a trashed engine that I can salvage the upper case and the
barrel(s). The oil capacity modification had been done to my engine so all trans parts
look fine. I would like to retain the bottom case as I am restoring the bike and would
like the numbers to match if possible. If anyone could tell me either what year engines I
should consider or any leads on an engine that would suit my needs I would be eternally
grateful.<BR>Best regards.<BR>Greg

question were the 380s. US and UK markets got the 371cc version (54 x 54mm) and some
markets eg. Italy got a 384 cc model (55mm bore 54 stroke).<BR>This came to
light because importing bikes from Italy is quite popular in the UK and a Classic Bike
reader wrote in with his findings. He foud out because the R/H barrel had 384cc cast onto
it rather than the usual 371cc. <BR>According to the owner's manual for that
bike Suzi claimed 41bhp @ 7500rpm which I think is a bit optimistic. I've no idea what if
any other modifications were made by the factory: I guess they had the same head porting
cases but you never know with Japanese mfctrs ...<BR>They may have made the
550s in different capacities too but I've no evidence for this.,Craig,
