Title: GS550 Special - Project Stray Dog - Finished.
Post by: Mad Ratter on Jul 22, 2012, 22:31:10
So, here goes. Down here in Middle Earth (New Zealand) there is not the choice that some of you guys get, being a population of only 4 million. So I was looking for an XS650 to start with, but prices were getting silly, even for dog rough ones and not a lot of choice, so a quick look on Craigslist found a beaut in NH that I could get a friend to ship for me, but it would take weeks, possibly months to get here. I couldn't wait, I needed a project now!, so a look on our very own NZ Trademe site found this sad looking GS550, a deal was struck over the phone (as it was a 5 hour drive away) and went and picked it up, then realising I had paid probably twice as much as what it was worth, ho hum, nevermind.

The plan was to get it going, tidy it up a bit and make it look nice, hack all the junk off it, new seat, paint etc etc, you know how it goes, right? Set my budget, off I went. Well, next day it was pretty much dismantled, I could feel the budget slipping from my grasp already. Then I thought, oh what the hell, just do what you want to it and don't get the calculator out to see what I have wasted, sorry, spent on it. So now the gloves are off, no more Mr Nice Guy, etc, its gonna be what its gonna be and now the project is on!

Here she is as bought, a 1978 GS550 B or C not quite sure.

The tear down starts
(https://lh4.googleusercontent.com/-A7c8OYoB88o/UAyWmA-XRSI/AAAAAAAAARQ/0CM2DP24VzI/s720/IMG_3275.jpg)

Hacked of the rear rails, added a loop, that I had to make it two pieces, (long story) kicked the loop up a bit, cut off the lower frame brackets either side.

Aluminium seat base, stripped paint off tank, full of filler, so the raw steel look is out the window!

GSX-R1100 rear sets, modified. mounted off the one of the original footpeg mounts and the other off the swingarm pivots, perfect fit and position for riding.
(https://lh5.googleusercontent.com/-JEomwPl04Sg/UAyXIEeQc8I/AAAAAAAAAcY/1ztIFDFdd-Q/s720/IMG_3399.jpg)

I dislike the GS cast wheels, so the earlier spoke version was found, again, dog rough but will be powdered black rims and hubs with new shiney spokes :)
Engine being rebuilts, well top end anyway, pistons, rings, pins, clips, valves seals, gaskets etc etc. Ashley from Boulevard Suzuki has been a great help with the parts and shipping as the price here in NZ is horrendous!

Carbs rebuilt with kits from Jerry Cycles. Forks lowered internally by 50mm (2")
So here she is as of this weekend, seat ready for covering, frame 99% done, engine awaiting valve grind, been soda blasted and ready for paint. This stray dog is definately budget blown!

My GS550 project (http://www.dotheton.com/forum/index.php?topic=35598.msg384962#msg384962)

Sure, what I did was drill the rearset plate 14mm (I think) to take the swingarm pivot and the retaining nut sits nicely in the counterbore. The other mount was where I had ground off the original gear linkage flush, then drilled and tapped M8, was a little tricky to get it square-ish. If you see what I mean. You'll need to space it a couple of mm too after its drilled so it sits flat.

Have decided to go with more modern front brakes, SV650 calipers, have made up the mounting plates, made one from thin ally plate then machined the real ones from thicker plate milled down, still need a bit modification, but nearly there.
(https://lh4.googleusercontent.com/-J9jdOmWhU_Y/UAzApC9nf5I/AAAAAAAAAik/uzR1u1WUSvk/s720/IMG_3555.JPG)

Here's the real plates, with slight mods needed.
(https://lh6.googleusercontent.com/-pW2ypf_JayM/UAyiRIzZGoI/AAAAAAAAAgk/D3oprTjiRNc/s512/IMG_3545.JPG)
Here is the seat, cut from high density foam, sanded smooth with an old grinding wheel on the angle grinder, then with thin foam stretched and glued over, gonna laminate 2 pieces of 4 or 5mm ply so that I can copy the kick in the tail, then get it covered.

Today I ordered an engine bolt kit and a Dyna S Ignition from Z1 Enterprises, on that note, does anyone know if I can use this with the standard coils, or do I need "special" ones?

Wow, you guys are eager!!

Ok, its been a long time since I last posted, been real busy, honest!

Its been a bit of an evolving project, I didn't really have a plan that was set in stone as to what look I wanted, I just knew it had to be simple, uncluttered and sleek. I got the engine painted black, I did toy with the idea of the barrels being silver and possibly the rocker cover, but in the end, it all went black, as did pretty much everything apart ftom the tank.
The various parts were powdercoated, including the wheels which were originally chrome, and added some nice new spokes, laced and trued them up (first time for me, that was a challenge!) Here's a few pics of all this.

The wheels before powdercoating and rebuilding

Its close to finished, a few things to do, have put chain and sprockets on now, just a few adjustments with carbs, some small part painting, and a different seat as the one I have didn't turn out as I wanted it, looks amazing but not the style I want, I am going for a quilted look and a higher side seam. This one would suit a Brat bike.
Here are a few photos of Stray Dog #1 next project is an XV920! :) Thank for your interest and welcome all and any comments, critics etc :)

Shame about the reflection in the tank, ha ha! I have included a coiple of HDR shots too, will post the fianl pics as soon as I am happy that she is finished :) Oh, and I may change the headlight as I think a larger one would bring it all more in proportion.

Any suggestions.

You may have to buy separate rims and lace them to suitable hubs, GS750 perhaps? I say separate hubs as the standard GS spoke wheels would, I imagine be too narrow for the look of a GSX1100.

Thats too bad, I was lucky as a guy locally had a job lot of them and bought 2 sets for NZ$50!! but yes some people do ask silly prices for these items. I guess making the bracket would be easy enough for most but the skill comes with the linkages etc.
Hope you manage to locate a suitable set for a reasonable price.  :)

Hi, thanks for the compliment. The wheels are from the very first model from 1977, the only year they were available but I think the GT550 etc shares the same rims. The rear brake is now drum as you can see, as the '77 model was not disc, the front is from my original (1978) model which had cast wheels, I just bolted the discs onto the '77 hubs after machining the hole patterns, as standard has solid discs. Its equipped with calipers and master cyl from a Suzuki SV650, but had to make adaptor plates to fit the original forks, they work great too!

Good luck with your build.
P.S. My Danish is worse! ;)

Awesome looking bike man! I just picked up a 1975 cb550 completely stock.  I was thinking of doing a similar build to my bike as you did. I have no experience with bikes at all as this is my first bike, so I was wondering if I would be way over my head taking it all apart and putting it back together with just a repaire booklet? I do wanna clean everything up, theres a bit of rust on frame and so on, so I guess sand blasting would be my best option? Also, what did you do with your battery to get the hollow look under the seat?
Title: Re: GS550 Special - Project Stray Dog - Finished.
Post by: biggiesmalls on Mar 30, 2013, 21:51:11
Looks great man. Wish I had time/cashflow/knowhow/etc. to do the same ground up stuff for my GS450.
Title: Re: GS550 Special - Project Stray Dog - Finished.
Post by: Mad Ratter on Mar 31, 2013, 03:49:23
Antwan, this was my first build, sheer bloody-mindedness, determination, coupled with a plan and plenty of patience! Oh and depending on how ambitious you want to be, be prepared to pour a significant amount of cash into it too.
A repair booklet? is that an owners manual? Get a proper manual either Haynes or a Clymer, its invaluable!!!

Im no mechanic but do have a little experience and did train as a mechanical engineer, so some of the fabrication was ok for me.

You could clean the frame up without blasting, but its the easiest option I think, then its ready for paint or powdercoat. But dont paint it before you are completely happy with the the look and function as you don't wanna go hacking with new paint on it. Dry build it first.

I decided to go with kickstart only as its a four cyl and easy to kick. That was so I can junk the starter motor etc and just use a small battery, which is hidden under the seat pan. its only about 2" thick, but its a crap scooter battery and not really up to the job, so I am and recommend getting a decent Lithium Ion one like an "Anti-Gravity", not cheap, but like I said it can become expensive depending on what you want out of it.
Mine was kind of an evolving project that sounding like you, I just wanted to clean it up and simplify it, but I fell deep into the rabbit hole :)
Be prepared! and get that manual!
Good luck.

My next project(s) is a simultaneous build of an XV920 and an XS650, I could be in over my head  ;D

Great bike and build... well done....
Working on my own 78 gs550 and love the bars and bar clamp u used. What bars did u use pro taper? What bend are they?
Also I like the look of the single gauge where did you source that from.
Over all a stellar job on the whole project.

Post by: Mad Ratter on May 12, 2013, 06:21:49
The bars in the pic you refer to are wide low MX bars, no brand, just bought off the NZ auction site Trade Me. I have Renthal Ultra Low road bars now, the gauge was from Mikes XS. same ratio as Yamaha's, perfect! all led too, works real well.

The GS 550 is a very nice choice for a bratstyle bike! And you did an excellent job, very nice build and quality work! Incredible that this is your first build.

I am also working on a GS 550 and I am not sure about the size of the rear tire yet. What did you choose? I can see it's a BS Batlax but in which size? 110? 120? 130? Any ideas what is the maximum size without touching the chain?  ;D

I went with the original size, 120/80-18 BT45, I did think about a larger one, but wanted it to handle and steer correctly, I think if you want to go bigger you should lace a wider rim, maybe a 4" for a 130+ otherwise it could be sluggish to turn and the tyre profile would be compromised trying to squeeze too large a tyre on the skinny rim. It does look a little skinny on the back and next time I would go for a wider rim, but not sure of the clearance, tho I think you may only be able to clear a 130.
Good luck with your build and post some pics of your progress!

Thanks Mad! Very helpful advice.

I think I will give it a try and go for a 130 on a 4" rim on the rear hoping clearance is fine. And for sure I will keep you posted on my progress. Like you I will open a new post when my project gets started. I have almost collected all the parts and inspiration I need for it.

I recently got a GS550 (2 in fact) and one did come with a 130 rear tire, so it can be made slightly bigger if you want. Appears to be on the same original rims too

Awesome work by the way!

Hi there, like this bike, nice work! I'm finishing my ''77 gs550. Little problem in the carburator/jet adjustment...
Really would like to know what you are running as pilot and main jet, hope you can help! :)

Wil post a pic if possible.

That looks a real nice build, high quality!!!
It looks like you have, pardon me for saying it, cheap Emgo type filters, not used them before but many have not had a great deal of success with them, best to get the real K&N's then you know its good!!! Get RC-0884, its a kit that includes 2x K&N part # 0880 and 2x RC-2620 so the outer ones are shorter and don't hit the frame.
I have a supertrapp muffler on mine, so all in all my settings will probably be different.

But I have 107.5 main jet, standard pilot jet, needle centre position, pilot air screw out 1 turn, pilot fuel screw in 1 turn for factory setting. Works great and runs sweet. Good luck and get those K&N's :)

Thanks for your help. I will check soon what I have in there now, I thought 110.

And yes those cheap air filters are a waste of money! The outer ones are k&n, and slightly shorter but I like the look of the filters on your bike more.

I'm also looking for a set of calipers from a SV650 ... I think a great improvement from the oem ones.

I'll keep you updated when it's running.

Let me know if you go with the SV calipers and I can give you dimensions etc for the caliper mount plate,

Made a deal for a set of calipers :)
Woul´d be really great if you can help me with the dimensions!

Do you perhaps have a drawing or...?

I also bought bigger main jets (110), i will try them asap.

Here is a drawing of the caliper plate, the curve goes against the caliper and I think the spacers were made from ally and were 24mm thick by 24mm Dia. Picture too of the machined parts. Good luck, let me know how you get on.

Just read on Bike EXIF that you lowered the front fork by 50mm. Now I am curious how you did that. So far I couldn't find any fork lowering kits for the GS550. Do you have any tips or instructions for this upgrading?

As far as I know there are no lowering kits, but its dead easy, remove the damper rod and put a spacer behind the damper spring of whatever length you want to lower it by. I just used some old handlebar tube which was a perfect fit (7/8") and machined the ends square. You will have to remove the same amount from your spring ( I did it from the short rebound spring) unless you want serious preload!  :o which with the GS, you will have to cut it (use a grinder cut-off wheel), you could try say 10mm at a time until you reach the tension you want, but you will have a hard job getting the fork nut back on, a friends help is always welcome.
To show you what I mean, here is a vid I found of Ryca doing just this (but on a different bike, principal is nearly the same), but seems they didn't cut the springs as I guess the LS650 is a soft as the proverbial!

Hi there.
I've been struggling to find a set of those stubby K&N filters for my 1980 GS 550 with the Mikuni carbs. I think they have a 52mm OD. I don't suppose you know the K&N part number for those?! I've had to settle for foam Pipercross filters for now!

Measure the OD with a vernier, then look on the K&N website, but be careful as the ones listed for my model DO NOT FIT properly and the ouside ones hit the frame, 52mm sounds mighty big, but then mine are completely different carbs, not sure that pods work well on those CV carbs either. I had to dig around the forums to eventually find the correct set. The GS Resources forum is good too as they are pretty much GS only.

Outstanding bike Mad Ratter! So good in fact I just picked up a gs550 as my first project bike (currently stripped and in several boxes) and if I can get it looking half as good as yours I will be extremely happy!

Just a couple of questions, did you powder coat the forks or are the bits just painted? Also I plan to upgrade the ignition as well, did you use the original coils in the end or did they have to be upgraded?

My next step to see what the condition the tank is in as I plan to go the bare metal route (still need to work out how to best finish that without rust appearing).

Hi, its a nice build. Inspiration to my own GS500 project, which is on a low budget.
But what I dont really understand is the lowering on the forks, or is mine so different in steering geometry?
Mine overstear a lot, lowering front shouldnt improve that, or do I miss something?

I know this is a old thread but worth a try .Did those calipers improve the breaks .was it worth doing ??
