Pics please. :D

Landsvw 01-03-2020 08:36 AM

I’ll get a few pictures today. right now it’s spaghetti wiring... first thing tho, I’ll pull off carbs. Inspect and clean. Then, start working on the wiring. Get the thing to crank, with spark. See where I can go from there!

If she runs, I’ll have to add to the fleet and update my signature, ☺️

Every time I run across a good project bike in good shape there's always that "No I don't have the title" statement. :ohno: My first bike I owned was a 6 month old Honda CB200 that the previous owner had completely disassemble the engine because it had a broken selector plate for the shift. He definitely wasn't a mechanic lol The guy told me if I wanted I could have it then handed me a box of engine parts and handed over the title. :D I had that thing put together and running the next day.

Those are sweet old bikes; something about the sound is very appealing.

Landsvw 01-03-2020 01:37 PM

Yes, they are neat old bikes. I guess they caught on and sold like hotcakes back in their time. Suzuki must have gotten it right. I never had a GS but my dad had a GS1000 and rode it from Alaska and back a few times.

Price on this one was also, 0$.

Picture this: slightly modified GS550 Dual Sport. That’s my vision.

Sport Rider 01-03-2020 01:50 PM

do this to it!

That is actually really sweet. I’m 55 tho and married. I can’t see myself zipping around on that. First of all, would need ibuprofen after every ride, and second, the cougars already attack me because of my Boxster... my wife says it’s dangerous leaving me in it in the parking lot... cute car and wife’s cute tiny dog... the upside is, no cougar could fit on the back of that thing. And I could out run them!

dude....I'm 59. pass 4 more ibuprofen please! :p

Sport Rider 01-03-2020 03:53 PM

seriously though...I did see a few nice scrambler examples too!

Landsvw 01-03-2020 03:58 PM

That’s a cougar magnet! Hahaha! Also, yes. TGFMI. Thank God for more ibuprofen.

;)

Yas! We are teenagers in old fart bodies. How did that happen?

Landsvw 01-03-2020 05:12 PM

I played a staff vs 8th grade boys b-ball team game 2 weeks ago. I was good for 5 minutes a quarter. Of course, we won. But I tell yah. Ibuprofen came in handy that day... I still mentally, have the skills but my body was screaming what the heck.

I prefer Teenager in an AARP Body. I also never put any stock in “Act Your Age”.

Last week, it was my SIL and I against the grandkids in two hand touch football. They started out talking trash and the next thing they knew, they were down 36-0. Grandpa can still sprint. And paid for it the next three days.

ok fellers,
you asked for it. here's the carnage so far...

Landsvw 01-04-2020 07:40 PM

3 out of 4 intakes are bad. wiring issues, but i can easily fix that. not much else... carb 1 has a stuck slide and i drained them all and goo came out... so i'll be removing 4 bowls and cleaning 4 carbs. ugh... i will first do electronics tho. get spark and tidy everything up. know anyone who has some intake manifolds, cheap?
;)

Landsvw 01-05-2020 10:34 AM

looks like 4 intakes for 29$ on Ebay. woo hoo!

That sounds cheap enough.

Landsvw 01-06-2020 12:31 AM

update: got the engine to spin. figured out a bit more of the electrics. worked on the front brake, as the caliper was seized but had a good used one. the master cylinder seems to have issues so i'll take that apart another day.

Landsvw 01-08-2020 10:45 PM

A little progress was made tonight. sorted some wiring and ordered an original fuse box with some undamaged wiring for 10$ from Ebay. Should be in next week. Evidently, original owner had tried to rig up aftermarket fuse panel, but, eliminated the pre-fuse (bigger one) and then, when they wired it all up, the ignition wouldn't turn anything off because everything had been run (the hot to the ignition and leading away from it) back to the aftermarket fuse box... was a mess... but, not irreparable. :)

Also found that the CDI ignition, the original one, was bolted to the bottom of the airbox. Someone had cut the wires and then just run it to another one (same kind luckily) and had it dangling in the frame... So, Not sure why they cut the wires and the plug off and then butt-connected it back together. I may fix it right or maybe just wrap the butt-connectors in black tape the way they had it...

I'd actually wager a bet that the original one works, seeing how this wiring is so crazy.

I absolutely love projects like this; when the machine is fundamentally sound but all this little cheap stuff is messed up. It's like a Jenga game with a running motorcycle as first prize at the end. ;)

Weldangrind 01-09-2020 12:13 PM

We all know you're gonna fix the CDI wires properly. :D
I watched a video yesterday where it was mentioned that multi-carb setups need to have the sliders set to the same resting height; I've never heard that before. Most of my experience has been with single carbs, so it never occurred to me that the resting height of the slider was adjustable. Is there a provision for adjustment on your carbs?

franque 01-09-2020 12:45 PM

It's probably just syncing the carburetors. Usually, you're adjusting the openings of the butterfly valve on the throttle so that the engine is pulling the same vacuum through each cylinder. It's easier than it sounds, as long as there aren't any air leaks.

On a non CV carb, I'd imagine it's like adjusting the play in the throttle cables, if it's one cable per carb, or I could potentially see it being like adjusting the idle on a single cylinder piston valve carb, as generally multiple carbs don't have individual idle adjustment.

On my R80RT, you have to balance the carbs, and there's individual idle adjustment for each carb. It's a bit finicky, but not too hard to do if you're patient.

OneLeggedRider 01-09-2020 04:02 PM

Those are CV carbs and easy enough to balance with the proper equipment and a little patience.

Landsvw 01-11-2020 12:30 PM

i ordered partial wiring with 2 fuse boxes from Ebay. should be in Monday. However, I'm mystified because the 'main' fuse, looking at the old one, and at the new ones, doing google research and also looking at the wiring diagram doesn't do anything! I wonder if it's a throwback useless fuse to before they switched to electronic ignition? the older bikes seem to have the same fuse, but not the larger 4 box... it's really weird. anyway, i'll still hook it up like factory, and this should eliminate all the home made wiring. Moving forward!

Landsvw 01-11-2020 07:08 PM

Today I finished the front brakes (disassembled master cylinder). replaced the fluid. took apart speedometer since screws had fallen out of the face and the face turned so I couldn't read the mileage. Has 17,000 on it...

hmm, what else? waiting for electronics parts.

Oh, i took off carb bowls. 1 and 2 nasty. 3 and 4 ok. will do a Redneck rebuild (carb cleaner and put back together) and i think things will work ok.

Landsvw 01-12-2020 09:32 AM

ordered the 4 intake manifolds... :)

here's the schematic for this weird separate fuse that goes nowhere. There is a terminal in the box, but why is this here?

I'm thinking holdover from earlier models with points, but what the heck?

it's actually a separate fuse holder, not a 5 fuse holder like the schematic shows.

the white box is the fuse to nowhere (Like an Alaskan bridge I've heard about).

I've confirmed this with multiple pictures and searches, and mine, which has most of the parts there (but not the 4 fuse box because it's been replaced with an aftermarket which doesn't flow the current correctly).

OK, update. Official Suzuki sites with parts schematics are calling it a 'power source'. So, maybe it was designed for just that. If a person wanted to run extra electrics on their bike, this is the tap for that.

Weldangrind 01-13-2020 12:33 PM

Cool! You could install grip heaters or a USB port for charging your phone.
Love your Neil Peart reference; Canadians are in mourning.

We old rockers love Rush. I saw them 2x. He wasn’t only an amazing musician but also a thoughtful amazing human. So are the other two.

Landsvw 01-13-2020 11:29 PM

I got my little 10$ package of wiring in! installed in easily. too cold to go further today. lets see, other than that, when i can get a few free hours I'm almost ready to crank it to see if it has spark.

also, figured out the fuel issue. the automatic (vacuum activated) tank switch was stuck closed. fixed that (looks brand new too; not a speck of corrosion).

waiting on the intakes! :)

Landsvw 01-18-2020 09:44 PM

reassembled carbs. stuck the new manifolds on. got the thing to putt putt and verify that electronics work, etc. ran for maybe 5-10 seconds without choke or throttle cable hooked on.

but, something choke related is missing... seems to be the cable. Will investigate tomorrow. highly encouraged by what I heard tonight tho.

Landsvw 01-19-2020 08:40 PM

Carbs 1 and 2 are leaking so am working on that. Float needles are not sealing.

cheesy 01-19-2020 08:43 PM

Float needles or cracked float bowl overflow tubes?

Landsvw 01-19-2020 08:50 PM

Well, I’ve got the carbs on the bench. Attaching a fuel source to them makes gas pour out the back of the carb on the right two. I’m predicting float needles are still cruddy.

cheesy 01-19-2020 10:47 PM

I predict you are correct.

Landsvw 01-19-2020 11:42 PM

I’m trying to ‘get away’ with not buying any carb parts... ugh... might not. Figured if it gets running decently, I’ll run some sea foam through it and cross my fingers hehehe.

Weldangrind 01-20-2020 11:50 AM

You might be able to clean the seats with a Q-tip and some carb cleaner.
