    New GS250T Owner --- Restoration Build

    Hey everyone!

    I finally was able to pick up an old motorcycle last week that I can work on restoring to pass time on the weekends. I did pay about retail (according to KBB) but the body and paint were worth it to me.
    I now own a 1980 Suzuki GS250T. The owner listed it on CL and stated an oil leak on the left side (said it was the side cover), needed a new battery, probably clean the carbs and that's it. Well there was allot more than that! It was sitting in a shed for years. The owner said he stopped riding because of the oil leak and he had another bike and never got to it.

    Day 1:
    Got to work on it this past weekend and fixed / discovered allot! I removed the battery which was bone dry and filled it with distilled water then threw it on the charger. While that was charging I used a jumper to try and get the bike to turn over so I could at least hear if there was motor knock. Hooked up the jumper to the terminals and low and behold... nothing. Not even a click. Did some research and testing and I narrowed it down to a bad starter relay. What I did instead was disconnect the black (starter) wire from the relay and touch it off on the red lead on the relay (from the battery). The starter turned over and that's when I heard the joyful sound of a happy motor with good compression.

    At this point I was too excited and couldn't wait on the battery so I grabbed some starter fluid and ran the starter while I sprayed fluid into the air box. Nothing. Gave it full throttle and the starter and it coughed to life and eventually
    came to an idle on it's own. She lives

    Took her outside and started her again, she starts right up, barely any choke needed. Full tank of premium fuel and sea foam and I'm thinking I can avoid taking apart the carbs. When the battery finished charging I put it on and it worked, so that's 100 bucks back into my pocket

    The front brakes were locked up so I did have to remove the caliper to move it around. At this point I got to work on the caliper. I grabbed some lithium spray and Shot allot in between the boot and the cylinder and used a large C-clamp to open it and then the brake handle to close it. I eventually got it working again and put it back on.

    First Test drive:
    I drove around the parking lot to see how she runs (1st and 2nd gear). Everything was going smoothly until the chain fell off. I put it back on and got to adjusting the chain tension. Now there is a nice kink in the chain (might have been there before but I just noticed it.....) this chain was LOOSE!!!!!

    So I drove it home very carefully and decided it was time to trace down the oil leak (it was pretty bad like the owner said it was). I first pop off the sprocket cover and that's when I immediately see something that made me cuss out the seller... a bent clutch push rod. I had never heard of this problem until I just discovered it and when I asked the guy if the chain fell off with him, he said no..... Yah right. So now I was looking at major work and even worse, that part is no longer available. This is when I went inside for the night to do research before going to bed.

    Day 2:
    Through my research I discovered the clutch push rod is no longer available and the only options where to have a machine shop fabricate a custom one, or purchase a newer two-piece unit for a 550 and still have to fabricate it to fit. I decided to go ahead and take the rod out before I place any orders and spent the next 4-5 hours taking all but one clutch cover bolt out (and stripping one) and driving all over the place to find cap head screws that will fit. I ended up using a impact screwdriver to get that frozen /stripped bolt out. Was so bad I skewed the Philips head bit (but then again it was CHINA). I ended up needing M6 x 1.00 x mm head cap screws. Quantity: 1x20mm?, 4x45mm, and 8x35mm. Unfortunately I could not find any 35mm so I

      Initial Maintenance

      Welcome fellow "T" owner.

      You've discovered and temporarily resolved some issues. That battery issue is concerning...what was your power source?

      Next, I would suggest a caliper rebuild as soon as possible. Take a look at the brake line for brittle rubber. I'd suggest a braided line and a master cylinder rebuild as well.

      Your chain falling off sounds like more than a loose link. What's the inside of the front sprocket area look like?

      Take some pics of the areas you are working and start threads in respective areas.

      Sounds like a nice little bike. I started on a 750 so I can't imagine what a 250 feels like.

      EDIT: I had to get a pic of said bike:

        Mine was a very nimble little bike and a lot of fun. Sadly, it met its' end when an idiot ran a stop sign .

          I'm sorry I didn't know this wasn't the respective thread location? I didn't see anything about builds unless I read over it.

          TRT at least your fine, you can always replace a bike.

          GSXR The sprockets look fine, the chain was just super loose and I forgot and took it for a spin in the parking lot because I couldn't wait. It was a little bumpy so That's probably why. Backed out the rear wheel and havent had another issue but I do need to replace the chain soon because of it.

          Also, I am a seasoned rider and just wanted something to keep me busy and I always wanted a classic bike so I got the 250.

          Continuing:
          I ended up buying some 40mm bolts and cutting them down to size. To resolve the clutch rod issue I removed the bend rod and took it into work to measure it with calipers. I read 0.236 inches (manual calipers), then comparing to a sizing chart I concluded that it must be a 6mm rod (0.2362") so I went to McMastercarr and ordered 2 ft of 6mm stainless steel rod and it was at my dorrstep before I got home from work (great service!). My other reasoning s that Suzuki would have to design by a standardof parts availiable, in this case a shaft seal with a inside diameter of 6mm.

          To custom fabricate my own push rod I ended up cutting the old one at the point where the steel and brass met. Then I cut a 6mm rod to the length of what I cut off and filleted the edges. To get it to work from there I simply put everything back together on the clutch side (installed the brass end of the old rod) and then slid my 6mm rod in from the other end. Adjusted the clutch under the black cap to where the sprocket cover would just sit flat while not pushing on the rod. I must say... the clutch works PERFECT. Smooth as butter and the best part is if it happens again all I have to do is take the sprocket cover off, slide out the bent piece and slide a new one in. I have enough steel for about 6 pieces! I'm now just waiting on a new seal so I don't leak oil everywhere.

          I drove it about 45 miles yesterday and a couple things came to my attention.
          1) I'm definately rebuilding the brake caliper, master cylinder, and getting a steel braided line.
          2) It seams to be low on power (no power past 5k rpm).

          So last night and part of today I removed the carbs (very nice carbs btw) and got to cleaning them only to find out they were clean as a whistle (I guess seafoam did it's job). I then put everything back together and started it up (now it's only running off that battery, it does loose charge but still carries it for a few days (a new one will come eventually). After I got it all together I started it up and it still felt low on power. While it was in neutral I revved it up to 9k rpm and that's when I knoticed the problem. It seems to "die out" at 4,700 rpm and then pick up again (but without the same pull). It just feels like it's being starved or somthing. Also, I changed the sparkplugs today. The ones in the bike were old NGK D8EA. I replaced them with that. Is that even the right plugs?

          Currently trying to figure out that issue. Will post that on the correct thread location though (after a few searches of course)

            Oh and GSXR I rode / raced Sport bikes so this thing is a scooter for me lol. Last bike was a tracked out GSXR 600. I would fly by the 750s and 1ks in the twisties but the stacks would close in on the straights and I would just hang with 750s. Miss that bike. Rode it all over GA, AL, TN, NC. Fun times.
