Anyone know if any other models shared the same "rear combination lamp" (tail light assembly) as the 1973 TS250? (P/N 35710-30691)

The assembly is discontinued from Suzuki (surprise) but I'm hoping to come across a used one on eBay. So far my TS250 searches have come up dry. I'm guessing the same assembly was used on some other models, but I don't know which.

Thanks for your continued help!

Chris According to my Application Program the 73 is the Only One. I'll try to dig a Little Deeper Tonight.

I have a set of clean std bore 72' jugs, std heads and a set of shaved heads. Plan on putting them on my 76' gt500 while having my original Cyl. bored. im hoping I wont need to change the carb tuning. Yes, as you already know Im a rank newbie.

Will shaved heads be okay to try? .50 i have read that they are okay to run but thought Ild ask? Dofin

[Admin]

I think you'll need to adjust your carb jetting to 72 specs.

Yeap you may have to Go up a size on the Main from the Stock 72 Size and Run 93 Octane.Is that .5mm? Thats not too bad.I think 1.5mm is the Limit on Stock heads.

Thanks good to have a heads up. Dofin

Well worst case has happend. the smooth pistions have smooth rings and they are narrower than the original grooved rings which means the smooth rings are to thin to work in the original pistons with grooves.

When I ordered Std. rings from Suzuki I got rings for smooth pistons but I need ones for the Std grooved pistons. Soooo, guess I will have to find a set of std grooved rings.

That's interesting. My 76 GT500 has smooth pistons and rings, which is normal from all I have gathered. The grooved pistons are the early ones. I don't think yours are original, or perhaps your engine isn't a 76 model. Maybe a serial number check is in order.

Hi all, long time lurker and enjoy all of the various topics and discussions on the board.

I want to begin restoring my 1974 T500 that is in good condition but needing some elbow grease to clean up.

My questions are:

I have discolorations on the battery side exhaust pipe from acid spill I think. Any way to remove that or ir rechroming an option? I'm in the Boston area for suggestions on rechromers.


The frame behind that exhaustpipe has become corroded a little from the battery acid. Any suggestions on how clean up and repaint without taking the bike totally apart?

I want to take the cases off to inspect. Do I need new gaskets when putting back together? If I do where can I purchase them. Also, any recommendations on replacing all of my case screws with stainless steel allen head bolt kits I've seen advertised on ebay.

Thanks in advance for any suggestions. Thanks Jay

Yes, the infamous acid stains. Mine has them too. You can do a surprising amount of improvement with metal polish. If they're really bad, buffing with 800 grit emery cloth with get a lot of it, BUT you will take the chrome off (that's why the stain goes away) leaving only the nickel. It'll shine up pretty well, but won't look quite right and will tarnish more often.

If you can get to the rusty spots with a wire brush, knock the loose stuff off, then use a rust-killer/primer on the area. Check your local auto shop for that. There are several brands; I've used Mar-Hyde One-step a lot. After the rust is sealed, paint it.

Gaskets are available from https://www.partsnmore.com/. If you open the engine, it's always best to replace the gaskets.

Welcome aboard,

Hey Jay Welcome to the Board.
On the Pipes Well to completely get rid of the Stain you'll have to go with a Total Rechrome.Most Chrome Shops won't touch Pipes Because of Contamination to their Setup.You can Probably Polish the Spots up with a good Metal Polish to blend it back in.Since the Top layer of Chrome is Gone your stuck with the Underlying layer of Nickel which will Tarnish.You may be able to patch the Spots up with a Chrome kit from Caswell Plating that you plug in and Wipe the Solution onto the Surface with a Wand.

On the Frame I would Just my Opinion If you don't want to completly Disassemble the Bike I would sand the area Down and Buy some POR15 and Brush it on until you decide to completely tear it down.

If you take the Cases off the Only Gasket you will need is the Cltch Cover Gasket on the Right Side.Yumay Also want to take the Front Sprocket off and Take that Plate off and see if the Oring underneath is OK.Just about all of the Motors that I've ran Across has had sludge Buildup from it Leaking and Fling off from the Chain.You'll probably have to use a Impact Wrench to take the 4 screws out though.

Stainless Case Screws are great but you have to install them with Antiseize because of the Reaction with the Aluminum.Other than that They look Good and you don't have to worry about Stripping the Heads out like with the Original Phillips heads.I have had Several motors that I've had to drill the Heads of the Screws Completlely off then pull the Case and Extract them with Vice grips.Actually the Original Scrws should be installed with Antiseize becauseof the Rust.

I checked the engine serial number and it matches what should be the change over to the GT500 in 76'. (frame 91969 and engine t500-91543). Looks like it should be the original engine.

I seriously doubt that the pistons were changed by a previous owner because there was SO much carbon build up and the rings/pistons where in awful shape.
I dont know when the grooved style piston was discontinued but I sure have them in my bike. Thats not a real problem for now because I am having the cylinders board and oversized pistons install. This will more than likely be one of those things we will never find out. Sort of like the exhaust that are on this thing..

I would also like to use an older set of cyl. with standard bore but the pistons I have for them are old grooved unfortunately I dont have old style rings, I have new style rings I cant use.

anyone want to trade standard gooved rings for a sets of smooth rings?

[Admin]

well, the list on my site is from factory listing supplied by Suzuki Australia...the Swedish list is decidely odd. Wayne, is the frame number on your 74 on the original papers? It is not unusual to swap a frame sometimes if damaged....

If not it just shows that the numbers vary in different markets.
I am surprised no-one has found a US importers listing yet.

For '72 the colors were "Pure White" #064, "Candy Verdoro Green" #263, and the other choice was "Pearl Orange" #264.

Are you guys planning to paint the parts yourselves? I got a quote for the two tanks and side cover for $750. I know a man's got to make a living, but that's how much I paid for the whole bike!

The other choice is to paint the '72 myself with rattle cans, but I'm concerned the paint gets damaged by gasoline. Is this true? Can you clear coat with lacquer or something?

Thanks,
Tom

i would never pay that much for that little unless I was going to show a perfect period reproduction, and even then, the work would have to be flawless.

But thats just me. - For that price I would buy a compressor and gun and learn to shoot.
I agree with Gordon. - You need to ping OGRI to this thread.
