Well...... Cleaned carb again used all different types of wire and probed every carb hole I could, made sure everything was spotless. Could eat off it. Motor now won't fire... Hmmmm... Checked spark... Got spark. Checked fuel, got fuel. Airbox fitted, yep. Valves adjusted. No need they are within spec. Finger over spark plug hole, crank motor... Hmmmmmmmm Compression gauge found in my massive mess of a garage. 80psi. Lowest recommended is 113psi. Pulled the head cover off... Which forms part of the camshaft housing, the end section of the cam is badly scored so the head cover was as well. So now I'm at a turning point with this bike. Do I A. Rebuild it. B. Source a gs125 motor from a wreck of a more modern version that bolts in. C. Bin it. D. Find something else. Which knowing me... Will need work. The bike other than the running issue is 99% complete. I Bought this for myself for turning 40, I wanted something to tinker on... I did however almost buy a brand new klr650... Probably should of done that.

So I bought this bike last year as a project for my 40th, it now runs, but I suspect an issue... Is this just me hearing things or do I really hear dry bearings etc? Gs125 YouTube link Gs125 noisy motor YouTube link 2 after oil change and heat cycles. Not part of the plan to pull the whole motor down.

It gets worse. Small chunk of alloy and the whole bottom of the side cover was full of metallic sludge, it moved with the magnet. Alot of heavier pieces too the same texture as sand, it obviously has had some water sitting in it for a while. The thing is the motor does run, but what worries me is how long for... I'll do an oil and filter change in it and wait for the new air filter box to show up and go from there. I'm not rebuilding it. It was meant as a cheap run around bike. Motors for these aren't easy to come by in Australia.

First oil change... I suspect this is a flood bike.

A risk we take when buying a cheap old bike.. will give it afew oil changes and see how it goes.

Hey everyone, I'm looking for an air filter housing for a 1982 Suzuki gs125es. Very hard to find here in Australia.

Finally had some time to rebuild the carb. It runs a slide carb unlike the newer models. I can get it to start and run, has an unreliable idle and after a rev the revs will hang and slowly come down eventually. I can't find any air leaks. With the original carb what settings should I start with for the mixture screw? I can find plenty for the newer carbs but no settings for the slide carb. Also the needle settings, I understand I should be making it richer because of the excess air it's now getting with the pod filter.. Still trying to find an original air box.

Looking for some parts for my 1982 Suzuki gs125. But I need someone willing to send them to Australia. Factory air box with rubber, (now before everyone says these can be found on AliExpress etc, they are a different air box to suit some type of delivery trike. Unless there is a different one I can't find?) Side covers

Here she is in all her 125cc goodness.

I haven't ridden a motorbike for about 8 years and this little nugget came up really cheap about an hr away and I just had to buy it. She needs some love and some parts, no air box so the previous owner put a pod filter on it which the bike hates obviously. I don't feel like re jetting so I'd prefer to find a stock air box. Needs some new side covers as one is missing and the other has cracked. Rear tyre is cracked and doesn't hold air. Rear gear has been worn to sharp points. Seat is stuffed.... ...gee maybe I shouldn't of bought it haha, but I'm a sucker for older bikes. But on a bonus the gauges are very good, the controls as good, has original Suzuki plastic under the key which looks good and when I can get the motor to run it sounds healthy. But it just runs horribly. I had a play with the carb slide today and made it run abit richer which it will run and now rev however the revs hang at 3000rpm until I let the clutch out abit to drop them down. Plans: Big tidy up, new tyres, round front headlight, hate the rectangle one as it's missing the surround anyway. I work one night per week so will update the headlight for the roads I'll be taking of a night. We do get the occasional kangaroo and I'd like to see it before hitting it. Little rack on the back or some low profile panniers, I really just want a comfortable ride to work so I don't need to take my 4x4 everyday. Cheers from Oz, Josh.

Hello, I have been riding on and off for the last 15 years. Sold my last bike afew years ago now and saw this old 1982 Suzuki GS125 come up for sale cheap and I just had to buy it. Parts for these old girls are hard to find in Australia and I have noticed alot more in the UK and Europe etc. She does need some work, runs the factory Mikuni slide carb, missing the factory air box, it's been replaced with a pod filter but the carb hasn't been jetted for it so I need to sort the air box as it runs horribly. Plans are to get it really tidy, add a rack on the back and some low profile panniers and just enjoy it as a commuter bike to work. Cheers Josh from Oz.
