Welcome to my man cave

Man cave
A proud owner of a new Man Cave

Welcome to my blog where I describe my journey in Suzuki GT restauration.

Hopefully at help for myself an others with the same interest. Scroll down for for new posts.

The main idea with this blog is to use it as a reference guide for Suzuki GT 750A  and GT 380J model.

Donā€™t hesitate to give me feedback and guidance if you see me doing it wrong.

Latest update: Got the resin yesterday and did a test print.

Was very pleased and easy to fit the part. A bit stiffer compare to the “real” rubber, but still flexible. Get much softer at temperature. Let it rest in hot water for some minutes before mounting.

3D printed light knob

After a long time of nothing, here is a new post on my blog.

The image above is from my CAD model done in Fusion 360. I used the lightswitch knob from my GT750 as a template. Started by drawing a sketch around the knob, took a photo of it and imported into Fusion 360. Compleated the CAD model in Fusion360 and made the printer file.
The knop was printed on a Prusa Mini printer in PETG filament.

Here is the result, mounted back on my GT750. Not a perfect finish and I tried to polish the surface a bit. Not easy to do, because the heat from the pad can easily melt the part, as it did on the top. On the other hand, if you ruin the prat, just press reprint button and make another try šŸ™‚

This was only a sample to test the technology. The knob will be needed for my GT380 and I will also make a new print using a resin printer, able to print in a better resolution and a smoother finish. The new printer is on it’s way from China and will hopfully arrive at the end of February.

Please feel free to download the light knob if you want to make you own print.

Anti-surge jets

I bought a new carburetor kit last summer and mounted it for a couple of weeks ago. Interesting to compare with the old one I had. The first test run was promising. After a longer ride I got more and more annoyed about the surging at low rpm. Pretty sure it’s more surging compare to the old one. The fuel consumption is better and the color on the spark plugs looks also better while using this kit. If I can get rid of the surging I will keep them on the bike.
The new carb kit has no anti-surge jets mounted. The previous owner said they are all tapped and ready to be fitted with jets.
I don’t have a new jet-kit, but I have a lathe and milling machine. Let’s make a set of three 0,8mm jets.

Bulletins no 36 explain how it’s mounted :

Jet fitted:

Please read the application note no 36 and follow the procedure how use the 4mm tap.

Test ride:

Very pleased with the test run. The annoying surging issue was gone. šŸ™‚

GT750 startup 2020

As usual, instant start on the GT. First ride this season. The spring has been horrible cold so far. Was snowing for a couple of days ago. Will enjoy the short MC season on the GT750 this year and hopefully the GT380 will be on the road the next year.


My GT750 A tank is back from repair and has got a new paint. My nephew Thomas has once again done a fabulous work on this. I’m so pleased with his work.

On my ride to the classic Suzuki rally in Denmark last summer i had an accident and got an annoying dent in the tank. Now it’s all gone šŸ™‚
