Finally I got the resin printer and did a reprint of the light knob. Much better result compare to the first prints I did using an ordinary 3D printer with PETG filament. From the resin printer there is no need for any refubrishing, looks stunning right from the print.
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 🙂
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.
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.
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.
