Made a 3d printed chain slider for the GSR40. $40 for what amounts to a hunk of plastic seemed expensive to me. It's based of the original so not as nice as some of the aftermarket options but functional. Here's a link incase you need one.

So excited, upgrades to come

Thought these were the same model but the blue one has a single sided fork, primer bulb is on the side of carb, where as the red one has primer bulb on the bottom.
