Piston Ring Squaring Tool

thingiverse

I'm working on a Simple Piston Ring Squaring Tool that makes the job of squaring rings when setting and checking piston ring gap a whole lot easier. The bore feature can be modified, I've found that using the bore diameter minus 0.5mm works well for me. For my SV650 with +2mm, an 83mm tool fits the bill perfectly. If you're working on an FZ-07 with standard bore, an 80mm tool is what you'll need. This little DIY solution is a cheap but effective way to square rings and make sure your piston ring gap is just right.
