Chain slack is 15.X/16in, which is 24mm.
22-25mm is spec. Looks like I'm fine, except need to oil the chain, and maybe clean if anyone has any recommendations. My plan is just simple green and a toothbrush.
..is this pure coolant? what does percentage of water matter? pretty sure it's supposed to be 50% but dunno why. also dunno why coolant needs to be changed every couple years. I've got like 8 gallons of coolant so if I need to replace it or add deionized/distilled water that's NBD.
