I have my bike (650R)torn down and have the swingarm completely disassembled. I was talking to a local shop owner and he suggested I silicone all the holes in the swingarm to keep water out. I have also read on here somewhere that some of you guys have drilled and tapped small holes with a bolts in the bottom of the swingarm legs to allow water out if needed. I'm trying to figure out where exactly you drilled the holes. It looks as if the end section where the axle goes through fits in the end caps of the swingarm leg and welded. I would like to drill my holes just in front of the weld, but not sure if that end cap section is a solid block of aluminum. Has anyone done this to their 650R? Please share your experiences and if it has helped.
