I pulled the rear wheel for a new tire and I also put on new front and rear sprocket. I'm have a fitting issue getting the wheel back on. I put the flanged spacer on the left side. I get the caliper to fit in the swingarm slot, and when I lift the wheel to align the axle holes, the right spacer butts against the caliper at the axle hole. What did I do wrong? Do I need to spread the swingarms? Embarrassed to have such a lame problem, but I know the answer is in this forum.
