So I'm pretty sure I have a slight knock or piston slap in my Blaster. My wife's runs much smoother than mine. The tick sounds like it's coming from the top end. Based on what I have learned from reading here I should invest in a leak down tester, and a compression tester. I should probably pull the head and check for slop/play in the piston as well. I am assuming the cylinder needs to be bored to a new piston. Both Blasters are 100% stock, no work except regular maintenance. My wifes Blaster wasn't ridden as hard as mine I'm thinking. Hers does need new front wheel bearingsb, but that looks to be an easy task.
So have I done my homework? Is there something I may have missed?
