Okay, so I have an 85 it 200, bike has been maintained well. But about 2 months ago I was riding on a hot day, made sure there was oil and such in it and mixed the gas 50-1. Usual things. After I got done riding, I turned the bike off and the engine seized. So on and so forth, took the top end off, got to the crank, unseized the bearings and put it all back together with a new piston. Now when I start the bike, there is a rather consistent ticking about every 1-3 seconds. Anyone have any idea?
