I appreciate the comments. I do not recall a ball on the end of the pushrod so I will start there since I have to replace the kicker shaft assm. We'll drop the cable in a pan of oil later today.
We plan on passing the YZ on in the next 6-12 months. My boy takes after mommy thank the lord. He's barely 105# and 5' tall and turns 14 next week. I figure he will gain another 2-4" and 50# by summer. I am hoping to find a decent older dual sport which can transition to a license like a KE100, dr125se, NX125 or similar. I've got a line on a 2000 KE100 for $500 and hope to see it today or tomorrow.
