Alright my kid has proved me wrong. He's been telling me his nearly new yz85 wont shift into 4th. Im like it will shift just go whaaa whaa whaa whaa... and hit the jump. Well he's jumping out of of his seat trying to shift, just a little guy so im thinking it's his boots, right. Until the other day we're doing holeshots and again he's complaining it wont shift into 4th. So dad says watch ill show you and i come back and admjt, ya it doesnt go into 4th under load. So what am i looking at hear, any easy advice.
