I am rebuilding a YZ450F and everything is OK, but a transmission.
it felt perfect on 1, 2nd gears, but slight hesitation on 3rd and worst on 4th gear.
It feels like clutch keeps ON & OFF as frequency.
It accelerates and but still hesitating.
I tried to remove TPS, and gonna lower clutch disk numbers (I put as many as it can take).
I checked condition of transmission gears when it engine was open. But everything and every gears' condition was mint.
What would be the cause???
What should I do?
WHat should I check next?
