My brother has a kdx 220 and he broke the Exhaust valve advance lever on his bike. i know it is broken because i found it in the bottom of the motor when i replaced the clutch. This lever is the piece that is attached to the bottom of the KIPS shaft with two screws. It is located in the right engine case. My question is....can the bike be riden like this....it does not seem to affect the power that much and it is ridable. i will replace it as soon as i can but in the meantime he wants to ride it. What do you say?
