Throttle Shaft Viton U-Cup Seal

$ 10.50

Replacing these seals is not a simple job. We recommend that home mechanics seek out a technician who has experience disassembling throttle bodies and installing these seals. Our service department can help you! Need Qty 4.

To replace them, you need to remove the two screws on the throttle plate, which may require grinding since the screws are peened over. Then remove the bell crank from one end of the shaft as well as the spring. Pull the shaft out of the throttle body to access where the seals go. Take pictures and notes, as it is difficult to reinstall those springs correctly. These seals are the same in all models, as well as most throttle bodies and carbs in Japanese bikes.
