Fitting Instructions:

• Slide the rubber boot down and disassemble the throttle housing, remove the old throttle tube taking care not to damage the throttle cables.
• Carefully remove grip from the old throttle tube if required.
• Inspect the cables and housing for excess damage or wear, clean and lube them or replace if required.
• Clean the handlebar and inspect for damage where the old throttle tube has been spinning on the bar if a ridge is present replace the handlebars.
• Slide the new throttle tube on the handlebar and lube using a penetrating lubricant preferably Maxima MPPL (do not use grease as this attracts dirt and makes the throttle stick after a short period of time).
• Re-assemble the throttle cables and housing again using some penetrating lubricant.
• Tighten the throttle housing in the correct position on the handlebars.
• Adjust the cable to the required (free play amount) of your liking.
• Rotate the handlebars to their maximum position to check proper operation of the throttle and correct cable routing, some re-adjustment of the cable may be required.
• Slide the rubber boot back over the housing.
• Cover the hole in the end of the grip with some electrical tape (To stop glue entering the throttle barrel) and apply a small amount of RFX grip glue to the outer end of the throttle tube on the outside diameter.
• Apply a small amount of RFX grip glue to the inside of the new grip and slide onto the tube.
• Twist the grip to the correct position and leave to dry.
• Apply RFX safety grip wire if needed.
• After the glue has dried again check proper operation of the throttle.
