Barkbuster Fitting Instructions
- With a sharp knife cut a hole in the end of the left and right grips, retaining the outside lip.
- Loosen the throttle assembly to move it outward about 20mm. Roll back the end of the grip and use a hacksaw to carefully cut off the endcap of the plastic throttle tube. Do not remove more than 3mm from the end. This is performed easiest with the throttle tube still on the handlebar; be careful not to cut the underlying handlebar.
- Choose the correct size expander insert(2) for your particular handlebar. Note: Tapered Mounting Kits are supplied with only the 14mm size expander insert. Insert the 8mm outer handlebar mount bolt(1) through the handguard(4), expander insert(2) and 8mm cone nut(3). Only thread the bolt partially at this time. (See Diagram 1)
- Fit the handguard with expander hardware installed into the end of the handlebar until fully engaged. With a 5mm allen key, tighten the bolt only enough to hold the handguard in position.
- Loosen your clutch perch, throttle assembly and front brake assembly if not already and any other necessary parts to position and align the handguard in position.
- Loosely assemble the clamp(5) to the handlebar and the handguard(4). (See Diagram 2) Note: For tapered clamps 01, 02 & 03 there are rings machined into the inside of the clamp surface to assist you with a correct fit. The rings on both halves of the clamp should line up with each other and be positioned towards the centre of the bike on both the left and right side.
- Position the handguard and controls until you are comfortable with the fit. Do not allow any part of the handguard to interfere with the controls. Make sure the throttle tube and grip does not rub on the expander or handguard. It is important to set a 3mm working clearance between the throttle grip end and the handguard to ensure a free closing throttle. Tighten your controls to OEM specifications. Note: You may need to bring your controls inward to give proper clearance between handguards and the levers as well as the throttle end.
- Important Clamp Fitting Procedure. The clamp bolts must be tightened in the following order. (See diagram 3). Tighten bolt(6) through the handguard(4) to the swivel section of the clamp assembly(5). Tighten bolt(7) to solidly lock the swivel section into the clamp assembly(5). Tighten bolt(8) to secure the clamp assembly (5) firmly to the handlebar. Note: The clamp is designed to allow the nut on bolt(7) to pull into the recessed hole. This eliminates the need for a wrench after the bolt starts to tighten.
- Finally tighten all handguard and control bolts securely. Important: Check operation of all handlebar mounted controls specifically the throttle, front brake, kill switch and clutch to ensure they are operating correctly and are in accordance with the OEM specifications. Do not operate the motorcycle if the throttle is sticking, not self closing or if any of the controls are not operating correctly. (Check periodically that all bolts are tight).
