NOTE This installation requires re-jetting of the carburetors. This is an involved procedure that we recommend be performed by a qualified service technician. If you choose to attempt this procedure yourself, refer to the carburetor removal, disassembly, reassembly, and installation procedures outlined in your V-Star service manual. PROCEDURE STEP 1 Remove the driver and passenger seats from the bike. Remove the negative battery cable from the battery and tuck it out of the way to reduce the possibility of sparks. STEP 2 Remove the two, rear tank mounting bolts. Remove the plastic tank mounting snap stud. (Push in on the center of it to release). Slide the tank back to expose the top of the engine. Make sure the tank is secured so it does not fall! You may remove the tank completely if so desired. STEP 3 Remove the stock air cleaner cover, element, and backing plate. The top and rear mounts are secured with screws, the front mount “snaps” into a grommet. STEP 4 See PIC. 1 and PIC.2. Remove the grommet from the bracket. STEP 5 Placing your long handled Phillips screwdriver as shown in PIC.3, loosen the clamp on the air duct and remove the duct. Remove the clamp from the duct and set it aside, as it will be reused. Now is a good time to proceed with re-jetting of the carburetors. Consult your factory service manual for this procedure. We have supplied jets to cover most common applications.
