Info

ATTENTION! This indication alerts you to the fact that ignoring the contents described herein may negatively affect product performance and functionality. DISCLAIMER – PLEASE READ BEFORE PROCEEDING: Any modifications to a motorcycle’s exhaust or intake tract require carburetor re-jetting to achieve maximum performance and maintain drivability. If you are uncomfortable with the process of tuning your carburetor, we recommend that you bring your motorcycle to a qualified motorcycle mechanic to have this kit installed. The jets included in this kit were selected based on test results with various combinations of components that we felt would represent the majority of the customers purchasing this kit (see Addendum I). However, no two motorcycles are exactly alike. Depending on the individual case, additional jets may need to be purchased from an outside source. Kuryakyn warrants the parts included in this kit to be free of defects in materials and workmanship, but makes no claim whatsoever in regard to costs associated with installation or tuning. strIctly Observe the fOllOwIng guIdelInes In Order tO use the PrOduct PrOPerly and avOId POtentIally dangerOus accIdents. PrOcedure steP 1 Remove the driver and passenger seats from the bike. Remove the negative battery cable from the battery. steP 2 Remove the two rear tank mounting bolts. Remove the plastic tank mounting snap stud. (Push in on its center to release). Slide the tank back to expose the top of the engine. Make sure the tank is solidly in place so it does not fall! You may remove the tank completely from the bike if you’re not certain the tank will stay in place while you are performing this installation. 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 With a long shaft Phillips screwdriver as shown in PIC.3, loosen the clamp on the air duct and remove the duct. Remove and set aside the clamp from the duct, it will be reused. steP 6 Re-jet carburetor. Refer to factory service manual for disassembly procedure and to Addendum I for baseline jetting recommendations. steP 7 Install a Line Fitting Plug into the threaded hole in the Skull Air Cleaner back plate labeled as “A” in PIC.4 and tighten snugly. steP 8 Install a 90 Degree Elbow into the threaded hole on the Skull Air Cleaner back plate labeled as “B” in PIC.4. Tighten snugly. steP 9 Insert both flanges of the rubber air duct through the opening in the mounting bracket. See PIC.5. PIc.5 steP 10 Wet the radius portion of the intake duct with soapy water solution and slide the Skull Air Cleaner back plate into place on the intake assembly. See PIC.6. When positioned correctly, the Skull Air Cleaner back plate should be between the two rubber flanges on the intake duct and the 90 Degree Elbow and Line Fitting Plug will be below the rubber intake duct. -cont.- Page 2 s k u l l a I r c l e a n e r PIc.1 PIc.3 PIc.4 PIc.2 A B InstallatIOn ®
steP 11 Line up the three holes in the back plate and the three holes in the flange of the rubber intake duct with the three holes in the support bracket. Insert the three supplied 1/4”-20 x 5/8” socket head cap screws through the face of the Skull Air Cleaner back plate and secure on the back side of the main support bracket with the 1/4”-20 thin Nylock nuts. You will need to pull back the inner flange of the rubber intake duct to access the holes. Hold the Nylock nuts with a 1/2” wrench as you tighten the socket head cap screws with a 3/16” hex key. See PIC.6. steP 12 Place the galvanized clamp hook on the duct clamp as shown in PIC.6A. You will need to flatten this hook on the clamp. Place the Stock duct clamp on the new intake duct. The clamp screw should face forward. See PIC.6B. steP 13 See PIC.7. Loosely install the mounting bracket and duct using the included M6 x 1.25 x 15mm socket heads and tapered socket head bolt caps, the front location will also require the step (reducer) washer and the M6 flanged nut. Slide the intake duct onto the air box but do not tighten the clamp at this time. Loosen the clamps securing the stock rubber elbows to the carburetors and air box. Gently wiggle the air box to ensure that the rubber intake duct is fully seated on the air box inlet (removing the air box lid makes it much easier to see if it is on completely). Once everything is situated and comfortably in place, tighten the clamp on the rubber intake duct first and then tighten the clamps on the stock rubber elbows. Replace the air box lid. Tighten the mounting bracket fasteners completely at this time. (PIC.7 shows the assembly thus far with out the back plate installed). steP 14 Set the air filters into position on the back plate. Place the filter cage over the filter and secure be threading in and tightening the three 1⁄4”-20 x 1” BSCS fasteners from the back side of the back plate into the filter cage. steP 15 Set the Skull Cover in place, lining up the 3 mounting holes. Insert and tighten the three 1⁄4”-20 x 3⁄4” SHCS fasteners and clear nylon washers through the skull cover securing it to the air cleaner assembly. It would be a good idea to use blue lock tight (not supplied) on these 3 fasteners. Do not over tighten. steP 16 See PIC.8.This is the float bowl vent hose. Connect this hose to the 90 Degree fitting on the back plate. steP 17 Replace the fuel tank and re-connect the negative battery cable, re-install seats. steP 18 Recheck to make sure all fasteners are secure, no hoses are kinked, and throttle operates freely. ATTENTION! It is the installers’ responsibility to make sure all fasteners (including pre-assembled) are tightened before operation of motorcycle. Küryakyn will not warranty components that are lost due to improper installation. Periodic maintenance may be required. addendum I. The following recommendations are to be used as a starting point only, but should work well in the majority of cases. Individual bikes may need additional tuning to achieve maximum performance. These baselines were established at 700 feet above sea level. -cont.- PIc.8 s k u l l a I r c l e a n e r PIc.6 PIc.6a PIc.6b PIc.7 Page 3 InstallatIOn ®
