INSTALLATION 1. This lowering method requires replacement of the front spring spacers. This is a simple task, and is completely reversible. First, raise the front tire off of the ground before you begin. Raise the motorcycle so no weight is applied to the front wheel. 2. Cover the gas tank with a thick towel to prevent scratching. Don’t omit this…you’ll be sorry if you do! 3. If the handlebar risers are OEM (stock), loosen the handlebars in their clamps and lift them from the risers, carefully placing them on the gas tank on a thick towel to prevent scratching. This will allow room for the spring spacers to be removed from the front forks. 4. Using a small knife blade, sharp screw driver, etc. in the pinch grove on each side of the triple clamp, gently pry upwards and pop the chromed plastic covers off. These are the covers on the top of the front forks, covering the spring retainers. Below these chrome caps, you’ll find a gold anodized metal plug with a small counter bore in the center. This is the part used to retain the springs within the front fork tubes. Using an extension bar, large Phillips screwdriver, etc., press down a bit in the counter bored area of the plug to take the pressure off of the small internal “C” ring. While this “gold” colored plug is depressed, remove the internal C-ring. The C-ring is made of small diameter wire. Once the C-ring is removed, slowly release the pressure on the plug and it’ll push itself out of the top of the shock. The picture below is of the upper fork leg with the gold retaining plug removed. 5. Stick a finger into the fork tube, and slide the OEM tubular spacer up and out of the fork tube. 6. The picture below illustrates the use of a Scootworks lowering spacer with the fork spring. On the right hand end of the you’ll see a Scootworks lowering spacer. The fork spring stays in the front fork, and you’ll drop in the spacer with the desired amount of lowering. The approximate amount of lowering is marked on each Scootworks spacer. 7. Select the spacers for the desired amount of lowering. The longest spacers supplied are marked as [1] and will lower the front suspension 1″. The spacers of middle length are marked as [2] and will lower the front suspension by 2″. The shortest spacers supplied in the kit are marked as [3] and will lower the front suspension by 3″. Omission of the spacers completely will lower the front suspension by approximately 4″. 8. Install the selected spacers in the fork tubes, on top of the internal fork spring. Place the gold anodized metal plugs on top of the spacers and press them back into the fork tube. Be sure to turn the metal plug so the side with the counter bore is facing outwards. Reinstall the C-rings, and gently lower the front end back to the ground. Make sure the C-rings seat themselves in their respective grooves when the weight of the bike is placed back on the front end. Re-install the chrome caps.

1. Place a blanket folded several times over the fuel tank to prevent any damage during the installation of the risers. Loosen the two 19mm riser mounting nuts located on the bottom side of the upper steering head. Pry out the chrome plugs from the heads of the four handlebar top clamp bolts using a knife blade. Loosen the four handlebar top clamp 6mm socket head screws. 2. It will help having a second person to hold the handlebars while you change the risers. Remove the four screws from the clamps and then the clamps. Pull the handlebars up off the risers, pull them back and rest them on top of the blanket. 3. Remove the nuts from the bottom of the risers and remove the risers. Insert the two supplied spacer tubes into the riser mounting holes on the upper steering head. Using the bolts, lock washers and washers supplied install the new risers making the bolts finger tight only. (Take care not to scratch the top surface of the upper steering head while installing the new risers.) 4. Place the handlebars back up onto the new risers. Reinstall the top clamps using the four socket head screws removed earlier. Set the height of the handlebars to the desired position, tighten the front bolts first and then the rear securely. (15-18 ft. lbs. There should be no gap between the riser and clamp at the front side.) Tighten the two riser mounting bolts securely. (20-25 ft. lbs.) 5. Turn the handlebars all the way to the left and then right checking for any pulling or binding of the wires, hoses or cables. Also check that the throttle returns freely on it’s own

Removal of the Brake-side Bearing Cup The bearing cup (5) is located endwise by a circlip (1), and between the cup and circlip arc an oil-seal retaining washer (4), oil seal (3), and oil-seal cup washer (2) Before these parts can be removed from the hub the bearing cup must be moved inwards for a very short distance (3/16-inch) so that the circlip can be withdrawn. (n) Gently heat the hub shell. (i) Place a soft metal rod (e.g. brass) against the oil-seal cup washer (2) and apply pressure with a hand press or hammer blows. It is only necessary to move the bearing cup (5) inwards about 1/16-inch. (j) Extract the circlip by inserting a narrow pen-knife blade under one end of the circlip; lift it upwards and outwards and prise the clip out of its groove. (k) Remove the oil-seal cup washer (2), oil seal (3) and oil-seal retaining washer (4). They can be hooked out with the shank of a small and narrow screw­ driver, (l) The bearing cup can now be ejected by placing a suitable rod of soft metal (e.g. brass) in the hub tunnel from the right-hand side and pressing it — with a press or hammer blows — against the bearing cup until the cup is forced out of the bearing. This must be done with care so that the cup remains square with the housing. Reassembly To facilitate replacement of the bearing cups gently heat the hub shell. Just too hot to hold is about the right temperature. (a) Place the brake-side bearing cup squarely in the hub shell — the open end faces inwards — and press it into the hub tunnel A short length of brass rod, slightly less than the outside dia­ meter of the cup, should be interposed between the cup and ram of the press, or hammer head. Press the cup in until the outer face is approximately half-an-inch below the mouth of the hub tunnel. This will allow sufficient room to allow [he circlip to be inserted into its groove. (b) Refit in the following order: oil-seal retaining washer (4), oil seal (3), oil-seal cup washer (2). (c) The circlip can now be replaced. In the interest of reliability use a new circlip, for it is possible that the existing circlip was strained when it was re­ moved. (d) Insert into the hub tunnel from the right-hand side a brass rod of suitable length, and press the bearing cup firmly against the circlip. (e) Before inserting the spindle complete with the roller races, pack them with clean and fresh grease of a suitable grade (Mobilgrease No. 4. Castrolease heavy, Energrease C3, Esso Pressure Gun Grease. Shelf Retinax Grease CD or A). (0 Insert the spindle into the hub. (g) Place the right-hand side bearing cup in the hub tunnel; the open end faces inwards, It may be necessary to re-heat the hub to allow the cup to go into position without difficulty. (h) Press the cup into position, but do not force it fully home, leave some end play on the spindle. (i) Refit in the following order: oil-seal retaining washer (6), oil-seal (7) and oil-seal cup washer (8). (j) Screw into the hub the adjusting sleeve (9) until it comes into contact with the bearing cup (5)
