CAUTION When delivered the front fork legs have no springs installed. Provided are two different spring pairs, rate 4.1 and 4.5 N/mm. If a rate of 4.3 N/mm is desired a combination is made by using a 4.1 N/ mm spring in one fork leg and a 4.5 N/mm spring in the other fork leg. When the springs are mounted make sure that the spring support is fitted too. See Mounting Instructions for set-up data.

WARNING! 1. Installing a front fork, that is not approved by the vehicle manufacturer, may affect the stability of your vehicle. hlins Racing AB cannot be held responsible for any personal injury or damage whatsoever that may occur after fitting the front fork. Contact an hlins dealer or other qualified person for advice. 2. Please study and make certain that you fully understand all the mounting instructions and the owners manuals before handling this front fork kit. If you have any questions regarding proper installation procedures, contact an hlins dealer or other qualified person. 3. The vehicle service manual must be referred to when installing the hlins front fork.

Tuning the suspension

Motorcycle road holding qualities All motorcycles are designed with a suspension geometry that includes height and fork angle. The changing of components can affect this and it is therefore essential that both the rear and the front ends match each other.

Changing to hlins suspension gives optimum performance only when both the front fork and the rear suspension interact properly. It is of the greatest importance that the front and rear loaded heights are within the specified values. In the Mounting Instructions, see section: Setting the spring pre-load.

trapped above the oil) that work together with the real spring. You adjust the air-spring by raising or lowering the oil level in the legs. By using different combinations of springs and

air-springs you can alter the characteristic of the fork. For example, a soft spring in combination with a small air-spring (high oil level) makes the fork progressive; see Fine-tuning the bike.

Marking All hlins front forks are marked. You will find the part number on the inside of the fork bottom.

Recommended settings The front fork in your kit is adjusted to the hlins recommended setting for your bike. We advise you to use this as your start setting.

Design hlins new upside-down (USD) front fork is designed to combine the advantages of com- fortable, safe conventional forks and rigid, light USD forks. The result is a unique combination of being rigid, precise in corners and during hard braking yet comfortable, forgiving during over- landing and in big bumps. Your new hlins USD front fork has aluminium

outer legs and 48 mm steel inner legs, with a polished surface for lowest possible friction. The new USD fork features the hlins cartridge

damping system. The fork is fully adjustable with external adjuster

for compression and rebound damping. The compression adjuster is located at the

bottom of the fork leg (Fig.1), the rebound adjuster at the top (Fig.2). Spring pre-load is adjusted with spring supports

of different heights (Fig.3), and optional springs are available to suit different tracks and riders. In the legs there are also air-springs (the air

Settings

Basic settings Always ensure that the basic setting made by hlins is correct. It is adapted to the make and model (in its original state) and for a rider of average weight.

WARNING Incorrect spring action can produce a fork angle that is too steep or too flat.This in turn will give a tendency for oversteering or understeering, which could seriously affect the handling characteristics of the motorcycle.

The original setting of the front fork, when delivered from hlins, should always be a base when the settings are changed by use of the adjustment devices.

Recommendations Follow the recommendations given in the Setup data of the Mounting Instructions. If none are specified there, use the below recommendations.

Free sag: (R1-R2), (F1-F2) Rear: 305 mm Front: 305 mm

Ride height: (R1-R3), (F1-F3) Rear: 30% of the total stroke Front: 805 mm

Setting the spring pre-load

Measuring Pre-load on the spring/springs is very important, because it affects the height of the motorcycle and the fork angle. Consequently, handling characteristics can be changed, even negatively. Proceed as follows (it will be much easier if done by two persons):

Place the motorcycle on a stand, so the front fork and the rear end are in fully extended position.

Measure the distance, eg. from the lower edge of the rear mudguard or from a point marked by a piece of tape, immediately above the rear wheel axle, to the wheel axle (R1).

Make a similar measurement on the front axle, e.g. from the bottom of the upper fork crown to the front wheel axle (F1).

Allow the motorcycle (without rider) to apply load on the springs and repeat the measuring procedure (R2, F2).

Then take the same measurements with the rider and equipment on the motorcycle (R3, F3). It is important that the rider has a correct riding posture, so that the weight is balanced on the front and rear wheel in the same way as when riding.

Fine-tuning the bike Learning how to use the adjusters will take time but you quickly appreciate them once you know the tricks. Even the specialists sometimes need a specialist! With the adjusters you optimize the suspension

for your riding style and the track you are com- peting on. The same basic guidelines go for both the front

fork and the rear shock absorber. Too much compression damping will give you a

harsh ride as your bike jumps along the track. With too much rebound damping your bike will

have difficulties with several bumps in a row. The suspension will not extend fast enough between bumps, your bike will ride lower and lower and eventually the suspension will bottom!

External adjusters On the hlins front fork the adjusters are bleed valves, completely separated from each other. The compression bleed valve controls the flow

in the cartridge tube during the compression stroke, the rebound bleed valve controls the flow during the rebound stroke.

CAUTION! Using too much force when closing the adjust- ers will destroy important sealing surfaces.

Make sure that you have the correct springs and the correct spring pre-load before making any adjustments. And always start with the hlins recommended settings.

Compression stroke Rebound stroke

Flow in compression valve Flow in rebound valve Flow in compression valve Flow in rebound valve

NOTE! Higher click numbers give less damping force.

When making adjustments, keep notes, make adjustments one at a timeand in small steps. The adjusters should normally not be adjusted

in steps of more than 2 clicks at a time and not outside the usable click range. When you think you have made an improvement,

go back to what you started with and double check to be sure. Pay attention to changes in conditions like tires, temperatures etc.

NOTE! See Mounting Instructions for recommended settings.

Both the adjusters have a normal right-hand thread. Click position zero (0) is when the adjusters are turned clockwise to fully closed. The adjustment range, from fully closed until maximum open valve (anticlockwise), is 20 clicks. In order not to click in the wrong direction; always first close the adjuster, then dial-in the new setting.

Making adjustments To make improvements using the adjusters, it is important to understand the function of the front fork and the shock absorber and through testing learn how they effect the handling of your bike.

In general, compression damping changes should be used to influence the bikes stability and re- sponse, while rebound damping changes should be used to influence comfort and traction. When you need more damping force, you should

mainly try to increase compression damping and use as little rebound damping as possible. This usually means that you gain comfort and

performance in handling.

Oil level adjustment As the air trapped between the oil and the top nut acts as an air-spring, a change in oil level will effect the damping forces. Not in the early stage of fork travel, but a great deal in the later stage. A general description of how the oil level/air-

spring effects the damping forces are shown in Fig.4. The air-spring gives the hlins USD fork a

progressive spring rate, preventing it from bottoming out hard.

By using different combinations of springs and oil levels/air-springs you can alter the characteristic of the fork and tailor it to suit different tracks and conditions.

CAUTION! The oil level must be the same in both front fork legs. Riding a bike with different oil levels will cause instability.

When the oil level is raised The air-spring in the later half of travel is strong, and thus the front fork hard.

When the oil level is lowered The air-spring in the later half of travel is soft, and thus the front fork soft.

CAUTION! Adjust the oil level with the fork leg fully com- pressed and no pre-load washer or spring installed.

NOTE! See Mounting Instructions for recommended oil level.

The oil level is measured from the top of the outer leg, with the top nut off (Fig. 5). Changes in oil level should be made in small

steps. We recommend a change of 5 mm at a time and not outside the range of 80-130 mm.

CAUTION! The fork legs have two fixed bushings and one sliding bushing. Be very careful when disassem- bling the fork legs.

Fasten the fork leg horizontally in a vice with soft jaws. Use a hot air gun to warm up the outer leg where the bushings are located, at the bottom end of the outer leg. A sleeve is mounted above the bushings to maintain the correct position.

11 Use the special tool 1702-04 to remove the bush- ings. Install the tool in the top of the inner steel leg. Screw the top cap onto the tool and install the

cap in the outer leg. Rotate the tool to press out the bushings. If tool 1702-04 is not avaliable, push the inner

steel leg to the bottom and then pull it back quickly, so that the fork is topping out hard. Repeat this procedure until the seal and the

bushings can be pulled out from the outer leg.

CAUTION! This must be carried out with great care to avoid damages on surface and bushings.

Maintenance Telescopic front forks depend on a smooth, friction free action. Make sure your forks are regularly serviced. Do not use strong solvents, such as brake

cleaner, to clean the front forks. This will dry out the seals and the steel tubes and cause friction or leakage.

After every race Clean externally and spray with an all-purpose oil after washing with detergent. Check externally for damage. Put a little hlins red grease (146-01) on the steel

tubes and work it in by pushing the fork up and down.

Every 20 hours Dismantle the fork and check all parts for wear and damage, replace if necessary.

NOTE! Discarded hlins products should be handled over to an authorized work shop or distributor for proper disposal.
