FLOW ADJUSTER KIT 'FA-48' 2017-2020 

Our successful 'FA48' Flow adjuster kit has been revamped, tuned and further dialed in over the last 2 years resulting in further gains and upgrades available for your WP Xplor fork. All updates available and will work with the 2020 models right back to the first year Xplor in 2017! 

Fits all WP Xplor Forks 

After a lot of feedback from our test crew, riders and customers we have worked out more options with this kit offering higher performance, even more adjust-ability and most importantly greater value.  

Our ‘Flow adjuster kit’ comes with a Mid-speed piston and new post assembly matched with a tune able shim stack to suit the Xplor48 fork.  This completely swaps in as a replacement for the very weak OEM Wp comp adjuster on the compression side cartridge rod. The Krooztune ‘FA’ fork cap is tuneable in fine increments allowing for a true 20+ clicks of workable and huge noticeable adjustment!

The latest addition of a 'Base adjuster'  we find a working range of around 16 clicks. This achieves a much more plush feel over the rocks and logs with huge gains in plushness without making the fork overall too soft or a mushy feeling.  

The powerful 'FA' adjuster can be set from a super firm setting (1 click out from full in) all the way through to a plush setting at around 18-20 clicks out.  Winding or clicking this Adjuster on the FA fork cap actually changes the comp shim float in the mid speed piston allows super powerful adjustment. Almost like a soft MX like setup to super plush setting in clicks.

Full Kit Includes:

• FA Adjuster cap
• Base compression adjuster
• 2 x base compression pistons ( fitted to both sides )
• Base compression shims / settings
• New refined Mid valve assembly/adjuster complete with shims ready to go
• 3 optional base shim settings - Soft/Medium/Firm
• Full fitting instruction manual 
• 12mm Clamp kit to install midvalve assembly

Setting

Our kit comes with 3 shim/setting options. We install Medium on all our kits unless advised otherwise, we can arrange to already pre set your option. Please leave in comment box at check out.  Setting sheet supplied

Setting:

1. Soft - Suits plush setting absorbs all intial hits with ease. We have great results with this with our Vet / Older guys that dont want to get beat up all day on long rides
2. Medium - Average fitness, Average speed great all round setting . A balance between soft and firm. Bump absorption with great hold up.
3. Firm - Ex Mx racer or fit / fast/ tall guy riding on the trails at pace?  This setting works well for guys that like a firmer mx style feeling.  Rip hard fast Trail's ease.  Still not too firm but enough to charge hard, setting developed with our in house Vet mx racer after loving testing on the KTM EXC range.  

See table below for our experience found in tuning our kit once installed, highlighting the main issues we found on our testing program.  We would adjust in these increments until great rider feeling is achieved.

**Clicks firmer 'in' clockwise direction / softer is 'out' anticlockwise** All Setting adjusted from the supplied 'Base Clicker' Setting

Test riders found a comfortable window fairly quickly that suited their ability and terrain in a matter of minutes.  After dialing in your FA adjuster for great hold up on downhills and landings, the fine tuning for tree roots, rocks and logs can be fine tuned with our base compression adjuster giving you the plushness and softer feel in your hands when riding the trails or racetrack.

The Setting is simply not 'stuck' on the Suspension tuners setting/valving specification.  Once installed you have the ability to virtually 'revalve' on the fly!

 Key Updates for all kits developed for 2020 

• 4 Port compression pistons for finer tuning ability and less ‘blow out’ on big hits. We can achieve firmer compression setting whilst retaining a plush feel changing to this design. Fitted to both fork legs with shim stacks supplied for easy install.
• Fine tunable Compression Base adjuster. This replaces the stock non adjustable unit,  fitted to the bottom of the rebound fork only. This adjuster fitted to the rebound leg only will offer greater noticeable changes in compression setup. First off it runs a bleed from the system straight away making this plusher in hand. With a working range of around 4-20 clicks it allows for fine tuning of the compression on tree roots, rocks and small logs.  Take the sharp hits out while not adjusting the powerful flow adjuster. Ultimate Settings can be achieved by balancing out the 2 adjusters. This enables less stress on the tuner getting the setting perfect for you.  On our test bikes we ran the base adjuster on 10 clicks out and the FA on 16 clicks out.  Super plush with hold up straight off the bat!
• Not happy with the valving and initial setting installed for you from the spec sheet or your local tuner? Re work it out on the trail. This kit is super adjustable, soft to hard.  Base Clicker setting and base FA setting supplied.  
• All new valving/shim settings are available to suit all year model Xplor bikes. Got a 2017 bike? Upgrade to 2019 and now 2020 tested specs and setup easily. 3 base setting's are supplied

The KTM and Husqvarna  WP48 Air to spring conversion kit is aimed to suit all the range of KTM's and Husqvarna that come equipped with the WP48 AER fork as standard.  This includes Ktm's SXF, SX ,XC and XCF models as well as Husqvarna's equivalent bikes in the FC, TC,TX and FX range. 

If its got WP AER48 forks in your bike as OEM equipment , this kit will fit. No need to ever set air pressure again, transforming front end feel, corner entry and less pressure / spring rate variables whilst riding over long distance.

Install Video:

Our WP Air to spring conversion kit is a complete replacement cartridge assembly for your current WP AER setup.  It is designed to completely remove all the Air system from your current WP AER 48 fork  and replace it with a preload adjustable spring and cartridge setup.  High Quality German Engineered ‘Eibach’ Springs are available to suit varying rider weights.  Please advise upon order which spring you require (see recommendations below) or let us know your weight and speed  and we will recommend the best spring for you.

This kit fit's in minutes.  If you can pull down and service your fork seals on the WP AER 48 fork you can install this kit. Info and instruction included.

Spring Rate Recommendation 

 250F and 2 Strokes 

450F 

General riding & Motocross applications

These recommendations  are a guide only as fork Springs are weight and speed dependent. For example a 72 kg Pro rider falls into the 0.88kg/mm category but may well be better suited to a 0.92kg spring due to the much higher corner entry speed and the ability to hit large bumps at high speeds. Please note this guide is for rider weight ‘without’ gear.

Please note we have had great results using one spring down for Veteran/ C level riders on the 450 machines.  Eg. 90kg rider running a 0.96kg/mm spring for a plusher ride.

For more accurate advice please consult your local suspension tech or send us an email.

 Rider weight Spring Recommendation ( Pro Level riders may consider one rate harder than recommended due to the faster speed and need for 'hold up')

Key Features

• Never have to set your air pressure ever again.
• Much more reliable fork
• Super smooth action resulting from our tested spring guidance system. 
• Hydraulic Bottoming resistance using our tapered bottoming piston and seat.

Kit Fits : All KTM Xplor Shocks 2017-2020

After hours on the trail with our test bike and riders we have put together an upgrade for the hard fast acting KTM Xplor shock. After trying various valving settings initial plushness was not completely achieved until we installed a bleed circuit  into the compression pathway just like other opposition brand suspension have.

The XPLOR shock has no ‘give’ on very initial action and softening the valving or setting only resulted in wallow and blow out. Our shaft bleed mod comes with a new compression valve spacer , CNC machined ready to bolt straight onto the shock shaft (replacing the oem shaft spacer swap in / out).  A simple procedure to drill the new bleed circuit is then required (very easy to do with our supplied drill bit and instruction).  All valving is ready to go on and assembled as per shock building procedures.

Kit Includes :

• Complete Shock Valving / Shims 
  
• Bleed / Bypass post
• Drill bit for shock shaft modification
• Xplor Nitrogen Bladder Conversion
• Settings sheet including 3 valving setup options and shims to adjust.  Soft / Medium/ Firm 
• Instruction's

**Optional shims included to adjust to all 3 setup's. Medium setting is pre installed on both compression and rebound, allowing minor simple changes if required at all from our setting recommendation.   

Setting

1. Soft - Suits plush setting, absorbs all initial hits with ease.  We have great results with this with our Vet / Older riders that don't want to get beat up all day on long trail rides 
2. Medium - Average fitness, Average speed.  Great all round setting . A balance between soft and firm. Bump absorption with great hold up.
3. Firm - Ex Mx racer or fit/fast/tall guy riding on the trails at pace?  This setting works well for guys that like a firmer MX style feeling.  Rip hard fast Trail's ease.  Still not too firm but enough to charge hard. This setting was developed with our in house Vet MX racer after loving testing on the KTM EXC range.  

Shock Parts should be fitted by a competent suspension tuner or service shop 

Nitrogen Gas Bladder Conversion for WP Linkage shocks.

 Improved bump absorption and less fade.  Kit runs a genuine Showa Bladder for ease of re order and durability.

Fits :

KTM All 2016-20  SXF / XCF / XC / SX

Husqvarna    All 2016-20  FC / FX / TX / TC / FS   

Fits:

• KTM Xplor Shocks - ALL

Our Gas Bladder kit Converts your WP XPLOR shock to a Bladder nitrogen system allowing the shock to perform at a high 'Factory' Level.  The Oem Unit in these WP shocks have a floating piston standard that separates the oil and gas from mixing.  The issue with this while it is cheap to produce, generates heat and friction as the piston moves up and down along with the shocks movement when hitting bumps. 

We find a much better feeling and performance from this shock when it is changed to bladder system as found on the Factory WP Trax shock and all Japanese Showa/KYB units.  Making an already great WP shock better.

All Kits are Billet machined and supplied with Genuine KYB bladders internally for a high quality, ease of ordering spares and reassurance.  

Kit includes:

• Bladder Housing
• Circlip
• End cap ( nitrogen needle filled)
• Hex Screw for an extra backup gas Seal 

Kits Available to fit all Husqvarna TE/FE 2019-2020 Models.

All info and specifications and advise are supplied in the kit backed up with email support direct from Krooztune HQ.

Fork and Shock options are supplied in our Specification sheet with simple easy to follow tuning options for both Rebound and Compression.

Full Instructions to install both the Fork kit and the rear Bladder can be found here

All shock absorbers should be built with the usual shock building procedures. If in doubt leave this to a local qualified motorcycle mechanic or suspension builder. We offer an easy shipping service with in AUS to make this step a breeze. 

Kit Setting Soft - Medium - Firm 

                                      *Optional shims are included to adjust to all 3 setup's.

3 Setting Option - Fork and Shock 

1. Soft - Suits plush setting that absorbs all initial hits with ease. We have great results with this setting with our Vet / Older guys that dont want to get beat up all day on long rides. This setting is great for rocky terrain with square edge / tree roots hits.  
2. Medium - Average fitness, Average speed great all round setting . A balance between soft and firm. Bump absorption with great hold up.  A setting that is both initally plush and still holds up.  This setting is great combined with adjusting the FA adjuster to suit specific terrain.  Riding rocks? Click the FA out a few softer in seconds.  
3. Firm - Ex Mx racer or fit / fast / tall guy riding on the trails at pace?  This setting works well for guys that like a firmer mx style feeling.  Rip hard fast trail sections with ease.  Still not too firm but enough to charge hard.  We have tested our Trail setups on local MX tracks just to see what they can handle. Although the Offroad bikes felt a little heavier, slower and plusher than our MX race setups at the time of testing this,  we had a blast with embarrassingly fast 'FE' lap times compared to our laps on the setup Mxer's!

Compression and Rebound Selection Options - Build your Own Custom Setup

All our Husqvarna Shock and Fork setting and data are supplied with various rebound settings ( 4 different variants to choose from) to suit all spring rates.  Running OEM rebound damping on a stock oem shock for example will result in a super springy uncontrolled shock.  The OEM setting does not offer enough control or damping to control a much heavier spring rate.  

Choose a base compression setting from Soft/Medium/Firm and match it with the correct rebound in our specification sheet ( choose to match to your spring rate , info supplied) and you will have a superior rear end that is adjustable and controlled.  

Kit Includes :

• Xplor FA48 Flow Adjuster kit (inc specification / shims)
• Xact Linkage Shock  Setting and Shims
• Xact Nitrogen Bladder Kit
• Shaft Clamp tool 
• Settings sheet including 3 valving setup options and shims to adjust.  Soft - Medium - Firm

Our proven FA48 Mid Valve Assembly broken down to the main piece that controls the magic.  Adjusting shim float is done right here in this Mid Valve post assembly. 

This assembly works and adjusts well whilst using the OEM fork cap although changes are not as fine and controlled as when its paired to our Custom designed FA48 fork Cap.

Great adjustments at even better valvue.  The main issue with WP Xplor Forks right here.

This Assembly is very popular with Suspension Tuner's worldwide and installed alongside thier own idea's and setups.
