Take the forks apart and replace the fork tubes with shorter ones or change to a different set of springs.

How can I harden up the front forks on my Honda 125 Varadero please


Measure the diameter of the springs top,cut pipe(Usually stainless steel)and remove the tops of the forks,install the spacers in each fork tube and enjoy-Experiement with the lengths,typically start with 1 1/2~3 inches.....You can also change the thickness of the fork oil...The tubed method does not require higher air pressure to work....

Front forks on a 1987 Honda Goldwing motorcycle how to change them


Place bike on center stand.
Jack the front of the bike to raise the front wheel off the ground. Be careful!!!
Remove the front wheel.
Remove the front fender and cross brace.
Disconnect the brake calipers from the forks.
Remove the air connections from the fork tops.
Loosen the fork leg clamp bolts on the triple tree.
Slide each leg out of the bike. Twisting while pulling often helps.
This can also be done without removing the front wheel but you will have to elevate the front of the bike another foot or so - just disconnect the air fittings and brake calipers, loosen the clamp bolts and drop the whole front assembly.

I need to know how much air to put in the front forks


Not sure what bike you have, I'm guessing it's an 80's bike if it's got air forks. Usually the air pressure is in the 5->10 psi range, you don't need much. Really try to avoid putting too much pressure in them. As well as making your suspension too stiff, it increases the chances of blowing a fork seal. Also higher the pressure inside your forks will increase the friction of your seals. Not a lot, but every little bit matters when it comes to forks.

This is a pretty simple explanation and I'm assuming the oil level in your forks is already correct. If it isn't then you will be able to make it a bit better with air but it will never be quite right.

I do not have a motor cycle manuel and I need to replace dust covers and seals and fork oil on a 750 GSX Suzuki 89/90 Model . have you ?


hi, the obviouse thing here is to get a manual, however if you think you have the finess required to do the job its fairly straight forward, put bike on stand, raise the front wheel of ground, remove spindle from front wheel, remove calipers from forks, DO NOT REMOVE BRAKE LINES FROM CALIPERS, once you have done this you can then remove the front wheel, put spindle back through loose wheel inc spacers to keep all in place, remove front mudguard, i always tell people to try and remove the lower fork leg first leaving fork tube on the bike, some forks it is poss to do this as the busshing is fitted to the lower leg and not the chrome tube, undo the bolt in the lower fork leg on the underneath inside where the spindle fits through, once removed, using a container to catch the oil, pull dovn on the lug to remove it, if it comes of all the way you are in luck easy job, the fork can then be cleaned and new seal fitted, the manual would come in handy for fork oil levels,if the leg does not come off you will have to remove the whole leg, before you remove it undo the top nut on each leg as the yokes will hold it for you, it is difficult to undo once the fork is removed, once removed, lift up the dust seal, remove the clip, and then the spring from the top, grip the lower leg in a vice with protective jaws, on the flat surface only, to grab the tube area would damage the fork leg, once in the vice, push in the stancion fully depress and pull out sharply you may have to repeat this sevral times useing the stancion as a hammer until the seal is removed, replace in reverse order,
DO 1 FORK FIRST REASEMBLE THEN DO THE OTHER, hope this helps feel free to contact me, paul

For the coolant where in the reservoir it says upper and lower , does this mean that when it's cold its at the lower and hot in the upper and also for the shocks does the number for the tension go from...


I always fill my coolant reservoir to the upper when it is cold. As long as it is between the marks your in good shape. I can' t answer your question on the shocks. I can tell you the higher the spring tension the harder it is to turn. Looking from the top rotating clockwise increases tension and counter clockwise decreases tension. Be sure to adjust the air pressure in the front forks to match the shock tension. Do this by bouncing on the seat and letting air out of the forks until the front and back of the bike drop together.

Fork oil spec


Fork oil can be from SAE5 to SAE 30 depending how hard you want the fork to rebound. The amount in each fork will differ by about 25-35cc, normally each for runs from 285cc to 355cc.
You can mix a lower SAE with a higher to get the SAe you wanted. Standard SAE used for fork oil is 10 which is equivalent to the thickness of DOT-3 car transmission oil. If good enough, please rate this free advise

How do you replace fork oil and what do you do with air valves on 1981 kawasaki kz650 csr front forks? Do you pour in new fork oil and then insert air through the air nozzle on each individual front fork?...


Your owners manual will help if you have one. There used to be drain plugs under each fork. The air valves help suspension smoothen the rides more.

How do you cahange front fork oil in a 2001 fxdx


raise front wheel .find socket head drain plugs @ bottom of lower legs.remove top nuts to add oil.CAUTION--top nuts are under pressure of fork springs. in the old days we would add a 1'' spacer to springs for a firmer ride.

Front fork seal is leaking


Yep, drain the fork oil, raise the front wheel in the air, remove the front wheel and axle. The nut to remove the lower leg is at the bottom, hidden by the axle. If it still leaks after seal replacement your fork tubes and lower leg sliders are worn out. Reassemble and remove the top fork cap. Pour in the correct cc of fork oil and ride.

The anti-dive valves are easy to remove...
Place the bike on her center stand, and raise the front wheel with a jack under the front of the engine/exhaust.
first loose the 3-way connector on the lower fork part ( brakefluid ).
Remove the 2 screws that hold the upper part of the anti-dive system to the lower part. You'll see the plunger. When braking, that plunger should move about 2mm out. It must be possuble to push it back in place with fingerpressure. Then that part of valve is OK. All the parts of the plunger are separately available by a Kawasaki dealer.
The lower part of the ADVS is also easy. Just remove the 2 screws holding them to the fork tubes. The fork oil will drip out...
When reassemble, dont forget to bleed the brake hoses at the top of the plungers...
To remove the springs...
Loose both screws on the upper fork clamps.
Remove the rubber stops on the air valves
Bleed the air out of the fork pushing the air valves ( some have only 1 air valve, and an equilibration tube just below the upper fork clamp )
Remove both fork spring stops. Caution, hold them firmly down while unscreing, to avoid the stops jump away at the end of the thread!
On reassembly, the stops must be screwed at 2.3 DaN/m (17 lbf/ft ).
The quantity of oil is exactly 348cm³ in each fork. Must be filled without the springs. Push then the fork several times up and down to pump the new oil in all the valves. Then with the fork down, measure the hight between oil level and top of fork. That must be 379mm.

Hope this all helps...
Don't know about an air valve at the bottom of fork tubes...
