SOURCE: 2000 yz125 kickstart spring is broken

Not sure of anything aftermarket. You drain the oil, remove the right side and there is the spring. You will need a new gasket, it really isn't very difficult.

SOURCE: Yamaha xj 900 s Front fork oil amount in cm

The forks hold 286ml or 9.67 US OZ of oil, best would be to use hydraulic oil.
Good Luck.

Change your fork oil to something more suited to your driving style. Those forks may be feeling tired, but they works nearly as hard as your valves. The oil has most likely broken down and needs replacement anyway. Do some shopping and ask the experts what is best for your cruising preferences, If you need a stiffer or softer ride try inserting a new set of springs. Remember coil windings as well as fork oil determine the cushion in your ride.

How do you service and adjust the front fork suspension... Way stiff!!


Fork adjustment varies from bike to bike. Some have no adjustment at all, some have screws that you turn in and out, some are adjusted/aided by air. Some people change the weight (viscosity) of the fork oil, fit firmer or looser springs etc. Fork adjustment and settings depend on the riders size, handling and bike style so there really is no "stock setting, one size fits all".
What you consider way stiff may be ideal for me but too soft for someone else.
The best way to find out how to adjust the settings (if it is possible) is find a forum online relating to your bike as adjustments of this sort is a fairly hot topic of discussion.
I hope that is of some help.

What is the recommended oil for forks on the 1996 honda magna


depending on your weight and the type of riding you do its kind of a loaded question, normal fork oil will range from 5 to 20wt so depending on what your tipping the scales at lets just say the bigger the rider, the thicker the oil, now next question is what type of rider are you? mountain pass riding or just straight down the highway? have you had any problems with bottoming out at all? if so go with the heavy wt but also consider either shimming the stock springs or just replacing with an aftermarket spring kit. if your into just floating down the interstate then my friend keep it on the lite side.

Correct quantity(ml) of oil per front shock(fork) for 2003 Suzuki RM250


110mm oil height in each fork tube. Remember to bleed it first to ensure all air is out the inner chamber and then measure 110mm from the top of the tube, fully compressed with no spring or damping rod inside. USe a 5W fork oil. You can also look at WWW.RACETECH.com under search, and then valving search, enter all your relevant details and bike model and it calculates it for you.

Fork oil level: 2006 KDX 200


This all depends on what size forks you have, but a good rule of thumb is 120ml. After that then what you want to do is to ride the bike and make adjustments to your front end until your liking.
