What happens when you change fork oil weight?
the down side to just running heavier weight (thicker) oil is that it is more prone to cavitation/aeration. used to be known as foaming. if you force a thicker oil through the same size hole (or stack) it will slow down the rebound damping, it will also stiffen the compression damping.
Do you need to replace front fork oil?
For this reason they retain their quality and viscosity for quite a long time. So when you regularly service your bikes, during then just keep a check on your front shock absorber performance.
Which is better light oil or heavy oil?
Light oil soaks up little bumps better but heavy oil is better for big knocks and helps prevent the forks from topping and bottoming out. Personal preference plays a big part with fork oil choice. Personally I stick to the stock weight but I also ride slower on dirt than your average nine year old, and then only on nice graded dirt roads. ymmv
What happens if I use too high viscosity of oil?
Just like using an oil with too high a viscosity may lead to problems in Josh’s engine, using an oil with too low a viscosity can have the same result. Oil that’s too thin can fail to develop a consistent lubricating film, inviting metal-to-metal contact that causes wear.

How much oil does a motorcycle fork take?
The Fork oil has its own SAE grading which ranges in the multiples of 5 (e.g. 5WT, 10WT, 15WT, 20WT). Higher the number, the better the load carrying capacity of that fork oil.

What kind of oil is in front forks?
Hence for that reason the front forks of the bike are filled with a highly viscous liquid, Fork Oil. Those who are not familiar with the term viscous or viscosity, it simply means the thickness of the liquid to provide proper lubrication as well as has load carrying capacity.
