So Paaji, is your fork action smooth?
I could understand that 190ml occupies about 8" in the fork tube but then what is the right amount?
Fork is smooth. What weight fork oil did you use ?
I have tried 5W, 7.5W and 10W fork oils. 5W is too thin and front dives too much. 10W is heavier and pretty good for most riders. Some people prefer even stiffer fork and use 15W or 20W fork oils. Heavier/stiffer oil is preferred for riding on smooth twisty roads. Lighter oil is better for bumpy straight roads. Too light not good, too heavy not good.
Same goes for volume. Some have tried 200 ml and others more 230 ml or 250 ml. As long as oil level reaches minimum level to do its job it is good enough to go. Too much oil will tend to spill out. Somewhere between min and max will be fine. Too little will not do a good job and too much will cause leaks.
You decide what is right for you, your riding conditions, style, weight.....
.
Using 190ml, the oil level reaches 16" from the bottom tip of fork
(about 9"+7" in picture) .
PS - High tire pressure will give bumpy ride.
