Title: Front Fork Oil Level
Post by: Yohji on November 19, 2015, 05:57:55 PM
In garage setup, Front Suspension, Oil Level setteing, effecting is reverse.
In Normally, Oil Level to up (ex, 100mm → 120mm)(less air in fork), suspension to harder in stroke. and level to low (100mm → 80mm)(more air in fork), suspension to softer in stroke.

but In GPbikes. Oil level up cause suspension to softer... Is it not bug? ???

Or Will my interpretation is wrong?

The question can only be answered by Piboso.
Does Oil 140mm mean the amount of oil in the fork or does it mean the size of the air gap?
(The smaller your air gap (the more oil you put in the fork) the harder the fork becomes towards the end of the stroke -  That´s what you have found)
I believe that the air gap is meant by "Oil 140mm".
200mm -> softer
140mm -> harder

Once PiBoso has the gameplay and core issues sorted i think the garage is an area that needs some attention especially to appeal to a wider audience of casual players.

I have been trying to get my head around the bump and rebound setting and i am still not completely sure how exactly if effects the bike. I take all the rebound off and the bike seems more settled add rebound damping and i get oscillations - seems back to front  ???.

A better graphical representation (maybe sliders on a graph type thing) of what is happening would be nice, a picture really is worth a thousand words

+1 as i mentioned before... there should be a bike image next to the slider in which you can see the difference. It would be much easier to see whats happening. Preload, air gap, softer-, harder springs, rake angle, swingarm lenght and pivot should be "easy" to animate i think. Bump and rebound is harder and should be pointed out in MaX Telemetry i think. Also, someone pointed out the fact to change the position of the yokes to adjust the front high "more effective" ..

The measure in the garage is the level of the air in the forks.

@Piboso
Thank you for the confirmation  ;D

Wow confusing....  ;D

So, Oil 80mm - less air, more oil = stiffer.

      Oil 140mm - more air, less oil = softer.

Programmers always tend have a weird way of thinking about things. Lol.  ;D

But yes it is rather confusing considering the setting indicates "Oil" level in the forks; would hope Piboso would simply change the name to "Air" level unless he wants to reverse the logic in the code?  ;)

Thanks for letting us know Piboso.  ;) 8)

well this annoys me a bit to be honest.. past couple of years (maybe more  :o) iv'e been doing it all wrong...  ::)

already suspicious about the preload..

pivot on stock bikes dont work..

Oil level is actually the Air level  ::)

What else?

Sort of makes sense, when you set up the fork you measure from the top of the tube down to the oil

Bigger number=more air

Not as confusing as the engine braking setting  ??? Which i discovered today !

Roll on B8, really starting to notice its like riding different bikes depending whether your riding uphill or downhill or on the flat.

yeah i guess it makes sense now but...

haha yeah less is more with the engine braking..

took me a while to notice that rebound setting is.. 0 = fast rebound. Again its pretty obvious now but its all a guessing game.

would be nice if piboso or somebody could just confirm all the garage settings.

Agree, I have often thought some of the settings seem to be in reverse but have only mentioned it a couple of times, convinced I had had one too many mushrooms.

Programmers having a weird way of thinking about things..... Surely you must have heard this in the past Piboso? If not I'd be surprised. That's what makes programmers good at what they do because they think in a very logical and literal way, something most of us are not used to doing to the degree programmers do naturally. So I don't say this in a disrespectful way at all. In fact it is a compliment.  :)

Oil Measurement: Okay... I see the point and stand corrected; I apologise for my misunderstanding.  ;) 8)

However I'm sure you can also see that having the word "Oil" and then an adjustment in "mm's"  is confusing to the uninitiated in fork mechanics and therefore would possible benefit by a more graphical representation in a latter garage UI update?  :)

In all service manuals for bikes the front fork oil level is stated as in GPB.
e.g.
Oil level 135 mm (5.31 in) ?
<Min.~Max.> 80~140 mm (3.15~5.51 in) ?
(From top of outer tube with inner tube
and damper rod fully compressed
without spring.)

Think that should be copied and pinned in a support section "Guide To Setups". As we learn other stuff it could be added too. I really think that would be a helpful idea. ???

One thing that would help people is having tooltips popping up when you mouse-over settings.
For fork oil: "Oil level: higher = less oil = softer, lower = more oil = stiffer".
Same for the other settings (where needed, e.g. Engine Brake).

+1 that Max - a guide needs to be found - pop-ups don't. The guide could have videos though for the short of cells like me.
