Agreed, i think the previous owner changed the oil in the damper with a heavier one. The stock oil Suntour uses in their damper is a very thin clear oil almost like baby oil. anything over 5w is not advisable
Well, they would not give me the info on oil viscosity or the oil viscosity .I’m about 100% certain the damper never been open.. multiple comments agreeing that the fork is harsh. Been running a bunch of experiments changing and it just wildly changes.
Agreed it is very hard to find manuals for Suntour. M not sire if maybe Suntour has inconsistencies with the oil they use different batches. Just like you I also had to do a full break down and took note of everything and compared them to the fox. Also did experiments with fork oil and ended up using maxima plush 2.5w....oh and be careful with keeping the bike upside down...the damper seems to leak when the fork is upside down for a long time...this may cause an airlock
Hopefully my video stir the pot and then makes some. I have no clue why no repair manual. Some brands higher ones won’t release the repairman because I don’t want people screwing their stuff up.

Awesome video! I can tell that you enjoy the process of getting the most out of budget equipment
My friend's durolux38 r2c2 fork does not sound like that. I think the rc2 damper is Suntour's 2nd best damper.
У меня durolx 36 180mm нет такого звука. Тоже демпфер r2c2. Работает отлично не хуже zeb
Cheers
Do you use Rockshox foamrings or are they stock? In my Auron 35 there are very thin foam rings.
Any 35mm foam rings are fine
I feel my rc2 a little bit slow on rebound... How can i fix that? The fork is brand new
I ran it full fast you need to pull shims out of the stack
@@OtterMTBtechbut when you replace the factory oil with a 2.5 , It run a Little bit faster ?
Yes but the compression felt soft I’m re tuning a sun tour coil right now. Same issue
What type of oil and how much of it did you fill the air chamber?
No oil just grease
Very good video. But the oil in each bottle should not exceed 2 cc and not 10 ml. That is why it is causing that sound.
It knocked before. I think it was the o-ring on the air piston. Had same noise from a old fox
If you are a "cheapskate" don't buy Fox (branded) oil, buy Motorex. They are the same (in most cases).
Whatever brand you can check for low sulphur content synthetic oils...
🧐 is that the issues now? As far as causing havoc inside the the fork?
Im planning on buying can someone give an alternative that is also 38 mil stanchion
i used 2.5w oil and i feel like the damper isnt damping at all :S might try 5w
There is no instructions on what oil to use. Mine kinda did the same, but felt night and day different
U may be heavy for 2.5W, outside temperature also plays much
Why would they not provide the info at least in video form, what's up with that?
Hopefully my video stir the pot and then makes some. I have no clue why no repair manual. Some brands higher ones won’t release the repairman because I don’t want people screwing their stuff up.
I’d never buy a fork that sounds like that
It doesnt, its just his one that does that.
Tel your friend to jump on the fork on the pavement to check. It didn’t rattle to bad on the trail
