Have fun killing your forks

@@mountainbikemike actually I have to agree with @JK on that - oil bath are not recomended in SR froks

Yeah they say you can add 5-10cc to make it more progressive, but that's it.

i was gonna say this too. sr dont use oil in the lowers just the conpana grease they provide. I do put 8 cc on the air chamber tho.

Agree, SR Suntour Aion forks do not need the 25cc being shown in the video as confirmed by SR Suntour Customer Service.

There's not a true lockout. There will be a few mil of movement even completely 'locked out'

Probably it has something to do with the oil... Opened mine and put in hte damper side 60ml of 5w oil, lockout doesnt work so either it needs more oil or thicker oil... nevertheless i dont think it will damage anything, just the lockout needs more or other oil to lock itself

@@FotisVoutsas Suntour forks don't need oil to work. They are grease based.

@@DoctorORBiT then why mine cape factory with a crap ton of oil in the oil damper?? Even the lbs suggests oil in the damper side plus I run it about a day with no oil and it felt garbage and the lockout didnt work

Is it brand new? If it's definitely try to get warranty

@@Paulklampeeps It's out of warranty but the bike has only done 200kms. I pulled them apart and encased the spring in an old road bike inner tube. Seems to have done the trick. Shouldn't have to do this if they were correctly assembled and designed in the first instance.

2019 Clutch I have the same one

In Poland there is a proffesional service/shop that does this step as an upgrade for customers that wish to have it done. I suppose this means it doesn't leak. I saw the same oil weight used on another video, but uploader wasn't sure either and I haven't seen anywhere else any people that used such heavy weight oil for this purpose. I need to service mine too, and my notes say 2,5W oil, but it may apply to air chamber, as I'd prefer not to add oil to the bottom for quicker and cleaner service procedure. If service isn't a hassle everyone tends to do it more often. It's much better when you don't have a garage or a workshop -no risk of spillage. Most other forks use 15W oil in lower legs.

Just checked that shop which only sells and services Suntour forks and they carry Fuchs Titan Supergear 80W-90 and they describe it as air chamber oil for suntour forks. They also sell Fuchs Silkolene RSF 2,5W; 5W; 7,5W; 10W; 15W It's probably quite expensive and harder to get, but a really good one. If You're not very demanding user, any motorcycle fork oil of similar weight will be good. They can differ quite significantly between brands, cause of CST factor. WT is bullshit, CST is the real, comperable viscosity characteristic. Rarely on the label, normally available in pdf documentation from manufacturer website.

Yeah...just read that Aion does not have seal in air side lower leg, Auron does. So this might leak, not sure.

Did you solve it? As?

@@janochavez I've got 80w90 oil in my Aion, and it doesn't leak. I've assembled the bottom with a bit of grease tho, so it might help with sealing.

80w like he used for the seals. You can also add a little in the lowers (5-10 cc) to make it more progressive, but don't add more than that. Suntour forks rely on the grease and don't have oil baths like Rockshox and Fox.

@@CodyKing oil in the lowers has nothing to do with progressivity, oil in the air chamber does

@@CodyKing 80w is for air chamber only as its to thick. Use 10w suspension fluid.

Yes, 15w40 Mannol Dexron 3 ATF!

You can add some Teflon tape to the top cap threads or if it's leaking from the valve, you should replace the valve core, you'll need a valve core remover for this.

100psi is insane!

You are supposed to have 5 ml or so of hear oil in there which should stop any air loss

@@jondotcom8706 that's what i was about to say

@@jondotcom8706 Where do you add the oil?

again, there is a bunch of oil in there. should you not put some back? If it was only! grease none would be all over my floor.

sr suntour air forks don't take oil in the lowers. That's one of the distinct characteristics of suntour that separates them from rockshox or fox. They claim is easier to service the forks by just using grease in the lowers and maybe like u said 4 c of gear oil in the o rings and seals

@@renenavarro4121 totally agree with you though I found to much sticktion even a week after service, they do run smoother with oil though the aions have foam rings soaked in oil.

@@darrencardy2119 do you know whats a good fork oil to soak up the foam rings?

@@renenavarro4121 there's plenty out there but I use WPL suspension fluid 10w for my aions.

@@darrencardy2119 cool I have aions too the 35 evo pcs. Recently upgraded the negative spring and the cartridge. Feels super plush. I had the remote lock out damper which didn't have much tunning options
