Hi, I’ve just posted this but it doesn’t seem to have posted, i’m sorry if i’m posting this in the wrong section or doing something wrong.
I’ve just got my bike running today and i have 2 hoses lose and there is a port on the airbox which had the reminants of an old hose.
What was that connected to originally? at the moment the two hoses that are lose seem to be the vent from the carbs and the vent from the tank. still have to get the bike running right but thought i’d start with the basics in case I have a hose disconnected.Thank you for your help.

Any pictures please?
Close up ones and also distance yourself away from the bike a little so i can see with a bird eye view but i believe with the 2 tutorials on this site, check your self they are routed well.
Search “Air Vacuum” and “Fuel Line” tutorials.Extra hoses will be a tank overflow that’s directly under the tank away from the tap , also EGR system (bypass it & get the extra blanks we sell at the shop if it needs more! – Some engine have twin EGR system (aka Secondary Air System Korea calls them officially) )
Just make sure the airbox is “blanked” from extra hoses coming out of it to the EGR

Hi, thank you! Sorry for the duplicate post earlier. Hopefully i can send this reply now.
I have only had a few minutes today to take these but i’ve outlined them using my screenshot editor to show you what i am reffering to.
This is the tank with the vent attached but the fuel line is still on the bike. that clip on the hose was put there by my uncle yesterday as he was the one that pulled off the hose and threw it on this hose for somewhere to put it so it didn’t get lost.
This is the port in the airfilter housing that had that clip and the crumbling remains of a hose
this is the loose pipe from the left side of the carbs, i suspect this is the pipe that originally went to the airfilter housing but just making sure in case it’s not something vaccum related.
I will be blanking off the AIS once it’s passed its’ MOT, I’ve already ordered the parts to do it, it’s a little way off before I do though being that I need to do a sproket and chain set and sort the brakes out first.
Once i’ve done that I will be balancing the carbs as well (i’ll do a guide if there’s interest).Thanks Marcel 🙂

There is always a silent grateful majority who like tutorials , thats why they keep coming back we even had some mechanics actually tell us the clutch tutorials were helpful to them in the past, we know that most UK garages don’t really want to touch Hyosungs which is a shame!
They run great when its all working well and it shows its mood too.
I am digressing, so let me address your pics now
You can block this pipe, as it goes nowhere. So make sure that side-mounted air filbox doesn’t leak air elsewhere too!
This actually goes straight to the ground (road), (breather hose)
If it is the hose that’s connected directly to the tank and its far away from the tap so to speak.That is carb float bowl – overflow to the road.
– If your floats burst / jam = it drains straight out to avoid flooding carb.
– if the bike falls heaven forbid , then it pours all of it out (well most) -
When I was younger I used to follow a lot of guides online for stuff and they were an absolute blessing for stuff that isn’t exactly obvious, I try to share what I know when i can because of that. Yes there’s a small shop here that does repairs on them and i think anything bigger will just ignore the hyosungs because parts and support is practically non-existant to them. It is a shame. Even simple oil changes are often not done by them (and the one that did, overfilled my bike too as it turns out, lucky it was a garaging service rather than a running one)
Oh fantastic! Thank you. That’s what I thought they were but my uncle said to make sure and i’m not that skilled, i can only rely on what i’ve read. I will block that port on the air filter and route those other 2 hoses out under the bike.
Thank you for your help 🙂

That is just appaling!
Owner’s manuals still exist on the internet, can i shame them?!-
I’d say yes as the garage I went was actually a honda garage and they should have known better but they shut shop just before the pandemic.
To be honest, all motorcycle garages here are terrible. they’ve all bodged something up and facebook is filled with stories even with common bikes. I think as a rule most just work on their own bikes here. plus 82 quid an hour isn’t worth it to install 2 plugs, throw some pads on and a put some oil in.

WHAT!!!!!
82 quid per hour! for 2 plugs ?
Sorry but you will get a wayyyy more premium service with us for way less.
Yikes!
I will send your goods soon, but bare with me for extra 2 working days , i think we just had in influx of EGR blank orders, so gonna ring supply chain to send a big box again 🙂 , when you get the usual “dispatch” email, it means goods are with your postie 🙂

There’s only the one big motorcycle workshop here so I think it’s lack of competition locally, I’m certainly not using them again.
My other bike that I’m working into (an XVS650) is having a bit of work done before I get it and they are charging that for a couple of seals, re-grease the brake pins and sticky switches. I suspect a standard service would be the same. The place i got it from were also surprised at the cost of it as well but can’t be helped as it is needing an MOT.Yes easily!, when my gv is riding i’ll book something in for a lookover 🙂
Thanks for letting me know, My uncle and I have just recently pulled the rear wheel off to do the chain but it turns out we’ll need a socket, all the ones he had are either too big or too small haha.
Off the top of your head you wouldn’t happen to know the torque specs for them would you? I can’t find a GV service manual, just the owners manual.
Thanks Marcel 🙂

GV Rear Axle should be 22mm and 21mm nut , but also get 20mm and 23mm as Korea did change the axles even on their bigger GV bikes.
Torque Specs for rear axle bar = About 60-70ft lbs max (Use 50-60ft lbs & double check its safe) use online converters of FT LBS TO NM if your torque wench doesn’t show FT LBS markings.
