Aug 12, 2026 at 6:43 AM #23285Bike Model = : GV650
Hi Guys,
I have (2013 Model) GV650 Hyosung which has done nearly 24k in last 3 years. The first downward gear is very noisy and makes a lot of noise when pushing down as if the clutch doesn’t work, but the rest if the gears work perfectly.
Secondly, the Engine Oil level indicator has become totally black. What is the procedure to clean it?
Lastly, after how many kilometers do I have to grease the wheel hub bearings, if I am riding in normal city conditions in Australia?
All opinions and suggestions are welcome. Thanks.

What exact oil are you running ? and do you have a picture or link for it ? also can you advise the last time the bike had its bearings changed out ?
Normally good bearings should have a double seal on each side of them (not metal seals) but the rubber seals built inside the actual bearing itself should keep it self-greased unless they are just due a replacement if the previous owner has put cheap ones in.
Pull the wheels out and look at the bearing codes, take a picture and go to any motorcycle shop locally and ask for replacement bearings for the wheels that match the codes you see on them, they should offer better rubber sealed ones (they will be self-greased inside) so you can swap and go.

Hi
I am using 10W40 which is the recommended Engine Oil on the Bike.
As far as the bearings are concerned, it looks like it has the original wheel bearings on it and they have never been changed. I was just wondering what the normal life on the bearings is and when do they need replacement.
I am also looking for a mounted Video camera for my bike while riding. Which brand and model would you recommend. Thanks

I used to use GHOST Drift cams and their little stick-on adhesive pads you an mount to the bike fairing if you want a bike view or helmet mount.
I heard GoPro must be better these days , i have not tried other brands personally, so its a matter of research maybe the top 5 camera companies used by Skiers or ATV riders, if these cams can survive harsh enviroments, they should be good for the street use. The design / looks is of the beholder 😉
I mean specific oil brand , some oil is cheap and doesn’t really help the motor but the service manual says if the bike is a daily rider or used heavily then use “Premium” oil.
I personally use Motul 7100 , i think it’s best oil for Hyosungs , compared to the likes of Castrol. Another good Ester grade oil is Sikolene Pro 4 or Comp 4
A good oil can influence how slick your gearbox and clutch is , and how long it lasts before it “shears” off (getting useless around the bike)
10K on KBC bearings is my guess but i always changed them as in the past i had an annoying experience with the sprocket drum wobbling / grumbling before the bike hit 8,000 miles. When i switched to better ones, everything rolled smoother and had to be double sealed bearing rubber sides. Never was a fan of bearings with metal shields on the sides.
These are my thoughts so far. Hope they are useful!

I really appreciate your feedback and experienced solutions.
I will do some research into the Cameras and see which one would be a best compared to the cost benefit analysis.
The issues is that the electronic gadgets market is very fast paced and the older models get outdated very quickly.
It is hard to choose when the technological innovations are moving at such a fast pace.
I will also check if I can find the bearings locally, as we do not have any Hyosung dealers in Australia.
Or I will have to get them from Korea as I did with the spare parts earlier.
Thanks. Terrey
