Bike Model = : Hyosung GT250 GT125 GV250
Anyone know the size of the Valve Oil SEALS? (diameter of top hole, bottom hole & height would be great).
And what tools did you use to remove your Valves on a GT250 or GT125, etc?
Valve Remover? Or did you use sockets of the same diameter socket to knock the valve retainers out?
Cheers.

The service manual from the GT650 section has the information on seals and tools used to remove valves. You would measure your old ones if local dealer isn’t there?
GT250 uses the 650cc seals. Can’t remember the size of my head, as its not something i rarely check to be fair.

Marcel the manual is not going to tell me to buy a Hyosung Valve Tensioner is it? I gave up looking for one.
I thought the shop sold the valve oil seals & hoped you’d have one handy. 🙂
How did you guys remove & replace your valves. A link to a valve tensioner that worked on a hyosung would help a lot.
Removal can be done with sockets i think but if anyone knows the best tool for the job, i’d like to know it please.

You can get valve compression tools that cover all sorts of size valves for only a few quid which will do the job Quote
Thank you Simon. Bought a Valve Spring Compression Tool Kit. Won’t know if it works until i try it, which is not the way i like to start the job. Bought a FULL Cylinder/Piston kit but it never arrived. So i bought the parts individually. Will be the 2nd time i’ve done my clinders & pistons – i honed the old cylinders but they’re not perfect.
Bought a Piston Kit, a rear Cylinder, Head & Cylinder Gaskets, Intake & Exhaust Valves, Valve Oil Seals & Valve Collets. All i need is a Front Cylinder & possibly a new set of Valve Springs.

Valves, Oil Seals, Collets:
