[Tutorial] How to Change Oil & Filter on Hyosung GV + GT125/250 +R

Time for an oil change? …One of the crucial things to stay on top of!

This short tutorial shows you how to change your oil with ease on the 125/250 twins (2001-2018) and also the filter!

This applies to: GV125 (01-2018) / GV250 (upto 2018) / GT & GTR 125 (03-2018) including GT250+R.

Personally, one of my other twins gets its oil changed every 1,000-1500 miles using Ester oils. Manual suggests longer intervals, but I prefer premium oil (JASO MA2, Ester good) every 1500 miles max. 🏍️

Moving on, let’s prepare the parts & tools first…

Oil – 2x 1L Bottles
(Bike needs 1.5L total)		 Oil Filter & O-Rings
(don’t skip filters!)		 Drain Pan/Bucket
(3L+ capacity)
Torque Wrench
(too crucial, you’ll see why below ⏬)		 Size 15/17mm Socket
(12 sided, NO SPANNER)		 Size 10mm Socket / Driver

Plus these bits also: Pliers | Funnel | Gloves | Clean rags | Measuring jug

1. Undo your filler cap first!

For stock caps, use pliers (anti-clockwise). For custom CNC Caps, use 19/21mm socket.

2. Go under engine & loosen the drain plug

For GTR owners, use a bar extension or remove fairings. ⚠ Be slow to prevent the plug falling into the bucket!

3. About those drain plugs…

Roads are salty; stock plugs can seize. Use a coloured, weather-resistant magnetic plug to avoid issues. Available here.

4. Finished draining? Close the drain-hole!

Clean under the engine, use torque wrench max 15ft lbs. ⛔ DO NOT OVERTIGHTEN THIS BOLT.


5. Go to your oil filter cover next!

Undo the 3 nuts holding the cover. ⚠ Oil WILL fall out; place a rag/pan underneath. Wear gloves. Dispose old filter.


6. Filter Cover Inspection & O-Ring Change (Pt.1)

Clean the cover, check spring, replace big O-ring (dress in oil first ⛔).


7. O-Ring Change (Part2)

Replace the O-ring at the back inside the filter area. ⚠ Use a small hook, don’t force. CHANGE THE OLD O-RING TO A FRESH ONE.

8. Next, your new oil filter goes in!

Ensure the hole of the filter goes inside the engine as shown.

9. Close the filter cover!

Tighten nuts to 6 ft lbs max. 🚦 Ensure the cover O-ring is oiled.

10. Done? Grab your oil (& measuring jug!)

Pour 1.5L (1500ml). Not less, not more 😉 No jug? Use bottle markers.

11. Get your Funnel and pour the oil in…

12. Close the oil filler cap!

Ensure cap and O-ring are clean and undamaged.

🚦 Complete – Idle for 60 seconds & turn off!

Check sight glass, top-up if needed, and ensure drain plug is secure.

Tidy up & Go ride. 🏁

[Tutorial] How to adjust Carb Slide Needle (Tuning) – Hyosung GV & GT 125/250

[Tutorial] How to adjust Carb Slide Needle (Tuning) - Hyosung GV & GT 125/250
How to adjust/tune the carburettor slide needle for improved riding…

⚙ What does this do?

This modification allows the bike to reach better cruising speeds via slide needle adjustments. The throttle slide needle controls main jet fuelling as revs change. This also eliminates flat spots between 4k–7k rpm, common on 125s. For example, if the bike struggles at near full throttle, this mod helps it pull with less twist. Your bike should run better from 1st to 5th gear.

👇 Before we start, this tutorial assumes:

  • You will do this at your own risk and without rushing.
  • You have good spark plugs (e.g., Platinums) or older IX plugs.
  • Your ignition coils & HT caps are sparking well.
  • Your carb has already been upjetted (tap here…).
  • You have a performance filter (K&N, BMC, etc.), or if using a stock cotton one, cut its snorkel.

Tools needed:

  • JIS type screwdriver (+ Philips style)
  • Large & long flat head screwdriver
  • Size 7mm socket (front bolts sometimes hex shaped)
  • Watchmaker flat screwdriver
  • Clean microfibre cloth

1. Go to the right side of your bike

Spend most of your time here. Work on one pot at a time and avoid distractions.

2. Unscrew the 1st diaphragm cover

Remove the 4 bolts holding the diaphragm cover.

⚠ Disconnect throttle cable!


3. Remove the spring & diaphragm

Gently remove piston slide & spring.

4. Inspect & clean parts carefully

Use Wynns Carb Cleaner for all parts including diaphragm cover. This prevents sticking between revs/gears & scoring internal carb walls.

5. Unscrew plastic plug holding needle

Use long flat blade screwdriver, gentle ⚠.


6. Remember the order of re-fitting

Keep the image in mind when refitting small parts.

7. Remove the E-Ring (Circlip) slowly

Use a small watchmaker screwdriver. ⚠ Handle gently.


8A. Needle grooves

  • Pointy end of needle faces down
  • Push down black spacer slightly
  • Put E-Ring in 3rd groove
  • Push black spacer back against E-Ring


8B. Another view

Ensure E-Ring is in 3rd notch with black spacer pushed back. (Lowest groove, pointy end down. Factory usually 2nd or top near flat end.)

9A. Check throttle slide hole

9B. Grab needle & follow image

9C. Slot needle & mini-spring

⚠ Review step #6 and 9A/B

10. Check needle for free movement

10B. Coat throttle slide ring with oil

Prevents leaks & particle trapping.


11. Refit slide, spring & cover
  • Reconnect throttle cable
  • Ensure 4 screws are finger tight
  • Finished? Move to next cover.

12. Repeat on rear carb

13. Final check 🏁

  • Airbox clamps tight
  • Slide cover bolts finger tight (x8)
  • Throttle & choke cables checked
  • Air lines secure (prevent vacuum leaks)

Done!

Straightforward process. If unsure, comment. Otherwise, go ride! 🏁

FAQ / Troubleshooting 🎳
  • Bike runs worse after mod? Check covers & airbox for leaks.
  • No air leaks but still worse? Inspect spark plugs; ensure better sparking than stock.
  • New plugs but still worse? Check HT Cap & ignition coils. HT Cap removed ≈ 6kΩ; Coil ≤6kΩ to frame.
  • HT cap/coils high resistance? Replace both; stock ignition parts can’t be repaired.
  • Changed coils/HT caps but still worse? Ensure main & pilot jets are clean. Tap here to remove carbs.
  • Can this be done on stock 125cc? Mod will slightly enrich mid-range; jetting & better electrics improve results.

💡 Tips:

Replace the O-rings every time you remove manifolds to prevent air leaks. Always work in a clean environment as intake holes are exposed. We sell the O-rings in the shop!

For less stress, use stainless steel socket cap (Allen key head) bolts with a good CRV Allen key and tighten properly. Form A M6 stainless steel washers are recommended. In the UK, these are widely available at car shops including Halfords.

How to change Vacuum Lines on Hyosung GT125R GT250R & GT Comet (Air Hose Diagram)

Hyosung vacuum line setup

Changing the vacuum lines on carburetor 125/250 vTwins should be fairly easy. All you need is 15–30 mins of your time. Let’s start with the basics.

  • Hyosung advises that if your factory lines are 2–4 years old, discard them regardless.
  • Old pipes can rot internally, especially cheap Chinese rubber ones.
  • Larger, colder air pipes can improve the vacuum system, but use strong clips!
  • Strong clips are essential to prevent air leaks.
  • This tutorial applies to all carb-operated 125/250 GT & GTR Twins (including GV125)

Let’s go now… strip your fairings (GTR owners)

(Naked bikes can skip this step)

That’s it – Vacuum setup is done! 🚦

If you have an AIS device (Fake emissions/EGR), see below:

  • Refer to the cartoon diagram of the “EGR DELETE” mod.
  • Remove or block anything feeding it.
  • Example image below shows setup. Personally, it’s a useless device.
  • If you want it connected, replace “blocked” with “connected”.

I hope this quick tutorial was easy to follow. If you get stuck or need help, just comment on this post! This also applies to GV owners since they use the same rear pump.

How to upgrade Fuel Lines & Filter on Hyosung GT125R GT250R (Carb Hose Diagram)

Hyosung Gt125r fuel lines diagram filter hose

New Fuel Lines? Let’s cut to the chase… (No pun intended!)

This guide shows how to replace your stock lines with larger uprated braided ones.

Note: If your stock/original fuel lines are 2–4 years old, you must change them, as per the service manual.

A. *️⃣ Pros & Cons of braided/fresh lines vs old stock lines

  • Larger fuel filters (3× size) benefit from gravity assist & a cleaner reserve. These filters last roughly 15–20k miles (except cheap Chinese copies).
  • Braided hoses last longer & are more heat-resistant than standard lines (40–100°C).
  • Bigger lines allow fuel to reach the carbs faster, improving response.
  • More fuel slightly improves throttle response. (Hint: Aftermarket exhausts may give a slightly deeper note.)
  • If you have upgraded carb jets, larger lines help.
  • Cons: None.

Be warned: Cheap Chinese fuel lines may fail within 1–2 years and risk leaks on a hot engine!

B. 🏍 Compatible Bikes

  • All carbureted GT125R & GT250R models (Carbs = large silver components between the v-twin engines)
  • Naked GT Comet bikes (Unsure? Comment on this topic!)

C. 🔧 Tools Required

  • Cutting tool & flat (-) screwdriver
  • 10mm / 12mm spanner or socket
  • Stubby / short (+) screwdriver
  • Clean cloth or towel

🚧 DISCLAIMER: Work in a well-ventilated area or outdoors. Fuel vapors are flammable!
Follow this guide at your own competence. Custom parts may void warranty on new bikes! 🚧

1. Remove the fuel tank

  • Use a 10/12mm spanner or socket to remove the bolt securing the tank to the frame.
  • Disconnect the 2 pipes under the tank.

[Bike Mod] 650/250/125 – AiS Block Off Removal (EGR Delete)

HYOSUNG PDF MANUAL AIS REMOVAL DELETE EGR MOD MODS

⚠ WARNING: This guide involves AIS (EGR) removal. Follow at your own risk! Incorrect modifications can damage your bike or void warranties. Make sure you understand the steps fully before attempting.

Credits: I did not write this, but full credit to the lad who created this book. (BTW, follow at your own risk!)

Benefits & Proofs

Aimed at 650cc bikes but the same method also applies to smaller CC bikes.

Deleting the AIS (EGR block) from the bike results in:

  • Loud pops on the exhaust pipes
  • Deeper groans on idle (louder induction roar)
  • Improved performance from 4-7k rpm, especially for low CC bikes
  • Recommended for stainless pipes anyway
  • First step race teams take—removing parasitic parts
  • Overall marginally louder bike

What is AIS? (Often incorrectly called EGR by uneducated mechanics)

  • It makes the bike “fake” its emissions by burning cleaner air to meet Euro laws.

That’s it!

  • It has never proven to benefit bikes; it actually “steals” energy from the engine. Think of it like a “Remora” fish under a shark, migrating across the seas 😉

HYOSUNG GV 125 250 CLUTCH PLATES uk hysoung FORUM OWNERS CLUB

⚠ Symptoms / Troubleshooting Hints

Always replace your clutch plates when you notice the following:

  • Every 5000-6000 miles. Regardless (just like brake pads have a wear limit!)
  • When you find yourself adjusting the clutch cable frequently.
  • When gears feel notchy or hard to shift.
  • When the bike slips during gear changes.
  • Does your clutch basket “knock” during idle?
  • Does the bike “rumble” when holding the clutch lever in?
  • Acceleration is slower than before.
  • Clutch seems to “slip” on hard acceleration.

🔧 Let’s fix it….

Technical Inspection (What to look for inside)

HYOSUNG GV 125 250 CLUTCH PLATES uk hysoung FORUM OWNERS CLUB

  • Clutch Plate Thickness Limit = 2.6mm (New ones range from 3-4mm)
  • Clutch Spring Free Length Limit = 36.2mm (Normal range 3.8 to 4.6mm)
  • Deep grooves on the clutch basket? Time to replace entirely, or file gently if minimal wear.
  • Silver clutch metal discs (separators) – 1mm distortion limit.
  • Loud rattling sounds? Your clutch plates may be cracked and must be replaced immediately to avoid blocking oil passages.
  • Clutch basket center nut must remain tight with its washer intact.

🚦 Let’s begin!!!

HYOSUNG GV 125 250 CLUTCH PLATES uk hysoung FORUM OWNERS CLUB

Park your bike, get your tools out, and start with the drain pan to drain oil first…

HYOSUNG GV 125 250 CLUTCH PLATES uk hysoung FORUM OWNERS CLUB

  1. Use either 15mm, 17mm, or 19mm socket to drain the oil:

    • A. Clean the oil drain plug.
    • B. Drain all the oil completely.
    • C. Refit the plug.
    • D. Tighten to a maximum of 15 ft.lbs (20 N.M) – torque wrench recommended. If unavailable, tighten until it feels snug.
🔥 BE WARNED! – THIS IS THE “DRAIN” PLUG (DO NOT UNDO ANYTHING ELSE UNDER THE BIKE)

Drain plug warning

Ready? Get the new clutch plates and discs out…

New clutch plates ready

Remove the engine cover bolts in the blue circles. Remember where each bolt goes! Some bolts vary in size. 🔥 Be warned: leftover oil will spill out!

Oil filter warning

When you reach the oil filter rod, carefully remove it:

  1. Put two nuts on top of each other.
  2. Undo the second nut (the top one acts as a stopper).
  3. Continue unscrewing until the rod comes out entirely.

⚠ Note: Mole grips can be used with caution but may scratch the rod.

O-Rings warning

Don’t lose the O-Rings! There are 2: one for the cap, one inside the oil filter hole. Always replace O-rings & filter during oil or clutch work.

Clutch cover removal

Use a stubby screwdriver to gently loosen the clutch cover, working from the bottom and then top near the oil cooler pipes. Carefully remove the cover.

Gasket warning

🔥 NOTE: The gasket must be replaced with a new one. Old gaskets may tear.

Remove clutch bolts

Remove clutch bolts from top down gradually (25% each), then fully remove. This protects the clutch springs.

Inspect clutch hub

  • Remove the front clutch hub facia plate and inspect underlying parts.

Diagram

Inspect parts #10, #16, #17, #13 on the diagram.

Remove plates

Remove clutch plates one by one, remembering the order: First and last plates are always fibre. Steel discs go in between.

Plate order diagram

Fit back parts in this order: #13 → 17 → 16 → 9 → 10

Tightening sequence

Re-tighten clutch bolts: Start top 25%, then bottom left & right 25%, then remaining bolts to full torque. Max torque for clutch bolts = 5 ft.lbs (finger tight!).

Final steps

  • Max torque for clutch engine cover bolts: 5.5 ft.lbs (aluminium)
  • Use fresh oil, O-rings, filter, and gasket
  • Record this event in a log or back of owner’s manual to track mileage and service history

👍 Recommendation: Use high-quality 10W40 or 10W50 JASO MA2 ester oil. Avoid low-quality brands; Motul & Silkolene are best.
