Hi, Andrew I would love to help you with your engine or chassis noise but I just loaned my brand new pair of listening ears to your local dealer's chief technician so he could take your bike for a test ride and give you his professional opinion and estimate about your noise and repair cost. If you are a little short on "DRACHMA" and a Dealership is not on your list of fun places to visit then perhaps the list below will help soothe your worried mind so you can make an informed decision.

2. Belts---CHIRP

Hyosung gt250r lost power and wont start


Hi, Happycraz790 and the usual suspects are:

4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.

9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. A severely discharged or damaged battery, you need 12.5 volts or better and be able to pass a load test if necessary.
13. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
14. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
15. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections loose, or connected to the wrong cylinders.
16. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
17. Faulty neutral, clutch lever, or kickstand safety switch.
18. Faulty fuel pump or fuse or relay.
19. A stuck bent or burnt valve.
20. Tilt sensor needs a reset.
21. Security system not disarming alarm needs a reset.
22. Check for engine trouble codes.

Hyosung RX125 I have had an oil leak ever since I dismantled the engine last month. There was a slight knocking, however I went out on it last weekend regardless. The bike started to lose power after 2...


Is your bike making blue/blueish smoke while running? From the stuff you told us, it is either worn piston rings or worn valve seats, but i would personaly bet it's the valves, because the knocking sounds would be the valves being severely out of adjustment, leading to a huge loss of power and many noises. Hope i helped you :)

Hyosung RX125 I have a slight knocking from the engine. I adjusted the valve clearances to their proper settings but still no change. I dismantled the the engine further but could see no obvious problem....


It sounds like you have the cam 180 degrees out of time. The engine locks up because the piston is hitting an open valve. Hopefully the valve is not bent.
