I don't know about the SYM Orbit II model because I haven't tried it. However, in the case of scooters, if you do regular maintenance properly, you can usually drive for about 70,000 to 80,000 km without any problems. Also, if it breaks down and you get it repaired, you can drive for about 100,000 km without any problems.
Hello there! Nice video!! One question, when replacing valves, it is mandatory to do a Valve Seat Work (Grinding the new valve with the valve seat) or it isn't necessary?
hello great video. my 125 cc scooter has broken down. it started less and less well and now not at all. compression, valves and ignition seems good, new carburetor. Where do you think this could come from? it's a 125cc GY6 Jonway from 2007
It may not be accurate as I haven't checked it myself. As the ignition coil ages, contact or electrical transmission may become unstable. Additionally, the ground electrical line connection to the undercarriage may be unstable.
@@MotorcycleRepair thank you for the answer I will change the CDI and also the stator. when I manage to start it very difficult. The engine runs very well and when hot it starts again well, but when cold starting is very difficult.
120 000 km in 3 years, not bad delivery scoot
That's cool.
amazing and super valuable video. thanks a lot for your time. I have a fiddle II and your video is going to be extremely useful!!
Thank you for your kind words.
Hi there, could perhaps tell me if you know how long a SYM Orbit II is likely to last if serviced regularly? Awesome video 🎉

Hello, please, what are the valve clearances for the exhaust and intake. Thank you very much and have a nice day👍🛵
Normally, if you adjust it to 0.05mm, there is no problem.
@@MotorcycleRepair👍Thanks

It depends on the condition, but most do not do Valve Seat Work.

@@TheMrRexsmith That symptom also occurs when the ignition coil connected to the spark plug is bad.
@@MotorcycleRepair Hello, it was the stator or the ignition sensor. the jonway scooter starts perfectly now.
what country are you in?
@@TheMrRexsmith thank god. I am in Korea. I am Korean.
허리 다쳐요~조심하세요~!!
걱정해 주셔서 감사합니다. 😄
감사합니다 항상 잘 보고있습니다 도움이 많이되네요 위 영상처럼 밸브를 분해하고 조립할때는 밸브의 캠축도 상사점에 따라 맞는 위치에 놓아야 하는지 궁급합니다!! 미리 답변 감사합니다
밸브의 캠샤프트가 정상적으로 장착이 되었다면 상사점은 따로 맞추지 않아도 됩니다
궁금합니다 유튜브 정비영상을 보게되면 오토바이 부품을 통의넣고 세척을 하던데 그 세척물이 따로살수가 있나요? 보통은 세척크리너 뿌리는거를 쓰게되는데 뿌리는거 보단 통속에 담아서 세척하는게 더 세척이 잘될거 같아서요
통에 넣고 세척할때 사용하는 것은 휘발류입니다.
대부분 센터에서 사용하는 세척은 휘발류를 사용합니다.
감사합니다

걱정해 주셔서 감사드립니다. 😄
엑맥300 운행중 입니다 운전스타일에 따라 다르지만 평균 몃키로 정도에 구동계 교환하는지요?
30000~35000 정도에 상태를 보고 교체를 하는것으로 알고 있습니다.

선생님 저기요. Sym은 동판 가스켓 나가는게 고질병인데 이게 주요원인이 뭐라 생각하십니까? 동판품질? 엔진냉각라인구조? 엔진열? 참 궁금합니다.
엔진 헤드 볼트의 조임이 점점 풀어지는 현상이 있지 않을가 생각해 봅니다.
2분14초화면에 보면 바닥에 플라스틱 통에 있는데
카울 핀 저거 어디서 구하나요?
아 참고로 혼다는 개당 900원인가 받던데 그거 말고 싸게 구하는방법 있을까요?
싸게 구하는 방법은 잘 모릅니다. 대부분 오토바이 센터에 부품을 공급하는 곳으로 부터 주문하여 사용하고 았기 때문에..다른 판매처도 잘 모르고, 가격이 싼지 비싼지에 대해서도 잘 모릅니다.
👍👍👍👍👍👍👍👌
thank you 😍
En serio que ese motor tiene 120mil kilometraje???....y nunca fue intervenido???? No puede ser😮
Hay muchas motocicletas que se utilizan para trabajos de reparto en Corea.
Por eso estas reparaciones de motores de motocicletas son frecuentes.
