Thanks a ton @SkyDork! @scout, the guy the did whatever, when I complained about my bike running fine before I gave it to him. He back fired and got aggressive. The reason I gave someone to work on my bike is because I have a full time job so I couldn’t do it myself, in Hong Kong we do not have garage space, it’s just parking lots and no one (workshop and mechanics) would be willing to share their tools to fix my own bike. Cause they rather get paid. So tadaaaaa, either way, I am going to dig into my bike this weekend and try my best to sort it. I know my bike inside out cause I built it myself but the problem wasn’t caused by me so I will have to dig in. Wish me luck! Thanks again!!
