So I've got a leaky gas tank on my Jincheng 250cc, probably left over from a collision I had with a scooter a couple months back. Definitely not something to ignore (though I managed to for a couple weeks). Anyway, I've got someone who's going to take care of the welding for me and I just wanted to check around to see if I'm not getting ripped off. Does 400 RMB sound about right? It's hard to tell as it is pretty specific and specialized work, so I could probably understand, but I wanted to check first. Thanks in advance!
