I my bike back from the shop. They got the rear sprocket lined up for me. The bike runs good. Still needs some tweeking. My question, the oil I got to mix said that it replaces 16:1 through 50:1 mixes. So I just followed the oils intrsuctions and everything seems fine. Should I still mix the gas to 16:1? I put a picture to show what the bike looks like so far. You can see the shortness of the cables. And I haven't put the rear fender or the chainguard on. I'll be finshing all that good stuff over spring break.
