1992 Yamaha TDM 850, I bought this as a project bike. It only has a little over 8000 miles on it, its been stored twice. Carb work done a few years back. Now the bike will just idle and canĀ“t put choke in all the way without it dying. When the choke is pulled out a little bit (about 1200/1400 rpms) and you go to rev it up or give it gas, it dies. What is the problem. For a 92, this bike looks great.
