Sadly on this one, it's not on the handlebars. I had an 81 CMT400 that had the choke on the handlebars, it was great. This one is on the left side, near the starter for the key. I'm going to put everything back together tonight or tomorrow, and try starting it. I haven't had a chance to deal with it all week. If it doesn't start, I will need to bring it to someone to fix because I can't figure out where its wrong. The issue is that I had it running fine before, but then I had to replace the overfill diaphragm, put everything back together, and nothing. Hopefully I can get it done this week to get it running, time is running out before the season starts, and I want to be up and running well before the season starts.
