Few days ago I purchased a 2005 Yamaha Kodiak 450. It only has 16 miles on it and looks like new. No signs of use, everything is clean. Owner just rode it 2 times and sat in storage for 4 years. It runs great but the carb seems to be needed some kind of adjustment. It wont idle with the choke in the "off" position even with the engine fully warmed up. It kind of runs rough at idle. I need to keep the rpms high (with choke 1/4 on) so it wont die on me. Do I just play with the Idle Speed Adjustment at the carb? Or take it to Yamaha? Please let me know! Yesterday I changed the oil and coolant. Still need to change the oil in the diffs.. Here are some pics!
