Question about 1973 Yamaha DT 360
On my '74 yamaha dt360 when i kick start the bike, the throttle opens wide and wants to tac out. The cable from the handle is loose and i dont know why its opening up all the way...can you help?
It has been 35 years since I worked on a 360 as a mechanic at Lynn's Yamaha in D.M. Iowa. You have one of the few left alive. Pull the air cleaner off and look at the slide in the throat of the carb. Does it move all the way up and down freely when you twist the throttle? Is there play at the top of the adjuster on top of the carb? I think your bike has an oil pump for the 2 stroke oil. Remove the front right cover plate, (I think it had a right casing cover separate from the pump cover), and look at the operation of the cable wire on the pump. Both the slide and the oil pump cables should have some free play.
Are there reeds on your carb? The reeds will be between the carb and the cylinder if you have them. Are any of the reeds cracked or broken? Are all reeds fully closing? What condition is the rubber between carb and manifold? Get back to me with the information and we can go from there.
