i have a 85 yamaha ytm 225dx and i am having some issues with it. one minute the bike runs like a watch and the next the machine acts like its staarvin for fuel. it idles great and starts up with no problems. i start it up and take off and as soon as the throttle gets to the 3/4 position the motor cuts out. it does this in every gear. i can never open it up like i want to. i have cleaned and checked and re checked the carburetor and everthing checks out. has good gas and mechanical timing is on. the valves ae set to the correct lash. i heard that the cdi's can go bad, but i have three othe yamaha trikes from that era and none have ever done this. i am looking for some advice before i go spend the money on a stater and cdi. if anyone has any extra parts let me know and your advice is much appreciated.
