tore into the motor tonight. The detent spring wasnt even attached, just found it sitting in the bottom of the motor. Also was greeted with rust on the crank and the cylinder wall. Thankfully none of the bearings seemed to be pitted so have to sand down the rust, re-attach the spring, and put the motor back together. Hopefully I will have the motor back in one piece and ready for re-installation by tomorrow and re-assemble the quad Saturday morning. Then I can get a ride in sometime this weekend! Also a leaky seal on the output shaft...
See the spring just hanging out in the below picture? That little guy was what was causing my shifting problem...
She is hanging there ready and waiting for the open heart surgery to be completed
