Okay so I am still learning. I took out the motor and had it rebuilt and am now in the process of putting it all back together there is just one wire I can't place and I think that it is the engine ground. It is black with an o-ring connector and I am assuming it connects to the rear cylinder. But for the life of me I can't find out where and the shop that did the work removed all my labels. That is assuming I labeled it. Any help would be appreciated. Just a few more things like this and my bike will be back on the road. Hurray!
