    No data sheet? Nothing on the coil to indicate which is which? I'm guessing the colors are standard for the XS650, so maybe you can find a wiring diagram for that bike? Or, maybe you should contact MikesXs to see if they can tell you.

    Ok, after a search, I found a diagram on another forum that shows the brown is power, and orange goes to the points.

    got er wired up and we have spark.. now to figure out why the things so hard to turn over. Might have to tear the crank case down and rebuild it too..

    The bike sat for the better part of 3 years with gas in the oil.. yikes.

    Well, before you tear the engine apart, and if you are referring to hard cranking with the starter motor, then R and R the starter motor and clean up the commutator. Makes a world of difference in cranking speed and starting. Here is a rotor from a friends CB550 that I spun on my little lathe:

    After


    I also did the same to my CB450. It's a world of difference.
    Ride. Enjoy. Life is simple.

    Fresh grease in the sun gears driven by that armature can help plenty, too. The grease in mine had turned to hard wax.

    yeah i finally got the drain plug off and about a gallon of gas/oil mixture came out. Must have been sitting there for this whole time. The bike wont even turnover using the kick start so im thinking somethings binding up for sure.

    I pulled the left side(starter side) of the engine cover off and it seems pretty clean (probably from all that gas). Ill go through the right side tomorrow and look at everything and spray some degreaser and new lith grease on the chain tomorrow.

    Any other ideas why stuff would be sticking (other than the starter).
