    I mean it looks like I can just fabricate something I put the washer that's behind the bolt on the magnet in the crankshaft keyslot and it fit now of course I have no idea if even after cutting it would it be thin enough to fit through the magnet slot they seem like different sizes

    there are 4 keys in the motor - take any one to match size - you need a pretty good fit there because it needs to stay in place while magnet is trying to pull it up as you put rotor on (use a sewing needle thru the slot to hold key in place while fitting rotor)

    Where are the 4 keys located well other two which one would be easiest to take off and use to size and are you positive they are all the same size in each part of the motor if so that's what I will do

    never seen a difference in the slots of the two shafts, but once saw a factory that used wrong size fittings on the pieces that went onto the shafts - the one under the drive sprocket is easiest to remove with the puller tool that comes with kit

    I got another key and when I went to install it of course I pull it out and the other is somehow magically reappeared attached to the magnet so at me asdt least I have a spare. So I realized the motor won't mount to the front of the bike that's why the double threaded screw was missing on one side but I can still secure it with three. my question us with the key is the magnet supposed to turn or stay still when you move the bike I put it in at 1 o'clock but it moves when I move the bike is it supposed to

    My next question my spark plug has oil in it is that ok I'm changing it but I assume the next one will have the same. and what plug should I put in it ngk irridium or Bosch like whats the part number all I see are different ones and there's oil coming out of the exhaust and it's leaking gas maybe from the idle screw maybe from the line but the line seems secure not sure how tight the screw should be

    it is called a rotor because it turns with the motor - I think you need someone to look at and help you with this

    I got it to crank up it felt like it was running a little rough though and hot and the back tire locked up again do I need to adjust the clutch cable is it just not grabbing while engaged to let the wheel spin freely

    in that case, you need to shorten the chain or move the tensioner farther back toward the wheel

    BE VERY SURE IT CANNOT BE ADJUSTED WITH TENSIONER BEFORE SHORTENING CHAIN TO WHERE IT IS TOO SHORT
