    if they have never been done the old leaky crank seals will suck the oil out of the gear box and you will smoke heavily. I trashed a transmission this way. Luckily I had a spare motor. They are cheap and fairly easy to replace.

    I'm having trouble with the contact points in my bike. I have a 1971 f7 that I bought off someone that came with a bunch of parts including new contact point breaker and a condenser. I don't know where it goes. Everything I've found points to inside the flywheel but I cannot for the life of me get the thing off. I ended up beinding the bolt that comes out of the flywheel in the process of getting this damn thing off. I'm getting really frustrated here I would appreciate any help

    There are no points in the flywheel, that is your stator I think
    and you have really mangled that which is the end of the crank
    I think it has a CDI ignition

    You think I can just leave it since that flywheel ain't going nowhere?

    Now you have a problem, you need to get the nut back on...
    And you have pretty well bent the threads.
    You need a "split die"
    Put it on behind the bent part, add some cutting fluid and work it off.

    You probably want to continue and get the flywheel off and replace that crank seal.
    Lesson Time
    It looks like you used a puller with a wide pointed pin
    You need a specific puller with a flat face and a small pin to keep it centered
    And then you want a harmonic balance type that has the bolts to thread into the flywheel
    I did something similar to mine, and used a split die to fix it.

    Another idea to help a bit.
    Get the split die
    Fix the threads
    Get 2 or 3 nuts on the threads to "protect them"
    maybe even put a smaller nut inside the outer nut to protect the end of the crank
    And try again
    Leave just enough space between the flywheel and the closest nut for the fly wheel to "PoP" off

    I was able to get the nut back on with your advice, very helpful btw thank you, and tried to pop off the flywheel but the thing didnt want to come off and I didnt want to superman anymore metal. I thought I had no reason to get into the flywheel anymore that was until I noticed I messed up the coils a bit from threading the bolts of the harmonic balancer a little too deep and turning the flywheel. Now the Coils look like this and I am not getting any spark. Pretty sure I need new coils. What do you think? I looked up the price of the two coils (primary coil and pulser coil) and i would have to pay about $230 total. Does anyone know any cheaper or alternative solutions?

    We both put ourselves in a very similar situation lol. Except now the washer is stuck. At this point I am literally having dreams about getting this thing off. I've applied a LOT of torque, heat, hammer taps and still nothing. Not even budging, used marker to see if it moved at all and there has been no difference. What am I supposed to do?
