Just Cracked the Frame... What went wrong

    I will try to keep it to the point. Note this is not my first time pulling a motor, but I know mistakes were made somewhere . I want some input so it doesn't happen when I pull the second motor.

    2013 ZX6R on front headlift and rear stand. Wheels still on, suspension still on. Jack placed under motor. Main engine bolts loosened. (Maybe needed to loosen the lower engine bold more. Removed top and middle engine bolts. Jack still under motor. Went to remove lower engine bolt and found it to be tight. Tried to take some pressure off of it, still tight. Thought maybe it was just put on too tight last time. Turned it, and snap. Cracked the bottom of the frame. Where did I make my mistake?

    Steeltoe What's my move?

    Maybe should have started at the bottom and worked your way up?

    The bottom one towards the rear? If I remember right that one has the adjuster for the frame? You have to take the nut off from the left side and then turn bolt in clockwise to relieve tension and then slide the bolt out.

    That would be the spot. If this is true then I was tightening it up and cracked it. Now I know why I still can’t get the motor out. Hopefully I didn’t strip anything. Thanks for the feedback

    Ive always found it's a good idea to break all the bolts loose before removing any of them.

    I’m with you. I thought I had to loose enough.

    Kawi's have a sequence to remove and install motors. Guess this will be one of those things that's learned from experience vice wisdom.

    And for those of you that "trust" your bikes came from the factory properly assembled, trust not. Not to mention it still has a final assembly at the dealership, by the new guy, who may have been a former heavy truck mechanic, whose choice of tools for any job will be overkill.
    No bike is yours 'til you own it. To own it, I mean you've taken it down to the frame and back, properly, while correcting the discrepancies. Now it's the new best friend that you trust with your life.

    Just tryin' to illustrate a point. I could have said AMI grad. ;)
    Everyone wants to be a motorsports technician...and some places will take anyone just to have a janitor when there's no bikes to assemble. :D

    Worst part about this is I had looked at it earlier in the day on my computer and didn’t go back and check when I was having a problem. Shit happens and another lesson learned that I won’t forget.

    Correct, Top, middle, bottom. There will be more lessons learned I am sure.

    100% accurate.

    powersports are so specialized these days one could specialize in a specific street or dirt or side by sides or personal watercraft model and do well enough.

    So do GSXR's....They have thrust (threaded) spacers at the rear motor mounts that have to be dealt with once the outer nut is taken off the motor mount bolt(s).

    I don't live in those areas, but I could do okay only taking in customers with "competition-style" 2 or 4 wheelers while being selective about what I take in.
    That means I would not work on neglected, mud-caked utility vehicles, bikes with finicky and expensive OEM bodywork, anything Euro...or clapped out SVs. :D

    My previous comments were geared towards looking over one's "new" bike cuz I guaranty there will be discrepancies. Some may merely be acceptable so-so issues easily resolved, while others are completely of the WTF were they doing variety.

    Honda's have their version as well.

    oh yeah I get that. A good friend, who has been wrenching on bikes for years, flat out refuses to work on anything with more than 2 wheels or snorkels. Sorry tricycle riders...lol

    There used to be a dirtbike shop here the guy would get $300 for a "new bike service" Basically uneffing what local dealer techs did or didnt do to prep a fresh dirtbike, adding zerks, maintenance items, & setting up the sag/suspension for the owners. He had hundreds of hours worth of work every week.
    A first I thought... man your customers must be rich!
    Now I see what a bargain it was.

    Just exactly how much "assembly" is there by the techs at a dealership when they uncrate a bike? I was assuming there wasn't much. Now you guys are making it sound like they install the motors in the frame and stuff.
